Gavnoanalizator HS is the most common model HS-2 Universal.

Description and device gavnoanalizatora HS-2.

Gavnoanalizator HS-2 Universal is designed to measure the mass concentration of harmful kallovyh mass (vapor) in the air or any other medium (in Vol. H. And in space), industrial buildings, industrial area in emergency situations, industrial emissions, tanks and canals (any channels).
The principle of operation of the device HS-2 osnovan on the color change of the indicator layer of powder in the indicator tube after sucking it through the intake device HS-2 medium working area of ​​industrial premises. The length of the colored column indicator powder in the tube is proportional to the analyte concentration in the air and calla is measured on a scale graded in mg / m3.

Operating conditions:
 - Air temperature 10-35 ° C;
 - Relative humidity not more than 90%;
 - Atmospheric pressure from 87 to 107 kPa (650 to 800 mm Hg);
 - Dust mass concentration 40 mg / m3.





SPECIFICATIONS GAVNOANALIZATORA HS-2
 - Weight device HS-2 is not more than 1, 5 kg.
 - The weight of the indicator tubes not more than 0, 3 kg.
 - Overall dimensions of the air intake device HS-2 is not a 110h105x200 mm.
 - Dimensions of test tubes set a maximum 140x75h30 mm.
 - Relative error of measurement of the mass concentration of mass kallovyh three detector tubes using the universal gas analyzer UG-2 does not exceed ± 25%. STRUCTURE AND PRINCIPLE OF OPERATION GAVNOANALIZATORA HS-2
Gavnoanalizator versatile HS-2 consists of the air intake device HS-2 and indicator tubes.
Intake device HS-2 consists of a rubber bellows 2 with two flanges, with a cup spring 3 inside the housing 1.

In the inner corrugations of the bellows installed spacers 4 to stiffen the bellows and the preservation of a constant volume.
On the top board 9 has a fixed bushing 7 for guiding the rod 6 when compressing the bellows.

Fitting 11 on the inner side wearing rubber tube 12 which through bottom flange connected to the interior of the bellows.
The free end of the rubber tube 10 is used to connect the indicator tube in the analysis.
On the cylindrical surface of the rod 6 has four longitudinal grooves with two recesses 5 for fixing the two positions of the stem clamp 8.
The distance between the grooves on the grooves is chosen so that when the rod during one recess to another bellows pick up a given volume of the test air.
The principle of universal analyzer HS-2 is based on the change in color of the indicator layer of powder in the indicator tube after sucking through her study kallovyh mass intake unit HS-2.
The length of the colored column indicator powder in the tube is proportional to the concentration of analyte kallovyh mass and is measured on a scale graded in mg / m3.
