VDA-03 Gas Density Monitor Calibrator

The instrument adopts a dual gas path design, supporting two types of gas supply methods: external gas cylinder and internal gas pump.
The instrument is equipped with a high-performance pro- portional valve, and the calibration rate can be adjusted automatically according to the parameters of the calibrated instrument.
It supports the calibration of various gas types of instruments,including pure SF₆, SF₆/N₂ mixed gas, and SF₆/CF₄ mixed gas.
The output voltage supports 24VDC and 110VDC voltage out， and has the function of measuring contact resistance.
It supports zero pressure and working pressure calibration methods.
The product is equipped with a 7-inch color touch screen for easy observation and operation.
It is equipped with a complete set of transition adapters, so that most models of switches' density monitors can be field-on-site calibrated without disassembly.
The engineering plastic case is beautiful and durable, with a high protection level.
It is equipped with a large capacity memory, and the calibration data can be stored for a long time.
It is equipped with a high-speed micro thermal printer, which can print the calibration results after the calibration is complet- ed.
It has a USB interface for easy export of historical data and sys- tem upgrades.
