PEMENOL 12V Red Fahrenheit Digital Temperature Meter -76F~999F LED Display with Industrial Grade 0.5m K-Type Thermocouple Temperature Sensor M6

High Temperature Measurement: The K-type thermocouple thermometer is capable of measuring temperatures ranging from -76°F to 999°F. For temperature measurements within the range of -9.9°F to 99.9°F, the minimum temperature measurement increment is 0.1°F, while for other temperature ranges, the increment is 1°F. The thermometer requires a DC power supply voltage of 4V to 28V.
LED Digital Display: Equipped with a LED digital display, this device boasts a larger and brighter font, which makes it effortless to observe the temperature status. Whether in dimly lit or bright environments, the display is easily visible, providing accurate readings at a glance.
Industrial Grade K-type Thermocouple M6 Probe: The thermometer utilizes a K-type thermocouple sensor that incorporates a cold junction compensation function, effectively minimizing the influence of ambient temperature on the sensor and resulting in highly accurate temperature measurements. However, due to the wide temperature measurement range, some measurement errors may occur, which is considered normal within a range of ±10℉/1%.
NOTE: We highly recommend wrapping the probe with insulating tape to prevent static interference. If possible, it is better to use an insulated probe to ensure accurate temperature readings. Taking these precautions will help maintain the reliability and precision of the thermometer.
Application: This thermometer finds wide application in industrial temperature measurement. It can be used for measuring temperature in boilers, air, liquids, and various other mediums. Its versatility and accuracy make it an essential tool for industrial and personal use alike.
