Versatile Moisture Analyser for gases.
The new Series 500 Moisture Analyser from Systech combines microprocessor control with a high quality phosphorus pentoxide electrolytic sensor for absolute measurement of moisture content.
On-line oxygen analyser is fast and accurate
The Systech Series 800 On-line Oxygen Analyser is a versatile, maintenance free and programmable instrument providing a very fast response to changes in the oxygen content of a process gas
Especially suitable for binary mixtures containing hydrogen or helium, the Model 542 is a fast and accurate method of monitoring gas mixtures.
The Systech Model 542 is able to measure any combination of non-corrosive gases using the principle of thermal conductivity combined with sensitive, microprocessor-based signal processing with autoranging.
The concentration of a specified gas is displayed on a 4 digit, high resolution LED on the front panel.
The resolution depends on the gas mix, typically better than 100 ppm for hydrogen in nitrogen and 2000 ppm for oxygen in argon, with an accuracy of better than +/-2% of range.
A wide range of pre-programmed sample and reference gases can be selected using a simple front panel keypad and menu system.
Calibration settings for each gas mixture, stored in an internal memory, are recalled automatically when the mix is selected.
This facility allows the selected gas mix to be changed quickly and easily with the minimum risk of operator error.
Sample pressure and flow are internally controlled allowing connection to a wide range of pressurised sample sources.
The ultra stable katherometer and sophisticated signal processing provide a very fast response time - 90% of value within 20 seconds - combined with excellent stability and insensitivity to sample flow.
The Model 542 programmable gas analyser is supplied with auto zero and automatic timed calibration in an IP40 sealed steel case suitable for bench or panel mounting, plus an RS232 data interface, as standard.
Options include an IP55 sealed case, alarm contacts, 4 - 20mA analogue output and multipoint sampling.
Systech Instruments is one of the world's leading designers and manufacturers of gas analysis instrumentation and has agents and distributors in most major countries.
Systech gas analysis equipment is an essential part of the production process in many industries, including industrial gases, petrochemicals, pharmaceuticals, electronics and food, and is widely used by university and industrial research facilities.
