PPM - Model htV - 3-Parameter Formalde Meter - Operation Manual

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.
