Air quality meter PCE Instruments

Product description:

• Indoor air quality meter and measurement converter.
• It is a product with automatic calibration.
• The meter is used to determine
  • CO2 content of the air.
  • Temperature.
  • Relative humidity.
• The product is used to assess the ambient climate in hotels, offices, shops, etc.
• It has an optical NDIR sensor, which is responsible for measuring the CO2 in the environment.
• The product measures 12.6 cm wide x 9 cm high x 5 cm deep.
• The housing material is plastic.
