Variants of climatic versions: ТМ3 (export).
In case parameters of gas mixture at gas analyzer inlet do not coincide with the ones given above, sample preparation unit БП-1-А or separate auxiliary devices (cooler ХК-3А (ИБЯЛ.065142.005), frigistor-А(ИБЯЛ.418316.016), safety valve ИБЯЛ.301122.044, fine adjustment valve ВТР (ИБЯЛ.306577.002-04)), that are supplied on separate order, can be used.
Functional capabilities:
- digital indication of measured component content;
- 4 alarm thresholds;
- commutation of external circuits by one group of switching relay contacts upon alarm actuation;
- output of data on measured components concentration through current output of 0-5 or 4-20 mA (switchable) and via RS232.
