Description

Ethylene oxide detector-transmitter E2638R-EtO is a member of new PluraSens® family of multifunctional measurement instruments.

Applications include chemical and polymer industry, medicine (hospital sterilization facilities) and other areas where leakage or generation of ethylene oxide is possible.

The instrument utilises novel fully calibrated and temperature compensated electrochemical gas sensor with excellent repeatability, stability and long lifetime.

To connect the detector use two analog outputs and RS485 digital interface with industry standard Modbus RTU protocol.

Two relays with closing contact may be used for remote signaling or ventilation control. The flashing LEDs and an internal buzzer give alarms as well at two set-points.
