User’s Manual Datasheet

O2 Monitors for Glove Boxes and Nitrogen Generators

Features

Measurement ranges from 0-10ppm up to 0-25% O2

Accuracy of better than 2% of range

24 months sensor life span (in normal use)

4-20 mA output

Designed specifically for measuring oxygen in glove boxes from air (21% O2) down to low levels (0-10 ppm O2), this oxygen transmitter 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.
