The Formaldemeter is the perfect accessory to the Foramaflow Vaporizer range. The Formaldemeter htV-m can precisely measure formaldehyde concentrations in parts per million 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 Formaldemeter is reliable and simple to calibrate. The hand held device has a built in memory and real time clock enabling the htV-m to log all 3 parameters and corresponding times, allowing improved monitoring and analysis opportunities.

The Formaldemeter htV-m can also be used as a continuous monitor. A PC can automate the sampling and log data at specific times by a direct or wireless connection. All download software is supplied with unit.
