D3121 Portable handheld temperature and humidity meter with COMET external sensor

Description

D3121 A portable handheld thermometer and hygrometer with an external sensor (known as a probe) designed to measure and record temperature and relative humidity in internal memory.

The free PC software allows you to download the recorded data to a computer where it can be evaluated. The device has an LCD backlight.

The data logger is connected to a computer. Connection to a computer does not allow measurement or recording. It comes with a USB cable for transferring data from the memory.

The device provides simultaneous temperature and relative humidity readings, optional dew point temperature readout, outdoor temperature and humidity probe with 1 m cable. Cable lengths of 2 and 4 metres are available on request. The probe has a diameter of 18 mm and a length of 135 mm.
