Product details
Application
It can be used for real-time monitoring of the pH / ORP in the flammable and explosive atmosphere (zone 0) and output the measuring the data in the types of digital (RS485) or analog (4-20mA) , connect with PLC or multi-parameter system.
Overview
pH / ORP-8930 Explosion-proof pH/ORP transmitter adopts 128x64 resolution graphic dot matrix display as Human-computer interaction interface, suiting for white background backlight, can display pH / ORP / temperature / transmission parameters at same time. It uses explosion-proof cast aluminum shell,whose sealing performance is good, and it is particularly suitable for places of
thermoelectric, environmental protection, metallurgy, pharmaceutical and other industrial production area that require pH or ORP continuous monitoring.
