The LTH is a self-contained, precision instrument for recording the temperature and humidity of the surrounding environment. The LTH can store up to 21,500 temperature samples, or up to 10,750 of temperature and humidity samples. In addition to Temperature and Humidity, the LOGiTpc software computes and displays the Dew Point and the Wet Bulb Temperatures.
By default, the LOGiTpc software will only show the Temperature, Humidity and Dew Point data. To view the Wet Bulb Temperature data, from the View menu, select Channels >, and click on Wet Bulb. You can find more information in the Hiding and Viewing Channels section.
The LTH logger temperature and humidity sensors are open to the air. It is therefore important to ensure that water does not get into the unit. This is especially important in high humidity situations (90% RH and above) where water may condense inside the logger, damaging the logger.
Caution!!!
Care must be taken to ensure that the logger is not operating in condensing conditions. This means that the dew point temperature must be below the ambient temperature. Condensation may damage the humidity sensor and the logger electronics.
