A particularly useful and handy instrument for measuring humidity, CO2, CO, atmospheric pressure and temperature in spaces. It is equipped with a data logger, so that all information afterwards can be easily used in reports.

The instruments simultaneously measure the parameters:

Carbon Dioxide CO2
Carbon Monoxide CO
Atmospheric Pressure
Temperature
Relative Humidity

The instrument calculates:

Dew Point
Wet Bulb Temperature
Absolute Humidity
Mixing Ratio
Enthalpy

The HD21AB is a datalogger with a memory capacity of 67600 recordings, divided in 64 blocks. It uses the DeltaLog10 software from version 0.1.5.3. Reference Standards: ASHRAE 62.1 - 2004, 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 the presence of high humidity. You should take into account, in regard to air quality, possible chemical, physical and biological contaminants.

The instruments have a wide Dot Matrix graphic display with a resolution of 160x160 dots. The instruments typical applications 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.
