UEi Instrument CO71A Carbon Monoxide Gas Analyzer
The UEi CO71A is a handheld carbon monoxide detector with an electrochemical sensor that measures and alerts you both visually and audibly to the presence of dangerous carbon monoxide (CO) in ambient air. The UEI Test Instruments CO71A monitors carbon monoxide levels (0-999 ppm) in commercial and residential living spaces, warehouse operations, combustion engine repair facilities, public facilities and any other indoor areas where people may work or live.
- Preset alarms
- CO detection 1 to 999 ppm
- 3-color warning light
- Audible alert
- Max capture
- Data hold
- No auto shutoff
- One button auto zero
The LED light on the top of the CO71A carbon monoxide detector illuminates and changes colors based on preset CO threshold levels as indicated below:
GREEN: 2-9 PPM
AMBER: 10-34 PPM
RED: 35 PPM or higher
In addition, the audible alarm will sound if 35 PPM CO (or greater) is detected. The alarm frequency will increase with higher concentrations and when the alarm is sounding, the unit cannot be turned off.
The portable UEi test Instruments UEi CO71A carbon monoxide detector is easy to hold while moving around monitoring CO levels in different areas, but a holster and belt clip are included for hands free monitoring. Other features include a MAX button that will display the highest reading detected while the meter was on and a HOLD button that freezes the display with the CO reading at the time the HOLD button was pressed. The backlit display on the UEi CO71 is useful in dark environments to view readings and will displays BAT when the battery needs to be replaced. The meter does not include an auto shut off so will continue to monitor CO levels until turned off.
Carbon Monoxide (CO) - is a lethal poison produced when certain fuels are burned. It can rapidly accumulate even in areas that might appear well ventilated. Because CO is colorless, tasteless, odorless and non-irritating, it can overcome an exposed person without warning. Recognizing early warning signs of CO poisoning is sometimes difficult because early symptoms of CO exposure (headache, dizziness, nausea) are nonspecific and may be mistaken for symptoms of other illnesses and frequently produce weakness and confusion depriving a person of the ability to seek safety.
Exposure to CO: Important Numbers To Remember:
• 9 PPM Max allowable exposure for living area (ASHRAE standard)
• 35 PPM Max exposure for 8 hr work day (OSHA)
• 800 PPM Symptoms within 45 minutes - Death within 2 to 3 hrs
• 12,800 PPM Death within 1-3 minutes

UEi Instrument CO71A Carbon Monoxide Gas Analyzer
Honestly I’ve just takena shine to UEi stuff. I have their combustion analyzer and this meter is good to have for quick checks on CO safety. No complaints
Does its job
Small, compact, simple design that does its job at detecting CO and helping me identify locations of leaks.
Easy to turn on
This unit is easy to turn on, cycles through its check process and then is quick to getting the readings.
very easy to use co checker. it is very important to be aware if there is a co leak as most heaters and boilers are in confined spaces. i very much enjoy living so i always care this with me.
One of the best in the price range
This meter is great for the price. Solid and accurate. Don’t see a reason not to buy this one compared to the competition
Great CO detector
It has a price that no other CO detector can beat and the device seems to be of high quality to me however, it has a low quality case. The alarm isn't as loud compared to other detectors, but for myself I have no problems with it since I don't necessarily need a loud alarm.
Accurate Co tester
Accurate carbon monoxide tester good for home or professional use.
Got it for the price
Kept it for the performance. Uei is a bargain and the CO71a works great. The multi colored light helps ut a lot, helps get a great read on where the CO is. Much better than just a 'too much' alarm.
when working on any heater or boiler where carbon monoxide poisoning can be a possible issue i always make sure i bring this with me. I kinda like the yellow color as i think of this tool as my canary in the coalmine so to speak. pick one up if you dont have one already.
I don't know why, but most CO meters have a 2 year warranty. I want with Uei because theirs is 3. I'll take 50% more. The CO71a has been a work horse. I can't recommend it enough.
