Exciting Update!

Multi Gas Sampling Data Logger

CO2Meter is delighted to announce that we have sunset the previous lineup of Sampling Data Loggers. We have upgraded our data logger lineup with the NEW  CM-1000 GasLab® Pro Multi-Gas Sampling Data Logger. The new CM-1000 lineup now includes 60 custom sensor configurations, data logging to a micro SD card, a large LCD display, and Li-Ion rechargeable batteries.

Please visit the CM-1000 product page to purchase this improved model. 

The CO2Meter Team

Our portable, battery-powered 100% CO2 Sampling Data Logger is designed to measure carbon dioxide in enclosed environments or inaccessible areas. Use it for applications like biological incubator monitoring, modified atmosphere packaging, fermentation vats & barrels, and as a CO2 sniffer for 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
  • Programmable CO2 level alarm
  • 60,000 data points in memory
  • Built-in 1,000-hour micro pump (upgrade to 10,000 hours on request)
  • Impact-resistant case, power supply, tubing/filter kit, and USB cable

Inside the Sampling Data Logger is a battery-operated micro-pump connected to inlet and outlet tubing ports. The unit can be programmed to measure at specific intervals, 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.

Are you doing Fire Suppression Testing?  Do you have to meet NFPA 12 & 17 requirements for CO2 concentration testing?  If so, complete the required, simultaneous three level testing with our 3 Pack of 100% Sampling Data Loggers.  We offer a 10% discount for purchasing 3 devices.
