O2 Monitors for Glove Boxes and Nitrogen GeneratorsIndonesia Industrial Parts

O2 Monitors for Glove Boxes and Nitrogen Generators designed specifically for measuring oxygen in glove boxes from air (21% O₂) down to low levels (0-10 ppm O₂). This oxygen monitor range has easy installation options that ensure the best fit with the glove box operators needs.

The analyzer or remote sensors can be connected directly on the glove box using a KF-40 flange. In the remote version the oxygen sensor can be placed in the glove box using our sample/calibration module.

O2 Monitors Highlights

Measurement ranges from 0-10ppm up to 0-25% O2
Accuracy of better than 2% of selected range
24 months sensor life span (in normal use)
4-20 mA output
18-24V loop powered
XLT sensor options for CO2 backgrounds

GPR-1500 GB

For trace oxygen measurements as low as 0.1 ppm O2 in various background gases. The sensor is housed in a stainless steel case that can be screwed into place.
