The 542 gas analyzer is a versatile, programmable gas analyzer based on the principles of thermal conductivity. Capable of measuring almost any combinations of gases; hydrogen, helium, oxygen, carbon dioxide, methane, carbon monoxide, argon, nitrogen and many others.
This gas analyzer instrument is especially suitable for measurements of mixtures containing hydrogen or helium. With the use of sensitive floating circuits, the thermal conductivity analyzer can detect gases down to parts per million levels and up to full concentration.
The analyzer is pre-programmed for a wide range of sample and reference gases, easily selectable from the simple front panel menu.
Calibration settings for each combination of gases used, are stored in an internal memory and are recalled automatically, every time a particular gas mix is required. This enables quick and easy switching between gas combinations.
Sophisticated microprocessor electronics enable the fastest possible response time, excellent stability and flexibility. Sample pressure and flow are internally controlled allowing connection to a wide range of pressurised samples. Automatic calibration is included as standard, the instrument can be set to perform at zero and span calibration at timed intervals.
Measurement range : ppm and %. Dependent on selected gas mix. Adjustable, auto-ranging. Typical 0-1000ppm (H2 in N2) 98-100% (O2 in Ar)
Resolution : 0.5% or better
Accuracy : ±2% of scale of the stated typical value
Response Time : 90% of reading in 20 seconds
Suitable gases : Hydrogen, helium, oxygen, carbon dioxide, methane, carbon monoxide, argon, nitrogen and many others
Unsuitable gases : Corrosive gases
Ingress protection : IP40
