Description Overview This portable gas detector offers outstanding performance for continuously monitoring Hydrogen Cyanide (HCN). Its most striking feature is a large, high-definition OLED display, which is self-illuminating and provides a crystal-clear reading with a wide viewing angle, even from a distance. Engineered for extended use, it boasts an impressive battery life of over 72 hours of continuous operation. The device automatically saves up to 5000 data records, which can be easily transferred to a computer for analysis. With user-friendly features like password-protected operation, automatic calibration, and a replaceable sensor module, this compact and intrinsically safe detector is a reliable and low-maintenance choice for industrial and emergency rescue applications. 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 Specification Description Detecting Gas CL2, or combustible gas, toxic gas, oxygen Measuring Range 0-20ppm Sampling Method Diffused or pump suction (external electric sampling pump) Deviation ≤± 3% F.S Respond Time T90 < 30 s Working Temperature Toxic gas, oxygen: -20 ℃ ~ 50 ℃<br>Combustible gas: -40 ℃ ~ 70 ℃ Working Humidity < 95% R.H. no condensation Sensor Life 2-3 years 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 line (optional) Alarm Type Light: wide-angle light emitting diode<br>Sound: 90 Db humming; when concentration increased, frequency increases<br>Vibration: oscillator speed of 1300 r/min Working Voltage DC3.6 V lithium ion battery, 1000 mAh Charging Time 4 h ~ 6 h Working Time Combustible gas > 8 h (continuous); Toxic gas > 72 h (continuous) Protection Class IP66 Weight 140 g Appearance Size 98 mm × 60 mm × 24 mm
