CO2 sampling data logger

– ideal for biological incubators & research projects

Portable O2 DetectorChoice of measurement range:
  • ESCM-01 0 to 1%
  • ESCM-56 0 to 5%
  • ESCM-02 0 to 30%
  • ESCM-50 0 to 60%
  • ESCM-03 0 to 100%

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.

CO2 Detector and PumpInside 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.
