Product Details

The latest 3-parameter instrument 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.

  • 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 9001:2015 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.
  • Service centres throughout the world and full technical support provided under a comprehensive manufacturers warranty.
  • Bespoke solutions available for your specific application – contact our technical department.

FORMALDEHYDE SENSOR

Type Electrochemical manufactured
Range 0-10ppm as standard (0- 12.3 mg/m³ at 25°C).
Extended range available on request.
Resolution 0.01 ppm
Accuracy 10% at 2ppm
Precision 94% of all instrument readings meet the NIOSH criteria for an acceptable method when measuring 0.3ppm of formaldehyde over a relative humidity range of 25-70%. The NIOSH criterion for acceptability is that all results fall within ±25% of the true value at the 95% confidence level.
Calibration By user with supplied calibration standard or by original manufacturer.
