Description

Mini hygro thermometer PCE-444 Mini hygro thermometer as pocket device for air humidity and temperature / simple handling / one-handed operation / for orienting measurement / HOLD function Determination of dew point and wet bulb temperature / Extreme value measurement The mini hygro thermometer is a measuring instrument for the prompt measurement of temperature and air humidity. This mini hygro thermometer is used for orienting measurements in rooms. For these orienting measurements, the mini hygrometer thermometer only needs to be switched on. A measurement of temperature and relative ambient humidity starts immediately after switching on. Because the mini thermo-hygrometer is operated with batteries, it is best suitable for measurements without any connection to the location. The built-in buttons also enable one-handed operation. The mini hygrometer thermometer has an automatic switch-off function that switches the device off after 15 minutes of inactivity. If this is deactivated, it is possible to carry out long-term measurements with the measuring instrument. The extreme value functions (MIN / MAX) support this. Over the entire period of time, measured values are monitored and the respective highest or lowest values are shown on the display. Precise sensors were installed in the mini hygro thermometer, which permit fast orienting measurements. In addition to the corresponding measured values, other information is also passed on to the user on the display.
