TM7755 Handheld Indoor CO2 Air Quality Meter with NDIR

The TM7755 Handheld Indoor CO2 Air Quality Meter is an easy-to-use and a comfortable-to-carry instrument ideal for Indoor Air Quality (IAQ) diagnosis. Updating readings every second, the TM7755 measures CO2 level, Air Temperature, Dew Point (DP), Wet Bulb Temperature (WB) and Humidity (RH). Featuring an audible alarm for when CO2 concentrations exceed the limit, this meter uses Non-Dispersive Infrared (NDIR) technology to ensure reliability and long term stability. This makes it exceedingly useful for verifying HVAC system performance and air ventilation controls.

The TM7755 CO2 meter is CE marked and with its NDIR (non-disperse infrared) sensor it complies fully to the guidelines as set out by the HSE (Health & Safety Executive) for CO2 monitors recommended to reduce the risk of COVID-19 aerosol transmission in poorly ventilated areas.

Measuring Ranges

  • CO2: 0 to 9999ppm
  • Temperature: -10 to 60°C
  • Humidity: 0.1% to 99.9% RH
  • Dew Point: -20.0 to 59.9°C
  • Wet Bulb: -5.0 to 59.9°C

The portable design of the CO2 Air Quality Meter is supported by a digital triple display, presenting the collected CO2, temperature & humidity readings both quickly and simultaneously. With manageable calibration and a built-in port for PC connection, the TM7755 also includes a wealth of useful features. A backlight is incorporated for working in dark areas, auto-off operation turns off automatically after 20 minutes of inactivity and hold data, Min/Max functions are useful for manipulating on-screen data.
