OxyTrans-EX Explosion-Proof Oxygen Transmitter

Brand: Edgetech Instruments

4-20 mA Loop Powered Two Wire Oxygen Transmitter

  • The Edgetech Instruments Model OxyTrans is an easy to use, accurate and economical way to measure Oxygen at trace and % levels. A simple display and one point calibration allows for a quick start of the instrument.
Measuring Range

  • The unit will offer ranges between 0-100ppm, 0-1,000ppm, 0-10,000ppm of oxygen. 0-1% to 0-25% O2.
Sensor

  • The OxyTrans uses a special fuel cell to measure the oxygen concentration. The sensor meets the industrial requirements for accuracy, sensitivity, easy to use and operating life.
Calibration

  • The calibration of the instrument for trace oxygen measurements in gas should be done with a known calibrated gas. The concentration can be chosen freely within the measuring range.

Flow-Through Measuring Cell in Stainless Steel

  • The measuring cell is modular and made of stainless steel. A defective measuring cell can be repaired by replacing the defective part only, rather than the complete unit.
