Testo 315-3 Ambient CO and CO2 Detector - 0632 3153

GST included.

    The high-quality testo 315-3 is an easy-to-use, ruggedly designed CO and CO2 meter that enables you to carry out quick and reliable ambient measurements according to DIN EN 50543 standard.

    Precision – from the sensor to the housing

    With a highly accurate electrochemical sensor for CO measurement and a shock-resistant infrared CO2 sensor, the measuring instrument testo 315-3 is state-of-the-art technology. It is excellently equipped to resist external influences by its robust design and the optionally available TopSafe. And that’s not all. During the measurement, optical and audible signals let you know immediately whether the variably adjustable limit values have been exceeded.

    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 andCO2 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 are 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 reading scan be transferred directly to the analyzer via Bluetooth
