Thanks to the large display, the values are particularly easy to read. Monitoring room temperature is an important factor for a comfortable and healthy living environment and helps save energy. Even a one-degree reduction in temperature can lead to up to 6% lower heating costs. When placed by the window, the sensor cable for measuring the outside temperature can be easily routed outside. The max-min memory with manual reset allows for monitoring peak values over a self-selected period. The applications of thermometers with sensor cables are diverse and not limited to outside temperature. The waterproof measuring probe can also be used for temperature control in refrigerators and freezers due to its wide measuring range, or for measuring water temperature in aquariums.
