More info

The instrument measures the quantities: airspeed, temperature, relative humidity, atmospheric pressure, CO2 (Carbon Dioxide) and CO (Carbon Monoxide) by using P37AB147 probe.

The kit consists of: HD37AB1347 instrument, 4 rechargeable 1.2 V AA NiMH batteries, instruction manual, carrying case and Deltalog9 software downloadable here.

Note: Probes and cables must be ordered separately.

The instrument simultaneously measures the following parameters, using the P37AB147 SICRAM
probe: CO2 Carbon Dioxide, CO Carbon Monoxide, Temperature, Relative Humidity, it
calculates Dew Point, Wet Bulb Temperature, Absolute Humidity, Mixing Ratio, Enthalpy and
Atmospheric Pressure.

You can also connect Temperature and Humidity SICRAM combined probes, Hot-Wire Sensor
Wind Speed SICRAM probes, Vane Wind Speed SICRAM probes, and Temperature SICRAM
probes with Pt100 sensor, to the instrument. The instrument with memory capacity of 67,600 records for each of the two inputs. Logging interval from 15 seconds to 1 hour. The software is both powerful and sophisticated, yet user-friendly, the DeltaLog10 software enables data to be organised and analysed to provide management information.

The instrument, using a proper procedure, calculates the percentage of external air input (%
Outside Air) according to CO2 Carbon Dioxide, temperature, and Ventilation Rate.

Reference Standards:

  • Standard ASHRAE 62.1
  • Legislative Decree 81/2008.

These regulations apply to all confined spaces that could be used by people. Kitchens, baths, changing rooms and swimming pools are included, due to their high humidity. You should take into account, in regard to air quality, possible chemical, physical and biological contaminants, or the input of non sufficiently purified external air (Ventilation Rate).

The instrument has a wide Dot Matrix graphic display with a resolution of 160x160 dots.

The detected and computed quantities in the instrument are:

The instrument typical applications, using the above range of probes, are:

  • Measurement of IAQ (Indoor Air Quality) and comfort conditions in schools, offices and
  • indoor spaces.
  • Analysis and study of the Sick Building Syndrome, and of the resulting consequences.
  • Checking the HVAC (Heating, Ventilation and Air Conditioning) system efficiency.
  • Examination of IAQ conditions in factories to optimize microclimate and improve
  • productivity.
  • Building Automation checks.
