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.
