Best Natural Gas Alarms

Kidde Smoke & Carbon Monoxide Detector, Hardwired with Lithium Battery Backup, Voice Warning, 6-pack

Advanced technology – smoke and carbon monoxide detectors combine ionization & electrochemical sensors to detect invisible fire particles & CO gas.
Hardwired alarms with tamper proof backup battery – to help protect your home and family during power outages, eliminates the need for battery replacement.
Hush feature silences nuisance or “false” alarms – with just the push of a button on the alarm itself.
85-db alarm & voice warnings – “Fire!” or “Warning: Carbon Monoxide” so you know why the smoke & carbon monoxide detector is sounding.

...ibration function to adapts to new concentrations ..
{Visualization of leakage levels} The new upgraded LCD screen will display the leakage level of refrigerant gas. When the gas leakage are discovered, Will hear "di di" sound . More refrigerant leak, more rapid, meanwhile the indicator light flash quickly..
{Double-Alarms} The audible and visual display alarms in the leakage tester can easily help you to locate the leakage place. Once leakage is detected, the beep frequency will increase. The more gas leaked, the quickly the buzzer beeps, at the same time, the LCD screen displays the leakage level..
{Detecting All Halogenated Gases} It can detect all kinds of halogen refrigerants including CFCs, HFCs, HCFCs, HCs, HFOs and mixed refrigerants such as R11/R22/R404a/R410a//R1234yf/R134a and Blends such as AZ-50, HP62, MP39 etc. and response within 3 seconds. We offer 7*24 services and a one-year warranty for the gas leak detector..

Four-gas detector for surveying levels of H2S, oxygen (O2), carbon monoxide (CO), and combustibles in natural and industrial environments, and in other personal safety, training, research, and ambient air monitoring applications.
Electrochemical cell sensor measures H2S and carbon monoxide levels in ppm, capillary-pore fuel cell measures oxygen in percent by volume, and catalytic bead combustible sensor measures explosive gases in percent LEL.
Audio, visual, and vibration alarms alert simultaneously when ambient H2S, oxygen, carbon monoxide, and combustible gases reach preset low, high, TWA, or STEL levels.
LCD screen shows up to four ambient gas concentrations, battery level, alarm condition, and the status of calibration, bump, and sensor self-tests.
Integrated diaphragm pump allows for localized sampling of the atmosphere for more precise readings than those generated through diffusion.

【Visualization of leakage levels】The new upgraded LCD screen will display the leakage level of refrigerant gas. In addition, adjust the sensitivity by pressing the button, LCD screen will display sensitivity level..
【Multi-Alarms】The audible and visual display alarms in the leakage tester can easily help you to locate where the leakage is. Once leaking gas is detected, the beep frequency will increase. The more gas leaked, the quickly the buzzer beeps, at the same time, the LCD screen displays the leakage level..

CFCs, HFCs, HCFCs and blends from 100 ppm to 3000 ppm.
GOOSENECK PROBE 18-Inch for easy access around equipment.
VISUAL AND AUDIBLE alarms increase with refrigerant gas concentration.
DUAL LEVEL SENSITIVITY setting high (100 to 1000 ppm) and low (200 to 3000 ppm).
