pH/ORP TRANSMITTER - SWITCH
TS 2000-pH/ORP
TS2000-pH/ORP pH & ORP Transmitter – Switch is a compact and reliable analytical instrument designed for accurate online pH and ORP (mV) measurement in industrial and process applications. It supports pH measurement from 0 to 14 pH and ORP measurement up to 2000 mV, delivering high accuracy of ±0.05 pH and ±5 mV ORP. The transmitter provides a stable 4–20 mA analog output, with optional relay (alarm) output and RS-485 (MODBUS RTU) communication for automation systems. A backlit LCD display ensures clear local indication and easy operation. RTD PT-100 temperature compensation enhances measurement reliability under varying process conditions. Housed in a corrosion-resistant SS-316 enclosure with IP-68 protection, TS2000-pH/ORP is ideal for water treatment, wastewater, chemical, and industrial process monitoring applications.
Configure the transmitter and electronics based on application, environment, and compliance requirements.
