This gas detector very easy to use and it works precisely. It tells you if there is a leak.

No. 3 x AAA 1.5V batteries need to be purchased separately.

The device will need around 10 seconds before you can start detecting gases.

 If the burner (the knob) is turned on, yes because gas is coming out. If the burner is off, then no. 

Yes, probe gas: Methane, natural gas, gas, propane, gasoline, ethanol, gas fuel, etc.

No. Only probe gas: Methane, natural gas, gas, propane, gasoline, ethanol, gas fuel, etc.

The sensor inside is mainly sensitive to Propane and Methane, the two components of LPG. The answer is yes, it can.

No! CO2 is not combustible.

Gas Sensitivity (adjustable): As low as 5ppm

It does not distinguish between different combustible gases, It only can find the location of a gas leak.

Yes, only if the septic gas consists of propane, butane, or methane.

The nature gas leak detector has a low power prompt function.The new battery can use 10-12 hours

Yes… the stronger the saturation the more lights and beeps.

Yes, someone actually asked us! So here is your answer: According to google’s result, farts are made of 59% nitrogen, 21% hydrogen, 9% carbon dioxide, 7% methane, 3% oxygen, and 1% others. So if farts are strong and lasting enough, this device can detect it!

This device is powered by 3 x AAA 1.5V batteries (not included)

It’s designed to detect gas leaks from a small location; We don’t see an issue with the basement; assuming you are tracing a gas line to see if there is a leak anywhere along with it. It is not going to detect a leak from “somewhere” in the basement just by sitting on a table for example.

1) Easy to understand video will be good choice, refer to “How and where to use the Y201 gas leak detector” around pictures area at beginning .

2) Get service support, engineers on staff from factory online will help to answer any questions related to leakage if above video can’t help to understand.

The design of ticking sound has two purposes: 

1) Indicates the device is working.For some cases, we need to extend the probe to the area that we can’t see LED lights, customers could judge thru the sound changes. The green power LED light is also used to indicate the device is working.

2) Represent different levels of gas leakage. Low frequency (around 2~3 times/s) means warm-up period or no leakage, if changed into high frequency (around 6~7 times/s) during detection process, means encounter leakage issue.

Notes: above is based on we set sensitivity well, because if we rotate the knob at anti-clockside too much, even there don’t have any leakage, all the 6 LED will be triggered on and sound will become piecing high frequency.

According to our experiment data at lab for different batteries brand, usually last from 15 minutes to 4 hours. Different brand batteries have very different quality. Indeed, the device is hungry for batteries. The sensor in the probe needs large power for micro burning process and we can feel a little warm if we use finger to hold the probe. Another reason maybe product itself, components (resistor, capacitor……) tolerance or damage on the PCB board may also lead to large power consumption, but the rate is very low.

Usually when we find customers from home inspection company, we will suggest purchasing rechargeable Li-batteries, because their technicians or plumbers use the device frequently and Li-batteries will help to save some batteries cost.

Don’t worry, it’s normal, the large moisture change and CO affect the sensor performance, and may lead to false alarm by 1~2 LED red bars, but only last for 1~3s (very short time) if we move probe away. If we encounter leakage along the pipeline or connectors, all 5~6 LED bars will be triggered on at one moment, light and piercing sound alarm will last at least for 6~8s.

Recommend 1~10cm, if too far, concentration will become smaller as distance increase from leak point, and maybe not enough find and locate tiny leakage.

Bubble is very good way and can be used to check all kinds of gas leakage while Y201 is mainly used for combustible gas. But for very tiny leakage and very strong leakage, bubble method maybe not good enough:

1) too tiny leak can’t blow up bubble, too strong will blow the liquid away and can’t have bubble,

2) some areas we can’t extend to apply bubble liquid,

3) need good luck and skills to control the bubble liquid concentration if DIY bubble liquid,

4) in some case, liquid contact may lead to equipment or device damage.

The best way is: use both methods for double confirm if allowed, since bubble is more visible.
