bios gas flowmeter Defender520L

Defender510 / 520/530 gas flow calibrator details Defender 510/520/530 is a new generation of dry gas flow meter, which is a flow meter, and a large number of individual pump recommended by the manufacturer and supporting the use. It can be used for industrial hygiene, environmental protection and various laboratories. It uses the principle of a dry piston movement, one button to generate a plurality of consecutive readings. Compared with the traditional foam-type flow meter, easier to use and fast. 520 models tested simultaneously increasing the temperature and pressure capabilities than 510. Features: a primary standard, NIST traceable unit · displays of: mL, L, cc, cfm · Accuracy: ± 1% · Continuous automatic measurement, can quickly and easily adjust the air flow velocity Automatic calculation of mining multi-point average value, up to 100 data Gan graphite piston design, no soap bubble solution, measuring rapid ? When suspended, automatically shut down within five minutes the power saving function to save battery power · pressurized intake or exhaust all negative Measurable Can be connected to a PC to download the corrected data results * Optional transfer criticize the volume flow rate under standard conditions * With self-test function internal leak Defender510 / 520/530 select different models to meet different customer needs.
