PPM - Model htV-M - Formalde Meter -Operation Manual

With the subject of Indoor Air Quality becoming more prominent and recognised throughout many different industries, it has become essential to be able to accurately monitor low levels of indoor pollutant gases.  The htV-M can precisely measure formaldehyde concentrations in parts per million (ppm) and mg/m3 over a wide range of temperature and humidity. Fast and easy to use, pressing a single button gives an immediate indication of concentration levels. The improved Formaldemeter htV-M is reliable and simple to calibrate. The compact size means the htV-m is small enough to be used as a hand held device.
