VDA-03 Gas Density Relay Calibrator

Product Features

◆ 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 proportional 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 completed.

◆ It has a USB interface for easy export of historical data and system upgrades.
