READ THIS REVIEW CAREFULLY - READ THIS REVIEW ALL THE WAY THROUGH BEFORE USE. 5 STARS for the product. 0 STARS for the instructions. The instructions are down right dangerous. I own 2 AW meters and .75 and .92 standards for calibration. After weeks of trial and error I can tell you that in my experience this meter is actually very accurate. But NOT if you just follow the instructions. First off the instructions say the test time is 5 min. It's not. It takes hours to run the test accurately. Second the instructions DO NOT tell you that you need to calibrate it to standards WHICH YOU MUST DO. Following the instructions, I got crazy readings all over the map. The lower aw standard would typically come in pretty close pre calibration. But the higher aw standard reading would be erratic and unreliable. I was going to throw the meter out before figuring out my test procedure - which sucessfully calibrated the meter to standards. MY test procedure. Step 1 - Put the sample in the testing cup and place it in the meter. Close the meter on the sample. Don't turn the meter on. Step 2 - WAIT several hours (even overnight). Step 3 - Turn on the meter with it still closed on the sample. Step 4 - Read the results Before use you MUST calibrate it to standards, in the range you are testing for, from a reputable lab (using the procedure above). You need 2 different standards of different values close to the food you make to do this safely. Annoyingly the standards cost almost as much as the meter. But without them you can't use this safely. I have seen 1 star reviews where people explain that the meter gives erratic results when tested using standards. And they are correct if you use the instructions that come with the product. But at least in my case, using the procedure above, I can get the meter to read the standards accurately. In fact it's actually more accurate than my expensive German AW meter. NOTE, I test it with a standard every time I use it to confirm it's reading correctly before trusting the results with food. After all this is food safety we are talking about. DISCLAIMER: I am just a consumer reporting my experience with the product. I do not speak for the manufacturer. Before trusting any product like this you MUST verify that it is reading correctly using standards. I only wrote this because the included instructions are JUNK IMHO. Review: AW meter - Instruction guide is missing. We don’t succeed to connect meter with computer. Cannot find proper / clear instruction manual on the internet. ## Features - Please note: 1. It is saturated solution of sodium chloride, if there is white powder precipitated out of the bottle, it is sodium chloride crystals, rinse off with water, it does not affect the use of. 2. It is normal for a saturated sodium chloride solution to have no dissolved sodium chloride, indicating that the solution is 100% saturated. - AMTAST Water Activity Meter is often used to measure the dryness enduring ability of the microorganisms. By measuring the water activity of food and selecting reasonable packing and storage methods, the use of preservatives can be reduced and the shelf life of food, grain and fruits and vegetables can be judged. - This is a real portable water activity meter lighter than a mobile phone and with precision of 0.02 aw, easy to measure water activity anytime and anywhere. Easy reading, water activity and temperature of the samples displayed together. - Fast testing, measures the water activity in 5 minutes. Sensors and readings are integrated. Put the samples in sample boxes and meters are placed on them until the data are stable. - With Cable and software for PC. Use USB data output to connect with PC. (Provide Bluetooth data output for choice.) 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. ## Technical Specifications | Specification | Value | |---------------|-------| | Manufacturer | AMTAST | | Part Number | WA-60AS | | Package Dimensions | 27.3 x 20 x 8.1 cm; 910 g | | Item model number | WA-60AS | | Colour | Usb Cable and Software Version | | Material | Stainless Steel+ABS | | Batteries included? | No | | Batteries Required? | No | | Item Weight | 910 g | ## Images ![Water Activity Meter Smart Food Water Activity Tester for Food Jerky Dried Fruit Grain Vegetable, AW Monitor Water Activity Testing with USB Data Cable & Software WA-60AS - Image 1](https://m.media-amazon.com/images/I/81qaBfyRTpL.jpg) ![Water Activity Meter Smart Food Water Activity Tester for Food Jerky Dried Fruit Grain Vegetable, AW Monitor Water Activity Testing with USB Data Cable & Software WA-60AS - Image 2](https://m.media-amazon.com/images/I/814C1qcxaeL.jpg) ![Water Activity Meter Smart Food Water Activity Tester for Food Jerky Dried Fruit Grain Vegetable, AW Monitor Water Activity Testing with USB Data Cable & Software WA-60AS - Image 3](https://m.media-amazon.com/images/I/81bIXbHyYaL.jpg) ![Water Activity Meter Smart Food Water Activity Tester for Food Jerky Dried Fruit Grain Vegetable, AW Monitor Water Activity Testing with USB Data Cable & Software WA-60AS - Image 4](https://m.media-amazon.com/images/I/7175sFmdffL.jpg) ![Water Activity Meter Smart Food Water Activity Tester for Food Jerky Dried Fruit Grain Vegetable, AW Monitor Water Activity Testing with USB Data Cable & Software WA-60AS - Image 5](https://m.media-amazon.com/images/I/81wI1Gnlv6L.jpg) ## Available Options This product comes in different **Color** options. ## Questions & Answers **Q: How long is the factory calibration valid for?** A: This device is factory calibrated and users do not need to calibrate it.
