testo 315-4 Ambient CO measuring instrument 

State-of-the-art technology, easy to use, robust design: the testo 315-4 CO measuring instrument is your reliable partner for measuring carbon monoxide in the ambient air. You can, for example, detect CO in the ambient air around heating systems. There is also the option to measure humidity and temperature in parallel.

You can view the measurement results directly on the digital display. If the individually adjustable limit values are exceeded, the CO measuring instrument emits an optical and acoustic alarm.

The cleverly designed CO measuring instrument with lithium polymer battery ensures energy-saving operation: when not in use, it switches off automatically.
