Formaldemeter htV

The 3-parameter Formaldemeter htV 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.

Applications:

·       Medical Care & Sterilization

·       Pharmaceuticals

·       Agriculture

·       Fumigation

·       Paint and Paper manufacture

·       Textiles & Dye manufacture

·       Particle & Laminate Boards

·       Building Management

·       Air Conditioning system management

·       Environment and Public Health Agencies

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 9001:2000 quality standards and compliant to CE regulations.

FORMALDEHYDE SENSOR

Type: Electrochemical manufactured by PPM Technology.

Range: 0-10ppm as standard (0-12.3 mg/ m³ at 25^๐C). Extended range available on request.

Resolution: 0.001 ppm

Accuracy: 10% at 2 ppm

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.

TEMPERATURE & HUMIDITY MODULE

Type: Interchangeable digital CMOSens®

Range: -40 to +128^๐C, 0-100% RH

Accuracy: +/-0.4^๐C, +/-3% RH Optional upgrade to +/-0.3^๐C, +/-1.8% RH

Calibration: Calibrated to ISO/IEC17025 by manufacturer. Traceable by the ‘National Institute of Standards and

Technology’ and the ‘National Physical Laboratory’.
