CO

In order to commission heating systems safely and without

danger, you are reliant on dependable measurement

technology. For this reason, we developed our CO

measuring instruments and gas spillage detectors.

With the testo 315-4 and testo 317-3, you ensure that the

CO burden at combustion locations and frequently used

rooms is measured and monitored precisely.

testo 317-1, on the other hand, warns you quickly and

reliably of flue gas leaking from the heating system, which

is an indicator for a malfuction in the area of combustion

plants.
