It is used for analyzing the purity of oxygen in respirator machine of medical treatment and anesthesia
machine and oxygen concentrator and high-pressure oxygen house and the nursing case keeping infant.
Instrument sensor is electrochemistry diaphragmatic positron. It makes use of platinum negatron and silver and silver chloride as electrolyte.
Diaphragmatic material is polyethylene film which chooses the permeating oxygen .

Description

Electrode reaction:
Cathode:O2+2H2O+4E-4OH
AG+CL-AGCL
3. Technical parameters:
Electrode current is proportional to content of oxygen in the gas. Through modulus conversion and coding drive, it indicates the content of oxygen by LCD screen.
Measurement precision
0-100% the lowest of distinction is 1% +3%
0-50.0% the lowest of distinction is 0.1% +1%
0-5.00% the lowest of distinction is 0.01% +5%
Environment of temperature:0-40 C
