Record and log relative humidity,
temperature & CO2 readings and graph data on your PC
Features & Applications:
Poor air quality cannot only affect ambient air, but result in
decay or damage to a structure. Equipped with infrared technology
to accurately measure these components. Measure RH, temperature
and CO2 with precision-enabling you to assess the conditions
in the test area.
Designed for residential and commercial applications, it also has
the ability to calculate and display cfm/person ventilation rate-hence
identifying ventilation-related problems such as moisture build-up,
combustion gas build-up, etc. Record your findings on your computer
utilizing the included graphical software and cable.
Features:
- Dual beam absorption infrared
- Display: LCD
- Sample method: diffusion or flow through (50 – 100 ml/min)
- Power supply: 4 AA batteries (not included) or 6V DC from external
AC/DC adapter (included)
- Includes graphing software & computer cable
Applications:
