Brief introduction By adopting the method of solution absorption or activated carbon tube in acquisition environment and indoor environment formaldehyde, ammonia, benzene, TVOC, the harmful gas such as SO2, NOX, and also can be used for flue gas sampler. Is the environment monitoring, engineering quality supervision and health and epidemic prevention departments to collect all kinds of poisonous and harmful gas sampling tools, with functions of two-way constant current sampling, good stability and high accuracy. In Canada have larger load (connected to the pipe, activated carbon adsorption sampling tube), within the scope of the specification requirements of the traffic still can accurately display the real sampling flow rate. Features 1. Imported digital flow sensor, the instantaneous flow rate can be set up, the digital display, has the dual function of constant current sampling, sampling flow automatic control according to the set data sampling, constant current flow with high accuracy, sampling volume accurately 2. The operation is simple, quick time sampling function, small volume, convenient to carry. Sampling data automatic memory Settings, the next boot priority, a key to realize the sampling. 3. Unique drying, filtration, prevent breath triad of drying cylinder design, can effective dry gas, dust filter and breath reduce the influence on traffic, achieve long-term operation no clean. 4. Equipped with heater can be realized in low temperature environment sampling to realize constant temperature constant current function. 5. Made of imported brushless dc motor rotary vane sampling pump, stainless steel pump body, high suction negative pressure, flow stability, trouble-free running time is more than 10000 hours. 6. Automatic pressure and temperature before testing meter, automatic calculation and display the sampling volume and the volume. 7. Imported wide temperature OLED display screen, suitable for ultra-low temperature, low illumination conditions, Chinese menu display, illustrated, convenient operation. 8. The user can through the keyboard parameters of instrument calibration, maintenance need password to enter, to ensure the safety of instrument data will not be easily modify the error, and provide the function of the automatic restore factory Settings. 9. It can display real-time clock, dual sampling time, date, flow, pressure, such as direct display, data storage, 1000 group. 10.Ac/dc, built-in high capacity battery, continuous working time is more than 8 hours. Technical parameters Constant temperature, sampling flow: double road (0.100 ~ 1.000) L / 0.001 L/min min + 2% or less Sampling time: 1 min ~ 99 h 59min 1 min + 2 s or less Precision: 24 + 2 s Sampling method: two parallel samples or collect a single sample at the same time Working conditions: temperature (- 30 ~ 50 ℃; Humidity of 95% or less Working power supply: AC 220 v + 10% for 50 hz or DC12V (built-in) Noise: < 50 db (A) Power consumption: < 10 w The weight: about 4 kg
