Water Activity
The Water Activity mainly reflects the amount of free water in the state of food balance, the stability of food and the possibility of microbial reproduction, and the chemical, enzyme and physical changes that can cause the change of food quality.
Please note:
This meter is calibrated by factory, users do not need to calibrate again, just input samples and test which is very simple.
If you want to verify the accurate, you can make the standard salt solution by the following steps:
1. 100g pure NaCl, add into 200g hot distilled water, stir it. Then wait till to room temperature.
2. Keep the solution into a brown bottle for one week in room temperature.
3. In room temperature 25°C (77°F), make sure the meter, solution, room temperature all same temperature. The solution AW value should be 0.73~0.77

These handheld meters are about the cheapest bench top/mobile Aw meters you can buy and that is for a reason. I knew it wouldn't compare to something like a Meter Group, Rotronic, etc. It worked well for almost 4 months of minor usage and then suddenly started showing much, much higher Aw values. Nothing had changed in the sampling, instrument management or quality. I used a NaCl solution standard and it was actually within threshold of 0.02 Aw at 0.86, but when evaluating samples in the 0.55-0.70 range, would always display about 0.10 off. I am not even going to both reaching out to the manufacturer, as they clearly won't support the product based on the entrance cost. Time to upgrade to a more reliable instrument and instrument manufacturer. Only use this if can't afford to pay for a better quality Aw meter. Or get insurance on it.

I have used this item pretty often in my manufacturing facility. It has worked accurately and was super easy to use. I needed a water activity meter and the competitive products cost significantly more. I would love something less expensive but comparatively it is pretty solid.

Water activity is perhaps the most important predictor of spoilage in dry cured meats. Naturally, being able to measure accurately and consistently is essential. Though this product reacts to input, there are no hard parameters regarding sample size and temp. It has less sophisticated controls than a handheld calculator and no indication of wether or not the reading has stabilized sufficiently. Granted, it is at the bottom of the scale in terms of cost, but I’ll likely purchase a more expensive WA meter to replace it. Given that botulism is potentially lethal this unit does not provide sufficiently convincing data to assure me that the sample is 100% safe. In the coming months I’ll be interested to test it against more advanced instruments to see if the readings correlate. Given that certainty is the object of such an instrument I can’t recommend this product in good conscience, but I also can’t say conclusively that it does not work.
