Programmable alarms and analogue output
Maintenance free sensor
The Hitech K1550 accurately measures the changes of one constituent in binary or pseudo-binary gas mixtures (ie, mixtures in which only one constituent changes). Examples include hydrogen, carbon dioxide, argon, helium and various halogenated hydrocarbons such as the Freons. Almost any single constituent of a gas mixture can be measured providing its thermal conductivity differs from that of the other components. Ranges from high ppm to 100% are possible depending on the gas being measured.

A katharometer sensor measures the thermal conductivity of the gas. The sensor incorporates a highly sensitive, non-depleting element of low thermal capacity, which requires no maintenance. Signal processing and temperature compensation are provided by a microprocessor to give a level of accuracy and a range not normally associated with this type of sensor. Little or no calibration is required because of the system’s inherent high stability.

Measured values are presented on a large, clear LCD which also displays messages and prompts for the menu driven configuration and calibration routines.

Two concentration alarms provide visual (LED) indication and volt-free changeover contacts. They are user configurable for function (High, Low or Off) and hysteresis value.
