Trace PPM Oxygen Transmitter Analyzer is used to measure the O2 content in the glove box system. The range is 0-1000ppm, it is linear at 0-100ppm, and it is an estimated value beyond 100ppm.
This analyzer is made of oxygen-sensitive zirconia, but due to the high temperature of the probe and the reaction of the platinum surface, there will be a slight cross-reaction to hydrogen and other sensitive gases. This will shorten the life of the analyzer.
Trace PPM Oxygen Transmitter consists of a probe and a special circuit, and the interface is NW40 flange seal. The probe is protected from physical damage by a protective cover. The signal connection port is a vacuum-sealed interface. The circuit is installed in a sealed housing behind the NW40 flange.
The analyzer’s circuit operates at 24VDC. Output 4-20MA or 0 to 10VDC according to oxygen content. And there is a heating switch to control the temperature of the probe. The circuit and probe components are calibrated by the manufacturer’s standard gas; there are no components that require customer adjustment and maintenance.
(Note: If there are special requirements, we can consider providing a calibration method that allows trained technicians to recalibrate the accuracy of the probe below 100ppm.)
The oxygen probe is fixed by the NW40 flange vacuum-sealed interface. It is usually connected to the T-type interface of NW40. This ensures that the probe can directly measure the airflow without being in a blind spot. The probe requires a lower flow rate for measurement.
The operation of the analyzer is displayed through a PLC touch screen or another secondary display instrument.
Turning on the analyzer when the O2 content is> 1000ppm (such as air) will not cause irreparable damage to the analyzer, but it should be avoided as much as possible. If exposed to air, it can take several hours to accurately measure the O2 content of the inert gas.
