DO 100S Digital Dissolved Oxygen Transmitter

DO 100S – Dissolved Oxygen TransmitterDescription

Electronet Series DO 100S is a high-performance Dissolved Oxygen Transmitter designed for reliable and continuous online measurement in industrial applications. It accepts input from a DO electrode and converts the signal into a standard 4–20 mA output (optional HART).
The transmitter includes an LCD display for real-time indication, while Zero/Span adjustments are easily accessible for quick calibration. Its rugged construction and user-friendly interface make it suitable for demanding process environments.
