When analyzing gases dissolved in transformer oil using the ARP method (equilibrium vapor analysis), mixing of the contents of the syringe with oil is used to accelerate the extraction of gases (to achieve an equilibrium distribution of gases dissolved in oil between the liquid and gas phases). For this purpose, as well as automation of the mixing process, a special autonomous device for achieving equilibrium is produced. technical specifications The rotation speed of the syringe drum is 30 rpm./min. The rotation time (determined by the internal timer, after pressing the "Start" button) is 10 minutes. The number of syringes placed is 4. The volume of syringes is 20 or 50 ml. Power consumption, no more than — 14 VA. Overall dimensions, no more than 210×280×270 mm. Weight, not more than — 5 kg.

The flow regulator consists of the following parts: Body. It includes a connector for connection to the control controller and fittings for connecting the input and output gas lines. Calorimetric converter. Due to the heating of the gas along the flow section, the temperature difference is determined. The actuator (solenoid valve). The control board. A system of elements responsible for converting the signals that the user submits. TECHNICAL CHARACTERISTICS OF RD The gas pressure at the inlet is (0.4 + 0.04) MPa. Ranges of working gas flow rates — from 5 to 800 ml/min. The ability to specify the type of gas (nitrogen, helium, hydrogen, argon, air). Pressure ranges — from 0.001 to 0.40 MPa with a discreteness of 0.0001 MPa. The deviation of the carrier gas flow rate from the average value is + 1.5% in the flow range from 50 to 100 ml/min and + 0.5 ml/min in the flow range from 3 to 50 ml/min. Relative deviation of the average steady-state gas flow rate from the set value in the range from 3 to 100 ml/min: + 2.5%, but not less than 0.5 ml/min; from 100 to 200 ml/min.: + 5%; from 200 to 800 ml/min.: + 10%. The gas pressure at the inlet is (0.4 + 0.04) MPa. The deviation of the regulated output pressure of the regulator from the set value is not more than 1%.

The FGH-1-2 chromatographs have retained the main advantages of the FGH-1 model – mobility and ease of operation and maintenance. At the same time, FGH-1-2 has all the advantages of a modern multichannel chromatograph – the ability to reliably identify and accurately determine the concentrations of various pollutants of environmental objects. The additional use of automatic identification in the processing of chromatograms simultaneously through both channels makes FGH-1-2, in fact, a universal selective gas analyzer of organic substances using the chromatographic separation method. In FGH-1-2, as well as in FGH-1, all methodological problems have been solved: all measurement methods (MI) used are certified, the devices are equipped with sampling devices prescribed in MI, the devices are graded according to the required substances, independent control of the stability of calibration characteristics and measurement errors is provided.

The PA-1 single-channel portable aspirator is based on the PC-1 portable compressor. It provides air aspiration with a flow rate from 0.1 to 0.8 l/min. The aspirator is powered by an integral battery.
