Description:
Dual TDS meter, it can detect the TDS value of the influent and effluent,  quantitatively remind alarm, display temperature and use time

Powered by 3PCS AAA Batteries, batteries are not included

The interface is divided into two interfaces, namely the inlet and outlet impurity probes and temperature interface?

Interface 1 is marked with NTC1, GND, and ZZ1, it stands for temperature sensitive resistor interface, ground, and impurity 1 interface

Interface 2 is marked with NTC2, GND, and ZZ2, it stands for temperature-sensitive resistor interface, ground, and impurity 2 interface

Note: The temperature sensitive resistor interface is only valid for NTC1 and it needs to share GND with the impurity interface

Package Includes:
1 X Dual TDS Meter
