Protmex CECOMINOD046940 is a digital temperature and humidity meter that can display three types of temperatures around the sensor's air: the ambient temperature, the dew-point temperature, and the wet bulb temperature. It has a large display screen that shows the measurements in clear, easy-to-read digits. The meter also has a number of features that make it easy to use, including a hold function, a max/min function, and a data logging function.

The hold function freezes the current reading on the display, so you can take your time to record the data. The max/min function shows you the highest and lowest readings that have been recorded, so you can track changes in temperature and humidity over time. The data logging function allows you to store up to 99 readings in the meter's memory, so you can easily transfer them to a computer for further analysis.
