GAO Tek Multi-Gas Analyser

Description Overview  GAO Tek multi-gas analyser is used for portable and rapid detection of toxic and harmful gas concentration, temperature and humidity measurement and exceeding the standard alarm. a 2.5-inch high-definition colour screen is used to display the concentration in real time, and gas. The main detection principles are electrochemical, infrared, catalytic combustion, Thermal conductivity, PID photo ion.     Features Waterproof, dustproof, explosion-proof, shockproof, and anti-static  Quick response with >10m sampling distance   Simultaneously detects 1-5 gases with flexible unit options  Offers three display modes, including real-time curves  Enhances linearity and accuracy  Automatic error identification, reducing human errors    Technical Specifications Detection range  0 ppm to 1 ppm, 10 ppm, 100 ppm, 1000 ppm, 5000 ppm, 50000 ppm, 100000 ppm, 200 mg/L, 100% LEL, 20%, 50%, 100%Vol, can be selected; and other ranges can be customised.  Resolution  0.01ppm or 0.001ppm (0 ppm to 10 ppm);  0.01ppm (0 ppm to 100 ppm),  0.1ppm (0 ppm to 1000 ppm),  1ppm (0 ppm to 10000 ppm or more),  0.01 mg/l (0 ppm to 200 mg/l),  0.1% LEL,  0.01%,  0.001% Vol  Detection principle  Electrochemical, catalytic combustion, infrared, thermal conductivity, PID photoionization, and so on, depending on the type of  gas, range, field environment and user demand.  Sensor service life  Electrochemical principle: 2 years to 3 years; Oxygen gas: 2 years or 6 years can be selected; infrared principle: 5 years to 10 years; catalytic combustion: 3 years; thermal conductivity: 5 years; PID photoionization: 2 years to 3 years.  Allowable error  ≤±2% F.S (other or higher precision levels can be customised)  Linearity  ≤±2%  Repeatability  ≤±2%  Uncertainty  ≤±2%  Response time  T 90 ≤ 20 s  Recovery time  ≤30 s  Power supply  3.7 VDC 6000 mAh high-capacity rechargeable polymer battery  Display mode  2.5-inch high-definition colour screen  Detection mode  Built-in pump-suction type measurement, and flow rate at 500 ml / min. Calibration flow rate should be greater than 500 ml / min, three-way pipe should be connected, so as to ensure that the excessive gas will be discharged from the bypass  Alarm mode  It is possible to set a sound & light alarm, vibration alarm, sound & light vibration alarm, and turn off the alarm.  Communication interface  USB (charging and communication), optional: RS232, infrared communication, automatic recognition  Data storage  Standard configuration is the data storage capacity for 100, 000 entries  Explosion-proof type  Intrinsically safe type  Explosion-proof mark  Exia II CT6  Standard accessories  Manual, qualification certificate, warranty card, USB charger (including the data cable), high-grade aluminium instrument case, belt clip, humidity dust filter  humidity  ≤10% RH to 95% RH   Protection level  IP 66  Working Temperature  -40 °F to 158 °F ( -40 ℃ to 70 ℃)  Dimensions  7.68 in x 3.03 in x 1.81 in (195 mm × 77 mm × 46 mm)  Weight  0.77 lb (350 g)
