CO2 meter

ideal for biological incubators


  • Portable or data logging meter
  • In-built sampling pump with tubing/filter kit
  • AA battery powered
  • Low cost and low maintenance
  • The ESCM-10 model is ideal for biological incubators

Our CO2 meters are easy to use and maintain. Simply turn on and start taking measurements. The meter is powered via AA batteries or can be connected to mains power supply for long term measurements. The CO2 meter is delivered to you pre-calibrated and ready to go.

Our portable, battery-powered Sampling Data Logger is designed to measure carbon dioxide in enclosed environments or inaccessible areas. Use it for applications like biological incubator monitoring, CO2 fire suppression testing, modified atmosphere packaging, fermentation vats & barrels, and CO2 leak detection. The internal memory can record CO2 levels over time.

  • Lightweight, easy-grip design
  • Separate Power On/Off Switch and Logging On/Off Switch to extend battery and pump life
  • Back-lit LCD display

more details

Inside the Sampling Data Logger is a battery-operated micro-pump connected to inlet and outlet tubing ports. The unit can be programmed to automatically turn itself on (once every 15 seconds up to once every 18 hours), draw gas for a programmable period of time from the inlet port, expel it from the outlet port, and log the CO2 values with a time stamp. Later, the data can be retrieved via USB connection to a computer running our free GasLab® software

By connecting tubing to the inlet, you can remotely sample gas, or by connecting tubing to both ports, you can create a closed-loop system and return the gas back to the original container. This makes the Sampling Data Logger perfect for measuring potentially dangerous high concentrations of CO2 over hours or days.

The Sampling Data Logger comes in five models: 1%, 5%, 30%, 60% and 100% CO2. All models include a data cable for programming and retrieving logged data. It includes a back-lit LCD that changes color according to CO2 levels, filters, fittings, tubing and auxiliary international power supply.
