GREEN PRIMA Online ORP Analyzer
GREEN PRIMA Online ORP AnalyzerIt can be widely used for continuous monitoring of ORP values in solutions such as thermal power, chemical fertilizers, metallurgy, environmental protection, pharmaceuticals, biochemistry, food, and tap water.

The online ORP analyzer has the following advantages:
A multifunctional relay with functions such as cleaning, periodic alarm, error alarm, etc;
The historical curve function of ● * can record 600000 data and has query function;
The backlight automatically turns off after three minutes without button operation, which not only saves energy but also extends the service life. The screen contrast and other parameters can be adjusted;
The Chinese and English operation menu of ● * brings great convenience to users, and they can use it freely without reading the manual;;
All use imported chips and components, as well as a brand new surface mount production process, to ensure stable and reliable instrument operation;
● Large screen backlit LCD display, with clear visibility of pH value, temperature, time, and relay status parameters;
● 2-channel 4-20 mA current output, RS485 MODBUS RTU protocol, convenient for remote monitoring and communication on the computer;
Adopting a waterproof and airtight fully sealed shell, it can be used in extremely harsh environmental conditions with protection up to IP65.
