    1 INTRODUCTION HD31 is a portable multifunction and data logger instrument. It has a large (43 x 58 mm) color graphic LCD display. It is equipped with 3 independent inputs. Each input can be connected to individual and com- bined SICRAM probes (intelligent and interchangeable probes capable to store calibration data into memory) for the measurement of several physical qualities: •...
