Oxygen Pen hardner this species is considered invasiveThis 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
