## Description

ADKS-4 Portable Gas Detector, 4 Gas Monitor H2S,O2,CO and LEL Multiple Indicator with Vibration, Audible, Visual 4 Gas Monitor Personal Rechargeable Gas Sniffer Alarm with LCD: desertcart.com: Tools & Home Improvement

Review: A must have safety device for your house or work-shop/work-place - Portable multi-gas monitors are vital in protecting you from the hazards of toxic and combustible gases in confined spaces and dangerous work environments. Typical four gas monitors use an explosive meter multi-gas detector to detect combustible gas (methane, LPG, hexane, propane), carbon monoxide, hydrogen sulfide, & oxygen deficiency/enrichment. Other multi gas detectors are available to detect other specific gases, such as ammonia, chlorine, ethylene oxide, ozone, phosphine styrene and sulfur dioxide. This particular model however, will focus on those four essential but dangerous gases: H2S, O2, CO and LEL. LEL: Stands for “Lower Explosive Limit” and is the lowest concentration of a particular gas that has the potential to be flammable or combustible. In other words, it’s the minimum amount of gas that will catch fire or explode when an ignition source is present. If a gas concentration is less than the lower limit, there is insufficient gas for the mixture to ignite. O2: Oxygen gas detectors will typically trigger an alarm when the oxygen level drops below 19.5 percent volume. The most common use of oxygen gas detection is in confined spaces, totally or partially closed areas not designed to be permanently occupied. CO: This is a poisonous, colorless and odorless gas that interferes with the blood’s ability to carry oxygen. Under normal operating conditions, well maintained and correctly ventilated gas appliances produce minimal CO, but high CO levels can occur if one or more of the following conditions exist: An appliance is faulty or poorly maintained. A flue is partially or totally blocked. The appliance is not installed in an adequately ventilated area. H2S: Hydrogen sulfide (also known as H2S, sewer gas, swamp gas, stink damp, and sour damp) is a colorless gas known for its pungent "rotten egg" odor at low concentrations. It is extremely flammable and highly toxic. As you see above, having this multi-gas detector could be a life saver in some situations. This particular model comes with a storage/transportation hard shell/case, along with its user manual and a Mini-USB to USB charging cable. It’s well build, rugged and also waterproof, which is great. It provides visual, audible and physical (vibrations) alarms, which you can’t miss in case of an emergency. Whether in a refinery, petrochemical or wastewater plant, or perhaps a warehouse or even your house (if you live in Ohio lately), it’s crucial to have a reliable gas detection system you can depend on. With nationally recognized hazardous area certifications, this multi-gas detector is guaranteed to safeguard your facility or your home.
Review: Detector de gas - Good quality 4-gas detector. Easy to use, accurate readings, and loud alarms. Works perfectly and feels durable. Great value for the price. Highly recommended.

### ⭐⭐⭐⭐ Gas Meter
*by S***S on November 29, 2025*

This is a nice little gas meter. I use meters at work- and am familiar with the professional grade 4 gas meter which this is emulating. This meter is decent. It detects oxygen, H2S, carbon monoxide, and 10% LEL of flammable gases. It is lightweight, rechargeable, and decently priced. I tested the meter by exposing it to car exhaust- it alarmed both visually with lights and audibly with an annoying beep for both CO and low oxygen environment- which would be expected. I also tested it with butane- which did not alarm, but I don't think I had enough concentration to make 10% of LEL. I don't have a source of H2S to test it, as it does not come with a calibration gas cylinder. From what I could test- it functions well. I like that it comes with a clip so that you can wear it on your belt or shirt when working in an environment such as a confined space that may have gas or low oxygen. It also returned to normal quickly when removed from the gas environment. I would not use this type of meter to pinpoint leaks as much as to test the safety of the air in an environment. A meter with a wand would be better for specific leak detection. While this will tell you that there is a presence of methane or propane (or any flammable hydrocarbons) in the area, it may not be specific enough to pinpoint the leak. It serves the purpose of a warning- if this is alerting- you need to be exiting the area to fresh air and calling a professional. Some things I don't like about this detector are the lack of a battery meter- I didn't see any way to know how much charge was left. The instructions were not great- and obviously poorly translated. I attached a photo of one page that actually says that they are purposely NOT including instructions on calibration as that is for professionals? Well as a professional- one still needs instructions to be able to perform calibration on this specific meter. It suggests to calibrate every so often- at least once a year- but with no included calibration gas- and no instructions, I'm not sure how they expect anyone to do that. While calibration gas kits are usually sold separately, there is no mention of which kit specifically this meter uses- or if one exists. There also doesn’t appear to be a way to perform a fresh air calibration (zeroing the sensors), nor any method to perform a bump test to confirm sensor response. Overall, this is a nice safety device for the individual. I do not think it is a professional grade meter like a hazmat team would use- but it is useful in the industrial setting or even at home to monitor the air for the presence of some of the top hazards. Anyone working with potentially dangerous environments should have something like this. Just be aware that without calibration gas or detailed instructions, long-term reliability may be limited. Still, for a quick check or added peace of mind in a potentially hazardous environment, this device is a worthwhile and inexpensive tool.
