Description Overview GAOTek Fast Response Hydrogen Cyanide Meter is single gas detector and easy to take. It is intrinsically safe instrument that can continuously detect the concentration of combustible gas and toxic gas. The gas detector is widely used in municipal emergency rescue, oil chemical industry, metallurgy, coking, environmental protection, and other industries. It has OLED display, self-Illumination, wide perspective, high brightness, and resolution. People can read display clearly five meters away. It can collect gas data and save data automatically, and then transfer the data to computer. Features Big OLED display, Highlighted, High definition Automatically save the detecting data for 5000 records Data progress bar display mode Can learn the state of concentration Low power consumption, save energy, save electricity Real-time clock display function The key operation needs to input a password to prevent misuse Automatic calibration function reduces the measuring error. Recover key data, avoid the loss of data Battery power real-time display Under-voltage hint and low-pressure Standard MINI-USB charging port The charger is compatible with compute Charging protection function Computer connection function; to sync data Alarm type: Sound, light, Vibration alarm STEL and TWA alarm function for toxic gases Power on self-test function Adjustable high and low alarm level Replaceable modularized sensor Technical Specifications Detected Gas HCN Measuring Range 0 to 20 ppm Resolution 0.1 ppm Respond Time ≤ 30 s Sensor Service Life 2 years to 3 years Sampling Method Diffused or pump suction (external electric sampling pump) Deviation ≤ ± 3 % FS Working Humidity < 95 % RH no condensation Display Mode OLED screen shows density, time, battery power, alarm state, percentage progress bar Data Storage 5000 records Upload Data Connected to computer via data cable Working Voltage DC 3.6 V lithium-ion battery, 1 Ah (1000 mAh) Charging Time 4 hours to 6 hours Working Time Combustible gas > 8 hours (continuous); Toxic gas > 72 hours (continuous) Protection Class IP 66 Temperature Toxic gas, oxygen: -4 °F to 122 °F (-20 °C to 50 °C) Combustible gas: -40 °F to 158 °F (-40 °C to 70 °C) Dimensions 3.85 in × 2.36 in × 0.94 in (98 mm × 60 mm × 24 mm) Weight 0.31 lbs.
