BIOS dry gas meter Defender220M

Shenzhen City Quest Technology Co., Ltd. Mr. Shi Han Bin:? 18814366140 BIOS dry gas meter Defender220H BIOS dry gas meter Defender220M BIOS dry gas meter Defender220L Bios Definer 220 Bios is the world's first choice for a small flow of gas flow calibrator product manufacturers. Its Definer series of products for gas flow calibration products brought epochal changes. Products using patented micro-friction between the piston and precision optical sensor, fast and accurate access to the test gas flow rate. The data obtained is the initial, can be traced, and its products meet the US NIST standards. Flow rate range of products from 5ml / min to 30l / min, with a compact, easy to use, automatic detection and other features, base accuracy from the field sampling different environment changes. Products can calibrate various gas flow meters, dust and biological sampling and a variety of pumps. Mainly used in semiconductor off, gas producers, various testing agencies. Model Flow range (min) 220L low flows for five ML - 500 ml 220M in traffic 50ml - five liters 220H High Flow 300 ML - 30 liters accuracy range: 1% of reading Gas compatibility: use of non-corrosive, non frost and difficult ene, humidity less than 70% of the gas flow pattern: suction pressure and suction temperature and pressure sensors: Pressure: 3.5mmHg (typical), 7.0mm (maximum) temperature: 0.8deg C (typical), 1.3deg C (max) AC Battery Charger: 220V switch 12V DC Reading mode: single cycle, continuous or pulse may be selected from 1-100measurements achieved a higher average value function.
