The K1550 range of analysers are ideal for measuring % levels of one  gas in a binary or pseudo-binary mixture. For example, air is composed  of many gases but in known, fixed ratios, therefore hydrogen in air is  a pseudo-binary mixture and can be measured with a K1550 hydrogen  analyser. 

Hydrogen analysis is well suited to this technique due to the high  thermal conductivity of hydrogen. Percentage levels of hydrogen  cannot be measured by a convenient dedicated sensor and so Hitech  katharometers provide a cost effective analysis solution. 

For hazardous area applications use the K1550FX. The sensor is  mounted remotely in the hazardous area and connected through an  MTL barrier to the electronics unit in a safe area. Alternatively, the  electronics unit can be supplied in an EExd enclosure with remote  keypad for non-intrusive calibration for full hazardous area use. 

A compensation input is available as an option, either fixed or variable via a  4-20mA input. This extends the capability of the analyser to measure the  hydrogen content in more complex mixtures. The KG1550 range also  features an integral oxygen sensor.

Hydrogen analysers are available with a choice of range. From 0  – 5% at the low end, 0 – 100% full range or 95 – 100% for hydrogen  purity applications. Multi-range instruments are sometimes available  on request and for specific applications. A completed application  questionnaire enables Hitech to provide a custom solution. 

 Different sample conditioning systems are available, standard or  bespoke, according to the process conditions. For corrosive gases a  variety of sensor assemblies and fittings according to the specific gas.  Eaton are ready to recommend complete systems on receipt of full gas  stream specifications.
