This pen style meter reads oxygen (O2) level and air temperature, and is easily portable and designed for simple one-hand operation. 

Reads oxygen in air for environmental studies, IAQ, bio-technology (for oxygen incubators and anaerobic cultivators), food storage and refrigeration, and testing fire alarm and fuel cell systems.

The fast, highly reliable, galvanic oxygen sensor is unaffected by acidic gases such as CO2. Simultaneously displays O2 concentration and air temperature in °C or °F. Features hold, min/max, a low battery indicator, ATC and auto-power-off. Comes with 4 AAA batteries and a soft carrying case with a belt loop and shoulder strap.

Dimensions: 7" × 1½" × 1½" (178 × 38 × 38 mm)
