The Autool TM101 is a digital thermo-hygrometer, designed to measure both temperature and relative humidity in various environments. The meter has a temperature measurement range from -20°C to 60°C and a humidity range from 0 to 100% RH. The measurements are displayed on a 1.6 inch LCD display with backlighting, enabling reading in dark conditions.
In addition to the standard measurements, the TM101 has the ability to calculate and display the dew point temperature and the wet-bulb temperature. The data hold function allows the user to freeze the current measurement on the screen for later notation. With the MAX/MIN mode, the highest and lowest measured values can be stored and viewed. The meter automatically switches off after five minutes of inactivity to extend battery life.
Application and functionality:
The TM101 offers multiple measurement functions for detailed environmental analysis.
- Temperature and humidity measurement: Measures the ambient temperature and relative humidity.
- Dew point temperature (Td): Calculates the temperature at which water vapor in the air condenses into liquid water.
- Wet-bulb temperature (Wb): Measures the temperature as indicated by a thermometer with a water-moistened sensor, reflecting the effect of evaporation.
- Data Hold function: Locks the current measurement on the display for easy reading.
- MAX/MIN mode: Records and displays the maximum and minimum measured values since the start of measurement.
- Selectable units: Allows switching between temperature units Celsius (°C) and Fahrenheit (°F).
- Backlit display: Activates the screen's backlight for use in low-light environments.
- Automatic shut-off: Automatically turns off the device after 5 minutes of inactivity to save energy.
