Two different models of formaldemeter available:


Formaldemeter™ htV

The latest 3-parameter instrument directly measures airborne formaldehyde concentrations as well as ambient temperature and humidity levels.  The htV can now accurately measure low levels of formaldehyde — even in humid conditions — while still maintaining ease of use and simple calibration.



  • Displays formaldehyde concentration in both parts per million (ppm) and mg/m³
  • Immune to extremes of humidity and temperature thanks to a unique sampling method
  • Simple calibration procedure can be carried out in a few minutes after only minimal training – the full kit contains a field calibration standard (6 months shelf-life) and a comprehensive operation manual
  • Fast sampling by pressing a single button and quick recovery from normal concentrations
  • Manufactured to ISO 9001:2000 quality standards and compliant to CE regulations
  • Full range of accessories available including rear stand or wall mount for hands-free operation and PC remote control software for data logging. See separate brochure for more details



Formaldemeter™ htV-M

The Formaldemeter htV-M offers the same precise 3 parameter monitoring for low levels of hazardous formaldehyde vapours under extremes of temperature and humidity as seen in the Formaldemeter htV but with the addition of these impressive extra features:



  • A built in non-volatile memory that can be upgraded
  • Capable of up to one month of continuous monitoring
  • A real time clock
  • Built in alarm
  • Mains or battery powered
  • Can be used as a manual hand held and a continuous monitoring data logger
  • USB interface allowing direct connection to PC for data download or control by the SPC-3 programme without the need for additional hardware
  • Supplied with the htV-M download software
  • Manufactured to ISO 9001:2000 quality standards and compliant to CE regulations
