In fact, in Germany the Bernese mountain dog is referred to as Berner Sennenhund. Sennenhund literally means alpine pasture dog. Champex, Leysin, Anzere, Arosa, and Brigels are name choices derived from ski areas within the Swiss Alps.
A carbon dioxide sensor or CO2 sensor is an instrument for the measurement of carbon dioxide gas. The most common principles for CO 2 sensors are infrared gas sensors (NDIR) and chemical gas sensors.Measuring carbon dioxide is important in monitoring indoor air quality, the function of the lungs in the form of a capnograph device, and many industrial processes.he gas is pumped or diffuses into the light tube, and the electronics measures the absorption of the characteristic wavelength of light. NDIR sensors are most often used for measuring carbon dioxide. The best of these have sensitivities of 20â50 PPM.
CO detectors measure CO levels in the environment and sound an alarm to warn you to ventilate the affected area. Two basic types of CO detectors. CO detectors are either battery operated or electric. Most CO detectors on the market use one of the following three sensor types. 1. Electrolytic Sensor Detectors-This type of sensor is extremely sensitive to detecting CO in the home. Although it is the most efficient type of CO detector, it is rarely used due to its significant cost. 2.
