This portable Formaldehyde (HCHO) datalogger meter measure folmaldehyde concentration in air. Formaldehyde is one of the most commonly poisonous substances found in daily life and industry. This item also measures temperature and humidity. Designed with electrochemical accurate HCHO sensor that measures up to 5ppm. It has wide LCD display with backlight function and audible alarm.


With the touch of a button, the meter displays TWA8hr, STEL15min and one hour (1Hr) weighted average for occupational monitoring.


Wide Range of Application:

  • Indoor air quality inspection
  • Air quality research
  • Manufacturing
  • Phamaceutical
  • Medical
  • Food
  • Cleaning
  • Synthetic resins
  • Textile treatment
  • Horticulture
  • Cosmetics and many more
