The latest 3-parameter instrument from PPM Technology directly measures airborne formaldehyde concentrations as well as ambient temperature and humidity levels. Building on the technology developed in the popular Formaldemeter 400, with the addition of unique compensation techniques, the htV can now accurately measure low levels of formaldehyde — even in humid conditions — while still maintaining ease of use and simple calibration.
With further importance being put on air quality in public buildings, the workplace and in homes, the htV is aimed towards being the most accurate monitor while still providing quick and simple operation from a hand-held device.
