The Biogas Analyser 905 monitors either continuously
or intermittently, the gas components contained in the
Biogas and optionally, monitors the surrounding air to
provide an early warning of dangerous, explosive and
non-combustible gases and vapours.

Features:

Up to 5 sensors for Biogas measurements

Up to 3 sensors for room monitoring

Time-controlled measurements in intermittent mode

4-line display, each line with 16 characters

Menu-assisted operation via 6 keys

16 freely configurable alarms (max. 3 per measurement point or sensor)

Adjustable alarm threshold, from 5 to 100 % of the measurement range

A minimum of 5 floating alarm contacts for optional assignment

Floating service and fault contact

5 analog outputs, 4-20 mA

5 digital inputs for control functions (initiating a measurement, selection of a measurement point)

Double measurement change-over switch in the standard housing (optional); extras by request

Serial output RS 232 or RS 485

Manual flow-through adjustment

Gas components-filter system and conditioning

Condensate collector for external installation

High degree of operational reliability

Low power consumption
