Y201 Combustible Gas Detector Manual
※
Before use of this product, please read the instruction manual carefully.
General Instructions
Yeezou 201 combustible gas detector (hereinafter referred to as
“
detector
”
) has a high-
performance semiconductor gas sensor with excellent sensitivity, used for detection of leaking
combustible gases such as natural gas or propane in households, factories, hotels, apartments,
and other areas where gas leak localization is desired.
The detector is powered by 3 AAA batteries (not included). The hand-held portable design allows
you to check for gas leaks almost anywhere. The visual LED and audible alarm notify user of
presence and relative concentration of combustible gases. The varying audible ticking rate and
number of lit LEDs help a user determine the rate of gas leak. The quick response sensor bulb
with varying sensitivity dial allows detection of leaks both large
and small.
Important Notes
To avoid damaging the sensor’s molecul
ar membrane from overpressure, never use test gas
sources with directed high pressure (such as from a gas pressure nozzle) to do a gas leak test. We
suggest turning on and off a lighter or gas stove to leave gas in the air, then subsequently moving
the detector probe to the gas area to check functionality.
Test use of ultra-high concentration of combustible gas may reduce usability of the detector and
also lead to a flammable hazard.
