5、 Humidity and temperature measurement

sensorThe temperature and humidity semiconductor sensor is located inside.

liquid crystalmonitor4-1/2 bit dual LCD display, capable of displaying units such as ℃, ℉,% RH, dew point, wet bulb, and low-power "images" MIN/MAX、HOLD。

Large/small value measurement button:

Press the size measurement button to enter the size measurement mode. Before selecting the size value function, choose a suitable range to ensure that the size reading does not exceed the testing range. Press this key once to select the high value, and press it again to select the low value. Press and hold this button for at least 2 seconds to turn off the size measurement function and enter normal mode. Select the ℉, ℃, Dew Point, and Wbt buttons to enter the ℉, ℃, Dew Point, and Wbt measurement modes.

Power switch button:

OninstrumentPress to open the instrument panel, then press to close the instrument panel.

HOLD/Backlight button:

Press the HOLD/Backlight button to enter the data hold function, and the current reading will be held. Pressing it again will cancel the hold function and enter normal mode. When pressed for more than 2 seconds, the backlight will turn on, and when pressed for more than 2 seconds, the backlight will turn off. When the battery level is low, open the battery box and replace the battery.

Note:

① Do not immerse sensors or instruments in liquids; This sensor is used in the air

② Exposure to working conditions or chemical vapors may affect instrument accuracy and damage the instrument

③ When measuring the humidity of chemical vapor with this instrument, the diffusion of chemicals in the sensor causes a decrease in the accuracy and sensitivity of the instrument, which can be slowly restored by placing the instrument in a pure environment for a long time.
