PB-301 type ORP transmitterDetailed product description：

PB-301 ORP transmitter is a suitable ORP transmitter for industrial processes, with dual high impedance inputs and 4-20 mA standard signal output. The output signal can be connected to an ORP controller or computer terminal.
When used in conjunction with HT2513 type ORP composite electrode and 2615-D type ORP composite electrode with grounding electrode, it has strong anti-interference ability and is particularly suitable for ORP measurement in complex environmental conditions.
Power supply: 220V, AC.

The PB-301 ORP transmitter meets the IP57 waterproof rating and can be used in outdoor and humid environmental conditions.
