2. Designation
Portable explosion-proof gas analyzers PGA-ESP "BESTia" are designed to measure the
concentration of flammable gases by volume fraction of oxygen, sulfur dioxide, nitrogen dioxide,
nitric oxide, hydrogen sulfide, carbon monoxide, chlorine in the air of the working area and signaling
when threshold values are exceeded.
The gas analyzer is an automatic device for personal protection of continuous operation.
Features and benefits
•
Determination of gas concentrations vital for humans in the working area;
•
User friendly screen interface;
•
Application of 4 types of sensors at the same time to obtain data on -
o
measuring channel for combustible gases - infrared, thermocatalytic;
o
measuring channel of oxygen, hydrogen and toxic gases - electrochemical;
o
measuring channel LEL hydrocarbons - photoionization.
Field of application
PGA-ESP gas detectors are available in explosion-proof design and can be used in hazardous
areas of buildings and in open facilities in accordance with the explosion protection marking of the
device and regulatory documents governing the use of electrical equipment in hazardous areas.
Tables No. 1, No. 2, No. 3 and No. 4 show the conversion ranges and the limits of the
permissible basic error of the gas analyzer for all types of sensors used.
