DO 2003 HVAC Datalogger

DO2003 is a datalogger portable instrument, specifically designed to perform measurements in air-conditioning, heating, ventilation, environmental comfort, energy saving both for industrial and residential application by means of a complete series of probes dedicated. It measures:

  • Air speed and flow rate inside pipeline with hot-wire probes, vane probes or Pitot tube probes
  • relative humidity and temperature with combined probes
  • differential pressure up to 2000 mbar and barometric pressure
  • temperature with immersion, pointed or contact probes.

This datalogger stores up to 12.000 readings which can be downloaded to a PC connected to the instrument through RS232C serial port. Storage interval, printing, baud rate can be configurated on the menu.  “Record” (RCD) function calculates maximum, average and minimum values.  A big size dual display and a led series make the reading of data easy.  The instrument is provided also with these further functions: relative measurement, Hold function, zero correction for differential pressure probes and hot-wire probes.

Display: 3½ digit, dual LCD, figure height 12,5 mm. Unit of measure and other additional information are supplied with a led series.

No. 2 inputs: input A for air speed and pressure probes, input B only for combined temperature/humidity probes.
