Automatic gas sampling device GSP-500FT 1 unit

Detector tubes designed specifically for indoor and work environments, as well as various solid collection tubes such as activated carbon tubes, can be used. The constant flow function automatically controls flow rate changes caused by load fluctuations. It has an automatic start function (time setting) and also automatically stops at the set time and volume. The suction flow rate, suction time, and total flow rate are displayed simultaneously, allowing you to check them at a glance without switching screens. Size (mm): 80 x 40 x 126 - Weight(g):280 Quantity: 1 piece Flow rate measurement range: Timer mode/50 to 500 mL/min, Constant volume mode/10 to 500 mL/min (for 10 to 49 mL/min, intermittent sampling at a suction flow rate of 50 mL/min) Accuracy of flow rate: ±5% (instantaneous flow rate of 50mL/min or more) Operating temperature and humidity range: Temperature: 0 to 40°C, Humidity: 10 to 90% RH (no condensation) Setting mode: Timer mode (Suction stops at the set time and displays the cumulative flow rate), Constant volume mode (Suction stops at the set volume and displays the suction time) Display: LCD digital display (instantaneous flow rate: mL/min, cumulative flow rate: L) Functions: Mass flow sensor (with temperature compensation function), with initial setting flow rate maintenance circuit, program mode Power supply: 2 AA alkaline batteries (included for testing) Accessories: Detector tube adapter, tip holder, 5 dust filters
