    Cutting-edge technology, easy to use, rugged design. These are just a few of the features which make the testo 315-3 stand out head and shoulders above the rest. The CO and CO2 meter is designed to measure carbon monoxide and carbon dioxide parallel in heating systems and ventilation ducts. The readings are presented on an easy to read display. A visual and audible alarm is activated when CO/CO2 thresholds are breached. The thresholds can be adjusted to suit your range of applications.

    The intelligently designed meter has an energy-saving lithium polymer rechargeable battery and powers off automatically when not in use.

    And here’s yet another practical feature: the CO and CO2 meter for ambient measurements can also be used in combination with the testo 330-2 flue gas analyzer. The CO/CO2 readings can be transferred directly to the analyzer via Bluetooth.
