Now available from Alvi Technologies , the ADT 53 1197 hydrogen sulphide emission monitor is ideal for monitoring the operation and efficiency of H2S scrubbers used in odour control systems.
Odour control systems treat foul air coming out of water, waste water and sewerage treatment plants. H2S or hydrogen sulphide is a toxic and flammable gas that has the smell of rotten eggs and is the key contributor to odour emissions from these treatment plants.
In odour control systems, H2S scrubbers use activated charcoal or carbon to dull these odour emissions. To monitor the operation and efficiency of these scrubbers, hydrogen sulphide monitored in the inlet and outlet side. While the inlet side will have a higher parts per million concentration of hydrogen sulphide, typically the outlet side will have a nil, or very low, concentration.
The ADT 53 1197 hydrogen sulphide emission monitor from Alvi Technologies works on 24 VDC, 2 wire and gives out 4-20 mA output and comes in ranges 0-50 ppm H2S, 0-200 ppm H2S, 0-1000 ppm H2S or 0-5000 ppm H2S.
These hydrogen sulphide emissions monitors comes with an in-line sampling kit. The 4-20 mA output can be connected to a MGC-03 gas controller for concentration readout, 4-20 mA output for PLC, SCADA, and to generate alarms signifying filter or scrubber breakthrough or saturation.
