TS 2000-DO Dissolved Oxygen Transmitter – Switch is a compact and reliable instrument designed for accurate online dissolved oxygen (DO) measurement in industrial and process applications. It works with a DO electrode and provides a stable 4–20 mA analog output, with optional relay (alarm) output and RS-485 MODBUS RTU communication for automation systems. The transmitter features a backlit LCD display for clear local indication and supports a measurement range of 0 to 20.9 ppm. With high accuracy of ±0.25% of full scale, fast 1-second response time, and excellent repeatability, it ensures dependable performance. RTD PT-100 temperature compensation improves measurement reliability under varying process conditions. Housed in a corrosion-resistant SS-316 enclosure with IP-68 protection, TS 2000-DO is ideal for water treatment, wastewater, and industrial process monitoring applications.
Configure the transmitter and electronics based on application, environment, and compliance requirements.
