Product Description
It is able to equip more than 1 sensor(4 sensors at most) and can be controlled by software.
Introduction:
Water activity or aW , indicates the free water content when food is stable, measures the possibility of microbial proliferation.
Food formulators use water activity to predict how much moisture migration will affect their product, so that to choose suitable package and storage method to reduce the usage of antiseptics.
Feature:
1.High stability.
2.Long using life in good performance without fault.
3.Better data processing program leads to more accuracy testing result.
4.Chemical resistant. The testing result keeps reliable when testing many different kinds of volatility material.
5.Imported chip inside sensor is with good stability and high accuracy. Avoid passivation.
6.It can save real-time testing value or final testing result. User can also set time to save data. All data can be transmitted to PC and saved as file/sheet.
7.It can reserve 2000 sets of testing results, and results can be saved to PC.
8.No need to calibrate every time.
9.It has RS232 port and USB port, can be connected to mini-printer.
10.It is suitable to test different kinds of material, such as solid, liquid, powder are all OK.
11.Optional stylus printer, can print data for long time storage.
12.The shortest measuring time is 4-5 minutes only.
13.Buzzing when measurement finishes or calibration finished.
