The best gas detectors in comparison

EASY TO USE Switch on the gas detector in a clean air environment and wait for the beep signalling the detector is ready to use. Take the detector to the area where you want to check for gas leaks. If as soon as the internal sensor detects gas concentrations over 50ppm, the unit will indicate by illuminating the LEDs on the front of the detector and raise an audible alarm. The greater the presence of gas, the more LEDs will illuminate, and the alarm will sound more frequently.

FIREANGEL HOME PROTECTION In addition to our carbon monoxide detectors, we offer a wide range of other safety products designed to protect you and your family. Choose from smart and wireless devices, as well as standard fire, smoke, and heat alarms.

Accurate Measurement The gas leak detector adopts a high-performance sensor, which has the characteristics of high sensitivity, good reliability and fast response speed. The flexible metal hose and metal sensor shield of the gas leak detector can reduce interference

Multiple Detectable Gases This combustible gas detector possess good sensitivity, and long service life, it can detect methane natural gas,propane,ethane,butane,ethylene,propylene,butene,acetylene, butyne,phoshiphine,gasoline, sewer gas, and other flammable gases.

High sensitivity and wide measurement range, 0-9999PPM can be detected in "PPM" mode and 0% to 20% in LEL mode. Audible and visual alarm When the measured value is greater than 1.00%LEL, or greater than 500PPM, the gas leak detector will issue an alarm to remind the measurement personnel to pay attention

With one HP-5800G NH3 detector, you can simultaneously get the value of ammonia concentration and the current temperature and humidity to achieve highly efficient and comprehensive measurement.

The r134a leak detector features a new color graphic display that helps locate leaks using a unique bar graph mode to show the amount of gas detected and changes colors as it gets closer to the leak.

Accurate Relialbel CO Detector Comply with EN 50291 standard, CE Certified Carbon Monoxide alarm, equipped with high accuracy and reliable electrochemical sensor, continuously measure CO concentration in ambient air.

10-Year Lifespan Protect your loved ones from the silent threat of carbon monoxide for an entire decade with this reliable 10-year CO sensor; powered by replaceable AA batteries that last 3 years
