INTRODUCTION
This manual covers the K1650 & K6050 models of gas analysers designed specifically to
analyse the gas mixtures encountered when using hydrogen to purge alternator generators
and similar equipment. Carbon Dioxide is used to displace the air in the system, then Hydrogen
displaces the Carbon Dioxide. This ensures that Hydrogen does not mix with Oxygen and form
a potentially explosive mixture. Once filled with hydrogen the plant can be operated and the
analyser used to measure the hydrogen purity. The analysers are equipped with three ranges
so that each stage of the process can be monitored.
The K1650 comprises an electronic module and zener barrier mounted onto a sub-panel suitable
for convenient combined mounting.
The K6050 is a portable free-standing instrument with an integral sensor and packaged in a
rugged waterproof carrying case.
Common to both instruments is an advanced microprocessor based core, which provides a
fully featured, yet easy to use gas analyser. Gas analysis takes place using thermal conductivity
measurements made using a highly-stable, non-depleting katharometer sensor.
The K1650 is supplied with zener barriers to provide an intrinsically safe interface between the
sensor unit and the electronics allowing the sensor to be located in a hazardous area.
