View Full SpecificationThe Hitech KG1550 gas analyser combines accurate measurement of oxygen in mixtures that contain another constituent suitable for measurement by thermal conductivity. Other gases measured include carbon dioxide, helium and argon, giving the analyser a wide range of applications in both food and process industries.
Oxygen is measured by an electrochemical cell that is virtually maintenance free. The oxygen concentration range can be from 0 to 100%, to 0 to 200ppm dependent upon the other constituents of the gas mixture.
The second gas is measured by a non-depleting, maintenance free katharometer thermal conductivity cell which combines high stability and low mass to form a sensor with fast response, high sensitivity and virtually no maintenance costs. By applying the power of a microprocessor to temperature compensation and linearisation, an accuracy and measuring range not usually associated with katharometers is provided. All suitable gases can be measured over 0 to 100%, with the maximum sensitivity being gas dependent, and ranges from 0 to 10% for carbon dioxide to 0 to 5000ppm for hydrogen.
Measured values are presented on a large, clear LCD screen which also displays messages and prompts for the menu-driven configuration and calibration routines.
Two concentration alarms are provided for each gas and give visual (LED) indication and volt-free changeover contact outputs. The user can configure the alarm function (high, low or off) as well as the hysteresis value.
The instrument is packaged in a standard DIN enclosure (96 x 144mm) with an optional locking cover with a rating of IP54.
For sampling, a variety of systems is available for any necessary pumps, filters and take-off tubes can also be supplied.
