The GasLab Pro Multi Gas Sampling Data Logger (CM-1000) is designed to simultaneously measure multiple gas concentrations through a sampling method. As a unique, multi gas sampling unit, the GasLab Pro is a convenient device to monitor multiple gases in a single unit.

Utilizing a micro pump, the device will draw samples in to the sensing chambers allowing each sensor to take a fast and accurate measurement of the sample.

The GasLab Pro also features safety alarms (80 dB), maximum and minimum readings, Time Weighted Average (TWA, 8 hour exposure, CO2 only), and Short‐Term Exposure Limit (STEL, 15 min. weighted average for CO2 only).

The GasLab Pro measures up to two gases including:

  • Carbon Dioxide
  • Carbon Monoxide
  • Oxygen
  • Temperature
  • Relative Humidity
  • Barometric Pressure


  • Handheld Multi Gas Detector
  • Manual
  • USB 1.5M cable
  • Tubing
  • Hydrophobic and Particulate Filters
  • Water Trap
