Features: 1. Waterproof, dustproof, explosion-proof, shock-proof, the circuit design, antistatic, resistance to electromagnetic interference 2. The built-in pump suction measurement, quick response and the sampling distance of more than 10 meters, special gas circuit design, can be directly detecting negative pressure and positive pressure - 0.5 ~ 2 kg gas, not influence the result of the measurement 3. 2.5 -inch high-definition color screen display, alarm, real-time concentration, time, temperature, humidity, storage, communication, printing, electricity, charging status, such as information, menu interface using high-resolution simulation icon displays the function of each menu name 4. Data recovery function, can be selectively restore or full recovery, wrong operation cause of trouble back at home 5. Automatic zero tracking, long-term use is not affected by zero drift. 6. Target multilevel calibration, linearity and precision of measurement, and can meet the national standards and local standards bureau of standard measurement at the same time. 7. The concentration of the calibration automatic recognition and prevent wrong operation, to avoid bad caused by human factors. 8. Can real-time detection or timing of measured gas (for the relatively small amount), when not in detection can turn off the pump to extend time. 9. Logging calibration, maintenance log, fault countermeasures, sensor life due to remind, the next concentration calibration time remind function Technical parameters: Detection of gas: ozone O3. Optional: can detect any 5 kinds of gas concentration and temperature and humidity Detection range: 0 ~ 1, 10, 100, 1000, 100, 1000 PPM Test principle: electrochemical, ultraviolet, semiconductor, Electrochemical principle of sensor life: 2 ~ 3 years, uv 5 years, semiconductor for five years Test method: built-in pump suction, flow 500 ml/min Display: 2.5 -inch 320 x240 high-definition color screen display, 8 keystrokes Accuracy: + / - 2% or less F.S (higher accuracy can be customized) Linear degrees: plus or minus 2% or less Alarm way: sound and light alarm, vibration alarm, visual alarm Response time: T90 20 seconds or less Recovery time for 30 seconds or less Working power supply: DC3.6 V Battery: 3.6 VDC, 5000 ma high-capacity rechargeable polymer battery Using the environment: temperature 40 ℃ ~ + 70 ℃; Relative humidity 0-99% RH or less Sample temperature: - 40 ℃ ~ + 70 ℃, equipped with cooling high temperature sampling filter handle or high temperature and high humidity flue gas concentrations of pretreatment system can detect 800 ℃
