Description of Digital Portable Temperature Humidity Analyzer

MONITORING & ANALYSIS Allows continuous monitoring of CO2, RH & Temperature Level. Data output to PC every 2 seconds. MULTIPLE MEASUREMENT DISPLAYS AT ONCE- CO2, Temperature, and Relative Humidity readings are all shown on the LCD display at the same time. NORMAL/ MAX/ MIN/ AVERAGE (15mins/ 8hrs) MODE- It can show not only the normal, maximum and minimum CO2 readings but also the weighted average CO2 readings in the past 15mins (STEL mode) and 8 hours (TWA mode). AUDIBLE CO2 SOUND- The alarm beeps when the CO2 Level exceeds the preset value. The alarm threshold is adjustable. NDIR SENSOR for CO2 DETECTION- Non-dispersive infrared technology is used to ensure the reliability and long-term stability. Measures 0~9999ppm while 0~2000ppm can maintain a high accuracy at +/- 50ppm.

Good meter but takes up to 3 minutes to measure CO2.

I bought this CO2 meter to measure both the condition of the building and "other things" relevant in 2020. The meter appears to be accurate (fresh air is 425ppm, which is very close to the current global average of 400ppm). Some might find the gauge's UI a bit annoying, but anyone who's used a DMM will get used to it straight away - same idea with modal buttons. like most modern digital multimeters. It is important to know that the CO2 measurement seems to take about 3 minutes to set the value.

Pros
  • Testing, Measurement and Inspection
Cons
  • Requires an outlet

Air quality test results when eyes open under "face masks "

First, it works very well. Very sensitive and responsive to changes in nearby CO2 levels. face coverings. Outdoors, the CO2 concentration in the ambient air was around 500 ppm. I held the monitor to my nose and took readings from 1500 to peak around 2800 ppm. With a simply sewn fabric mask. I keep the monitor in the same place. the reading reached 9,999 ppm in a minute or two. This is the limit of the counter. The CO2 level was over 10,000ppm, I have no idea how high it was over 10,000ppm…

Pros
  • Industrial & Scientific
Cons
  • Large and bulky

Handy Air Flow and Air Quality Meter

I had an exhaust leak in my car I think. However, I have a very sensitive sense of smell and didn't want to spend a lot of time and effort trying to fix what may be a very small issue. I first tried a CO meter, but the meter itself was defective. Upon further investigation, I found that a CO meter wasn't what I needed anyway. Most modern cars don't emit much CO at all. The catalyst converts most of the CO into CO2 or water. Trying to detect CO also means detecting several parts per million…
