Designed for personal protection. This instrument allows to simultaneously monitor pre-explosive concentrations (PEC) of flammable gases, maximum permissible concentrations (MPC) of toxic gases and required oxygen (О2) content in the air of working areas. Gas analyzer can have one or up to four measuring channels.
Compliance with industry regulations of JSC “Transneft”: “Air monitoring at facilities of oil and oil-products main pipelines “.
Application:
- environmental and labour protection services of industries related to emission of toxic gases into atmosphere;
- oil and gas processing and transportation;
- fuel and energy complex (FEC);
- tanks, holds and other rooms where lack of oxygen and presence of flammable and toxic gases pose a threat to human health or explosion hazard.
Gas analyzer type - portable (individual).
Sampling – diffusion or forced by means of exterior flow rate pump or rubber bulb.
