Electronic thermometer with wireless temperature sensor, low high temperature alert

A wireless electronic thermometer with a remote sensor can be used to monitor the temperature in an apartment, in a house, for large refrigerators, seedling greenhouses, incubators, and other places where temperature control is needed. This thermometer is interesting because to install the sensor in another room you do not need to run a wire or drill holes; the wireless sensor even works through walls. The screen of the thermometer itself is large, and most importantly, there is an alarm function: if the specified lower or upper temperature threshold is exceeded, the main unit will then emit a sound signal. Peculiarities: - The screen of the digital thermometer displays the current temperature from the sensor installed in the thermometer body (i.e., room temperature), readings from wireless sensors (outside temperature), as well as the minimum and maximum temperature values for the history of measurements. - The thermometer can notify with a sound alarm; if the temperature limits set by the user are exceeded, for example, the temperature in the greenhouse drops below the set limit, the thermometer in the room will emit a long sound signal. - The thermometer body has a stand for installation on a table, a wall mount, and an additional magnetic mount. The sensor has a wall mount and a hook. Characteristics: - Maximum operating distance of wireless sensors: up to 100 meters (without obstacles, if there are obstacles, the working distance will decrease) - Indoor temperature measurement range: 0℃~50℃ - Outdoor temperature range from wireless sensors: -40℃~60℃ - Food: 2 pcs. AAA batteries for the main unit and 1 AA battery for the sensor (batteries not included). - Dimensions of the main unit with screen: 96 x 84 x 20 mm - Size of wireless temperature sensor (excluding mount): 104 x 35 x 18 mm Equipment: 1 x Thermometer unit with screen (battery not included) 1 x Wireless temperature sensor 1 x User Manual
