MTL-30 Temperature Humidity Logger
The MTL-30 is a self-contained, precision instrument for recording the temperature and relative humidity of the
surrounding environment. The MTL-30 can store up to 43,344 temperature samples, or up to 21,672 of both
temperature and relative humidity samples. In addition to Temperature and Humidity, the DwyerLog software
computes and displays the Dew Point Temperature.
The MTL-30 logger temperature and relative 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, causing damage to the internal electronics.
Warning: Care must be taken to ensure that the logger is not operating under condensing conditions. This
means that the dew point temperature must be below the ambient temperature. Condensation will damage the
humidity sensor and the logger electronics.
MTL-30 Logger Status LED
Pressing the Start/Check button makes the LED flash a series of flashes to indicate the logger status. The table
below shows the different logger states that the status light can show.
