Abstract

A handheld engineering surveying thermometer belongs to the technical field of engineering surveying equipment, and specifically relates to a handheld thermometer. The handheld engineering surveying thermometer comprises a host machine which is equipped with an LED. A positioning laser switch, a temperature conversion switch and a backlight lamp switch are arranged below the LED. The front end of the host machine is provided with a detection hole. A laser emission hole is arranged above the detection hole. A detection switch is arranged on the host machine, and a laser is arranged in the host machine. According to the invention, the thermometer is started by pulling the detection switch, positioning is carried out through the detection hole, the temperature is displayed on the LED after the detection switch is pulled, the temperature remains on the LED after the detection switch is released, and the thermometer is very convenient to operate.

Description

technical field [0001] The invention belongs to the technical field of engineering measurement equipment, and in particular relates to a hand-held engineering measurement thermometer. Background technique [0002] With the continuous development of the economy, the investment of a large number of advanced power equipment and power facilities continues to increase, and the power load has risen sharply. Use temperature measurement technology to increase the daily inspection of power equipment and power facilities to ensure the safe operation of power equipment and facilities. play a hugely important role. Since the damage of electric equipment and electric facilities due to local heating faults is increasing year by year, causing direct economic losses to electric power enterprises and users, it is very important to strengthen the temperature measurement of electric equipment and electric facilities. Due to the exposed high voltage and the narrow space in the high-voltage pow...
