Product Specification

O2-G1 Oxygen Sensor (O2 Sensor) Description
Alphasense Oxygen sensors use capillary flow control.
Unlike partial pressure oxygen sensors, they have good pressure and temperature dependence, making them the best choice in safety applications.

Standard galavanic sensors use lead for greatest reliability but fixed lifetime.

O2-G1 Oxygen Sensor size:
Miniature, proven long-term performance. The sensors are designed for the next generation of portable gas detectors. Part of the Alphasense ‘D‘ family.

O2-G1 Oxygen Sensor Key Features & Benefits:
Small Footprint
Reduced Height
Low Weight
Good Connectivity: Uses industry standard, low cost, Molex sockets for direct board insertion.
Reduced Costs: High quality design with a significant reduction in the cost per measured gas, allied to reduced manufacturing costs are passed on to OEMs
