0-25% O2 Sampling Data Logger

0-25% O2 Sampling Data Logger

Inquiry Catalog


CM-0505 25%

The Portable O2 Sampling Data Logger lets you log Oxygen levels over time in inaccessible areas and closed samples via the built-in gas sample draw pump. Use it for:

Fermentation monitoring & validation
Biological incubators
Agricultural O2 up take analysis
Modified Atmosphere Packaging (MAP)
Grain storage mold potential monitoring
O2 leak detection
Fire suppression system testing

Inside the Sampling Data Logger is a battery-operated micro-pump connected to two 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 DAS 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 controlled or modified atmosphere packaging (MAP), or measuring potentially dangerous Low concentrations of O2 in biological applications over hours, or even days.

The battery-operated, portable Sampling Data Logger only comes in a 0-25% O2 model. Model includes a data cable for programming and retrieving logged data, a back-lit LCD that changes color according to O2 levels, filters, fittings, tubing, and auxiliary international power supply.
