Acetyl Chloride is colorless, fuming liquid with a pungent odor. It is high flammable, water reactive and air reactive chemical. Acetyl chloride is a reagent for the preparation of esters and amides of acetic acid, used in the derivatization of alcohols and amines.

Acetyl Chloride vapor irritates mucous membranes. Ingestion of liquid or contact with eyes or skin causes severe irritation

SMART S series acetyl chloride gas or vapour sensor transmitter is highly robust, industrial grade, flameproof or explosion proof instrument for LEL concentration detection. The instrument can be installed for flammability level or LEL detection of acetyl chloride vapour or leakage in all industrial and commercial area eg. chemical plant, solvent manufacturing unit, polymer industry, manufacturing plants, warehouse etc

The detector can be installed at walls, surfaces or in ducts for monitoring in gas or air sample. It is ATEX EEx’d’ certified with SIL 2 safety integrity level for hazardous area installation Zone 1 and 2.
Explosion proof or flameproof gas sensor transmitter - ATEX, Zone 1, 2 for all toxic, flammable gas, oxygen
The sensor transmitter offers linear, proportional analog output in industry standard current signals, over measuring range of 0 ~ 100% LEL (lower explosive limit). The detector works on highly sensitive catalytic bead based pellistor sensor cell, with low response time. It has unique feature of auto diagnostic watch dog with zero point tracking feature. Due to its 10-bit microprocessor based control unit, it offer high accuracy over long term. The detector is also equipped with sintered filter with flashback arrestor for enhanced safety.
