The EC 24 is a robust transmitter for monitoring of toxic gases, oxygen and hydrogen in air. The electrochemical sensor is highly selective and thereby reduces fault alarms. The amplifier of the transmitter assures a safe transmission of the measurement signal towards the controller. Potentiometer and measurement contacts behind a service lid allow for easy calibration on-site. The casing is available up to IP 68, which means that it is dirt-, dust- and waterproof. The transmitter can be operated as a stand-alone unit or in connection with a GfG-Controller.
