Oxygen gas transmitter OxyTrans II KF

electrochemical2-wirefuel cell

Overview
The OxyTrans II KF is a loop-powered 2-wire oxygen transmitter designed for trace and percent-level oxygen measurement. It features a simple display and one-point calibration for quick commissioning and continuous process monitoring.

Sensor
The OxyTrans II KF uses a fuel-cell (electrochemical) sensor to determine oxygen concentration. The sensor is designed for industrial use with high sensitivity, stable output and long operating life.

Calibration
For trace oxygen measurements use a calibration gas with a concentration selectable within the measuring range. For percent-range measurements calibration can be performed with ambient air.
