Product Overview

The AQM-101 is designed to measure HCHO concentration, air temperature and relative humidity with visible and audible alarms. This HCHO monitor is an ideal instrument for indoor air quality (IAQ) diagnosis and HVAC system performance verification.

FORMALDEHYDE (HCHO) is a gaseous component of the earth’s atmosphere. The concentration of HCHO in natural ambient air is about 0.03 ppm. Formaldehyde is found in a number of products. While most of these products contain a relatively low amount of the compound, others have a fairly strong concentration of formaldehyde. This is particularly true with products used in the course of scientific research and other professions where tissue is preserved in some manner. Formaldehyde exposure can lead to side effects that range from mild to life-threatening.

Rated 1 out of 5 by RealUser from Very Basic. Not very useful. Logging doesnt include TWA or STEL. Software very limited. Chart colors are terrible, Dark Blue background not a good choice and cant be changed. Changing line color makes it hard to see numbers on the side of the table. Each reading is a dot and not a continuous line making it hard to track. The only mode that shows up on the chart is Real-Time and it stops showing once it reaches the max 32000 points (doesnt rollover). If you choose RollOver mode, it does not display on the chart. If you download the data you have to do it every time it reaches 32000 points (every 8.8 hrs at 1 second scan rate) and then make your own chart/graph. This would be a decent monitor if they put a little effort into the functionality.

Rated 3 out of 5 by Jason Gordon from Too Bad Ethanol Sets it Off Too! I bought these to detect formaldehyde outside of a fume hood in a lab space. Unfortunately it appears that this monitor detects the Methanol in the formaldehyde and not the formaldehyde itself. This is an issue because of the amount of Ethanol that we use of cleaning in our lab, these monitors were going crazy everytime Ethanol was sprayed and once the monitor was pegged it would take 30-40 minutes for it to return to normal levels. The monitor actually works really well but with our Ethanol use these are not practical in our lab.

Rated 4 out of 5 by pluto from Reliable reading and reproducibility We purchased this model instead of other cheaper versions hoping to get an industrial level accuracy and reliability for the reading. We are quite happy on the reading stability and reproducibility so far. Repeated measurements comparing with fresh outdoor air has been done and this meter has proven to be solid. Battery life is also quite good. On the other side, you would need a Windows computer to be able to do logging. The unit does not log anything internally. The meter not only responds to Formaldehyde. It also responds to, say, acetone, tested so far. I would recommend Omega to provide a list of VOCs this meter is also responding to, and the associated corrections need to be applied. Or simply put the options into the firmware. It is not easy to tell if you are actually getting response from Formaldehyde or it could be some other VOCs being measured. In some limited scenarios, you could associate with the actual smell to distinguish the actual gas you are dealing with. For example, if you are using acetone to do some cleaning, you know the reading is from Acetone.

AQM-101-HCHO-Monitor

Formaldehyde Monitor and Data Logger with LCD Display

Do this monitor require calibration, does it have a shelf life or can it be used indefinitely?

Does this product log all information - HCHO, Temperature and Humidity? Can you review all 3 results on Data Table afterwards?
