How Do Grain Moisture Testers Work?

Moisture in grain can define the quality of your grain as you store or pack them. According to the International Rice Research Institute (IRRI), improperly dried grains such as rice can cause low-quality grains. When grain has inaccurate moisture content when stored, it can generate heat and will become a breeding ground for mold, attract insects, or generally cause non-standard grains. Consequently, farmers or growers, even vendors require an accurate determination of grain moisture— hence, the grain moisture tester. Depending on whether it is tabletop, handheld or with a reading probe, you have to set the tester to the kind of grain you are testing. Then pour in the sample on the pan or stick the probe into a pan of sample grain and then its moisture content will be displayed. There are different means to determine moisture content. But, testers usually use the electric conductivity of the moisture to rate moisture percentage.

Buyer’s Guide:

Advantages/Benefits

One of the important benefits you can have from grain moisture meter is helping minimize wastage because of accurate data guiding the entire grain processing. It also helps speed-up identifying moisture. With a single button and a few seconds, the meter will display the moisture of the grain. Hence, work can proceed seamlessly. Also, this can help in the accurate weighing of the grain. You would know that the weight of the grain is the actual weight and not of the water in it.

Usage prerequisites

Whether you’re a first time user or has been a veteran in grain moisture testing, here are a few prerequisites to remember when using (especially new) grain moisture tester:

  • Be sure that you understand the functions of your grain moisture tester. It might help to know how the adjustments and settings work through the manual to get an accurate reading (i.e. temperature)
  • When preparing the grain, let it set and cool before starting with the testing especially when these grains are newly harvested.
  • Know the different moisture margins and standard percentage for the kinds of grain you’re testing. Always keep a record every after testing to ensure that you don’t mix up data.

Buying Criteria

1. Portability

You can choose to have a tabletop/benchtop or handheld or those with probes. It is, however, dependent on your usage and comfort. Tabletops are relatively heavier and bulkier, which is meant to be stationary inside your lab or storage. So if you want a tester that you can bring in the field, you can have the handheld ones. The difference between these two kinds is that the tabletop can accommodate more grains than the handheld.

2. Accuracy

The very purpose of getting a grain moisture meter is accurate. Thus, the tester should be able to provide the accurate moisture content of the grains to ensure that the grains are healthy and of good quality as it is stored and packed. As I have pointed out earlier inaccurate moisture in storage can cause the grains to degrade.

3. Probe and pans

Handheld grain moisture testers can further be categorized with pans or probes. Pans are the container in the tester where you will fill-in with grain, and from which the meter will test the moisture. Tabletops have bigger pans than the handheld ones. Meanwhile, Probes are two poles or bard connected to the tester that will be stuck on the grains to read the moisture. It is easier, but some users contend that probes are not as accurate.

 

How We Assessed & Evaluated These Grain Moisture Testers

Grain moisture testers are quite specific testers and are not very common household items as these have very specific usage. Thus, it took us quite some time to research the product.

It was a challenge to do the hands-on testing as we need to find different kinds of grains and are under different stages of processes. We first visited online pages like forums, online vendors and product website to supplement or limited knowledge regarding the product. We came up with summarized information from our online research as the starting point for our offline research.

For our offline data gathering, we talked to some growers and vendors about grain moisture testing, what they are using, its importance and how their grain moisture meters work. From this, we created a list of important considerations to weed out some of the low performing grain moisture meters.

At first, we have around 15-grain moisture meters. To cut it to five (5), we ranked them based on their features and benefits.

Once we had our top 5, we then called on a diverse group of testers from beginners to experts for the hands-on testing. We have spent five days to do the testing, one meter for each day with different kinds of grains that has undergone various stages prior to its storage and packing.

The Dickey-John Grain Moisture Tester, Handheld is one of the less intimidating-looking meters from among the five. It is considered or marketed as handheld because of its compact design. But, it is not as portable as the meters with probes.

On testing, our testers initially thought that you would simply be pouring in the grain. However, it is more complicated as you have to turn the container upside-down and pull the stopper at the bottom for the grains to fall into the pan or chamber that can fit in 250 grams of grain. Some of the testers think that the complexity served a purpose, allowing the user to control the amount of grain without having to pour repeatedly manually.

This grain moisture meter also performs well in the accuracy testing. Our testers used it in with different kinds of grains which are under various stages. It shows fairly accurate results that are very close to the pre-identified content moisture of the grains.

I have mentioned earlier that it looks simple, but its operations are a bit complex even for our expert testers. The challenge with the Dickey-John Grain Moisture Tester, Handheld is how to operate the product and to connect it to a computer or other device.

According to our testers reading through the manual and installation took time even with the testers working together. However, once it is completed. It makes the working with the diagnostics and data from the testing easier and more convenient. This feature is useful for recording when you have several grains to test.

Since the product is also a handheld type, the display screen is a bit small. Thus, you need always to examine and cross-check your data for accuracy.

Our testers think that it is more complicated than the Hanchen Lab Fast Halogen Moisture Analyzer Tester For Grain, Chemical Raw Materials, Mineral, Biological Product, Food, Pharmaceutical Raw Materials, Paper. But, you can quickly get the device working when you read through its operating functions.

The testers believe that this product is heavy-duty considering that it can accommodate 250 kinds of grains as provided in its description. We were not able to test these many grains during the testing. However, this grain moisture tester was able to provide precise results from the sample grains that we have.

Our testers are of the opinion that this device can be an excellent tool for those having large quantities of grains to process. As it is a tabletop device, it has a larger screen display. Additionally, its buttons are powered through the touchscreen. Some of our testers think that this feature is fine as most devices have this capacity.

However, during the testing, there are issues with the sensitivity, where the testers have to press several times to make it work. They deemed that you just have to be familiar with the meter. Like the Dickey-John Grain Moisture Tester, Handheld it can also be connected to the PC, or you can even have a USB/flash drive device to transfer and store data.

Next on our list is the Hanchen Lab Fast Halogen Moisture Analyzer Tester For Grain, Chemical Raw Materials, Mineral, Biological Product, Food, Pharmaceutical Raw Materials, Paper, a tabletop halogen grain moisture tester.

This grain moisture tester performs more than just metering grain, but can also be used to determine the moisture content of other materials such as food, paper, and other raw materials. Some of the testers think that this feature makes the product more valuable for users who have other raw materials to work on.

As to its functions, it provides halogen heating with about 50 to 80 degrees temperature. With grain moisture tester, halogen heating pertains to a type of heating process using halogen gas making direct and effective compared to other heaters (such as infrared). This can provide more accurate results helping alter temperature.

Throughout the testing, this meter provides data that are accurate with the predetermined moisture content of the sample grains. Our testers observed that it has a large pan that can fit in about half a kilogram (0.5) of grain, which they think is good sample size. They further said that with this size, you could have the opportunity to truly determine moisture. Thus, our testers believed that it could be suited to those who work with large quantities of grain.

The buttons are quite simple and understandable to use even for the first-timers. It also packs a decent LCD size, where users can easily see through the display. The testers think that it might take me a trivial part, but this can make a difference when you are working on different kinds of grain and in large quantities.

What some of the testers find time-consuming is how they have to pour in the grain. It departs from those with probes that you can immediately put through the grain.

What We Liked
