Product Description-----The activity meter can measure bread, biscuits, cakes, puffed foods, snack foods, dehydrated foods, dried fruits, meat clams, preserved fruits, etc. It 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. It is often used to measure the dryness enduring ability of the microorganisms
Technical Parameters-----Display: 6 bit backlight LCD digital display, 3 bit humidity aw, 3 bit temperature display Range: 0~1.0aw Resolution: ±0.01aw Accuracy: ±0.02aw : Non conductive humidity Sampling Time: 5 Minutes Operating condition: Temp: 0~50°C (32~122°F) Humidity: <95%RH Power supply: 2x1.5V AAA Um-4 Battery Size: 135x70x44mm Weight: 100g (Not including batteries) Standard Accessories * Main Unit * Sample Plate * Carrying Case * Operation Manual
Measuring Procedure------4.1 Press the power key to switch on the power and the gauge enters the auto mode which can automatically test the water activity. 4.2 Put the samples into the sample plate, and then cover the of the gauge onto the sample plate. Lay aside for about 5 minutes, when the reading gets stable, the water activity can be obtained. 4.3 After testing, press and hold the power key for about 3 seconds to turn off the gauge. Clean the sample plate for next use
READING CORRECTION------When it is necessary to correct the reading value, press and hold the Power Key for about 7 seconds. Then release the key when the signal ‘Cor’, comes out on the display. There will be a decimal number with two places, which is the correction value. Then open the battery cover on the back, there are 2 small hole below the battery slot. Use a small hard bar (such as screwdriver) to slightly touch the key inside, the correction value will be increased or decreased
Product Feature-----The can be used to measure the water activity of foods. No matter when and where you need to measure water activity, water activity meter is your unique choice. This is a real portable water activity meter, with a weight of only 100 grams, lighter than a mobile phone, and a precision of 0.02 aw, easy to measure water activity anytime and anywhere

Product Description

The Water Activity Meter 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. It 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.

The machine can be used to measure the water activity of foods. No matter when and where you need to measure water activity, water activity meter is your unique choice. This is a real portable water activity meter, with a weight of only 100 grams, lighter than a mobile phone, and a precision of 0.02 aw, easy to measure water activity anytime and anywhere.

Product Feature

Fast test, The test time of our activity meter is greater than 0.25 and less than 0.85, generally 10 minutes to 20 minutes, less than 0.25 greater than 0.85, the minimum test time is 30 minutes to 1 hour

Easy reading, water activity and temperature of the samples displayed together.

It has automatic shutdown, manual shutdown function and undervoltage alarm indication function.

Can this item be used to test non-dry food items, like jam or paste?---Yes it can.

What is the method used to determine Aw?---It tests the AW value by the meter on the bottom part. It works by placing a sample in a sealed measuring container. When the vapor pressure of the water in the substance and the water in the air reaches equilibrium, the relative humidity of the air surrounding the sample is equal to the water activity of the sample. The principle is film capacitor method

Can it be calibrated by myself? How to calibrate?---Yes you can calibrate yourself. Please kindly read the manual with Reading Correction part.
