bios piston gas flowmeter Defender520M

Shenzhen City Quest Technology Co., Ltd. Mr. Shi Han Bin: 18814366140 Defender510 / 520/530 gas flow calibrator details Defender 510/520/530 is a new generation of dry gas flow meter, which is the level meter, and a large number of personal sampling pump manufacturers recommendations 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 * Choose the volume flow rate adjustment criticize the standard state of the internal leak * self-test function for each reading time from 1 to 15 seconds reading mode (select measuring from 1 to 100 times average) Single (manual), continuous or burst mode gas No corrosive gas compatibility, non-condensing gases, humidity less than 70% of the flow pattern measuring pressure or suction unit integrated AC AC to DC converter / battery charger 12V DC,> 250ma, 2.5mm center position Battery System Battery Type 6V rechargeable sealed lead-acid battery, the typical operating time of 6 to 8 hours battery run time (5 times / min) backlight open three hours, the backlight is off 8 hours pushed or suction hose attachment operating pressure (absolute) 15 PSI graphic LCD display with backlight liquid crystal display data port (using optimization software) RS-232 serial data cable (using optimization software) 1m Defender Calibrator to the computer's serial port size ( H x W x D) 140x150x75mm Weight 820g
