oxy.IQ Oxygen Transmitter

  • Two-wire, loop-powered 4 to 20 mA transmitter
  • Intrinsically safe option for Class 1 Div 1 and Div 2 locations
  • User selectable ranges
Product Options


The oxy.IQ from Panametrics is a cost effective and reliable two-wire loop-powered transmitter. It has a 4 to 20 mA output and can measure oxygen in 10 ppm ranges and 7 percentage ranges, which can all be selected by the user. The transmitter is compact and uses proven sensor technology to accurately measure O₂ in a variety of gases, even in hazardous environments.

The oxy.IQ is controlled by a microprocessor that enables the user to select the range, perform calibration and trim outputs. The instrument can be easily programmed using the keypad and display, this keypad allows for complete functionality in hazardous areas.

The oxy.IQ’s oxygen sensor is an advanced galvanic fuel cell that provides superior performance and accuracy.

Also available as an analyser as part of a sampling system.
