Detecting dangerous carbon monoxide gas to avoid CO poisoning.
The "testo 317-3/315-4" is a CO meter with an alarm that measures the concentration of carbon monoxide in the surrounding air and detects carbon monoxide from incomplete combustion, such as from burners. When it detects a concentration that exceeds the threshold, it notifies you with a screen display and alarm sound. The "testo 315-4" measures CO and atmospheric CO₂, and when connected to an optional temperature and humidity sensor, it can simultaneously measure temperature and humidity. 【Features】 ■ Notifies you with a screen display and alarm sound when the set value is exceeded ■ Alarm sound can be output to earphones (317-3) ■ Simultaneous measurement of temperature and humidity is possible when connected to a temperature and humidity sensor (optional) (315-4) *For more details, please download the PDF or feel free to contact us.
