Concentration measuring instrument 3-032-R003

chemical compositionelectronicSO2

Gas type : SF6 Standard version • measuring device for decomposition products with flowmeter and needle valve • safety valve • mounting for test tubes • DILO connecting couplings in DN8 and DN20 • tube opener • connecting piece with connecting hose • 2 spare O-rings • 2 m long flexible connection • transport case • operating manual For precise measurement During the operation of gas insulated switchgear, decomposition products might occur after a breakdown having a negative impact on the gas quality in the circuit breaker as well as on the insulation properties. For this reason the measurement of decomposition products is very important. The measurement can be carried out easily by means of test tubes and plastic bags. The following concentrations can be measured: • sulphur dioxide SO2: 1 to 500 ppmV • hydrogen fluoride HF: 1.5 to 15 ppmV • oil mist: 1 to 10 mg / m³ (0.16 to 1.6 ppmmass) Advantages & functions • The device is supplied in a handy plastic case. Gastight couplings DN8 and DN20 are also included in the scope of supply. Technical data Measuring principle : chemical reaction Dimensions (W x H x D) : 360 x 290 x 165 mm with transport case Weight : 2.4 kg without transport case
