The HD31 is a portable multifunctional instrument and datalogger with a large (43 x 58 mm) colour graphic LCD display.
It has three independent inputs. Both single and combined SICRAM probes can be connected to each input to measure a variety of physical quantities:
- Temperature
- Relative humidity
- Atmospheric and differential pressure
- Air speed
- Illuminance (lux) and Irradiance
- Carbon dioxide (CO2) – Air Quality
- Direct voltage (VP473 module) and current (IP472 module)
Sampling speed one per second each channel. Storage capacity 32,000 samples per channel.
Functions: CLOCK, HOLD, RELATIVE, DIFFERENCE, MINIMUM, MAXIMUM, AVERAGE. Simultaneous display of three measurements. Calibration of the individual probes with permanent storage of the calibration data inside the probe: probes can be changed without losing the calibration.
The instrument allows the input of various types of probe of different physical quantities. Platinum probes (25, 100, 500 Ω at 0 °C), Thermocouples K, J, E, T, N, R, S, B probes, combined R.H. and temperature, pressure also barometric one, air velocity, light, CO2 , mV and mA probes can be connected.
Centesimal temperature measurements can be carried out by PRT sensors in the range –200…+350°C, and decimal in the range +350…+850 °C.
Supplied with: rechargeable lithium ion battery, SD card, rubber protection shell with magnet, USB cable CP31, power supply SWD05, Deltalog9 software downloadable here, instruction manual and carrying case.
The modules, probes and serial cable for the printer must be ordered separately.
