Feature:
1. The large LCD display, English menu operation.
2.Multi-parameter display at the same time: the value of conductivity,temperature, output current, alarm points, etc. Intuitive and easy to read, and alarm for range over run.
3.Screen displays alarm status and accompanied by a switch ON / OFF signal output
4.Automatic Temperature Compensation: Automatic 0℃ to 60℃
5.Communication function (optional): RS-485 communication interface(MODBUS protocol is partially compatible), 4 to 20 mA current output corresponding to the DO value can be set freely.
6.Notepad: can store 50 measurements, the user can record measurement data.
7.Hysteresis amount can be set freely to avoid frequent switching relay action
8.Watchdog function: to ensure that the instrument will not crash
9.Core devices from famous foreign brands
10.Restore the factory settings. Power-down protection> 10 years
