MTL K1650 – Hydrogen Purity And Purge Gas Analyser
- Single remote sensor
- Measures all gas purge stages
- ATEX certified for hazardous areas
- Simple, low cost servicing
- Optional sample systems
- Easy replacement of old analysers
Description
The K1650 fixed analyser consists of display /controller unit, pre-mounted in a panel for easy retrofitting and a remote sensor assembly. The remote sensor assembly consists of a katharometer supplied in a wall mounting, IP65 enclosure complete with flowmeter and sample flow control valve. The sensor is certified to European standards for use in Group IIB + H2 gases, and the zener barrier interface, incorporated in the display/controller unit, allows ‘live-working’ on the sensor unit.
