Specification
HD37AB1347 IAQ Monitor is a tool manufactured by Delta Ohm for the analysis of air
quality ( Indoor Air Quality, IAQ) .
The instrument simultaneously measures several parameters: Carbon Dioxide CO2,
Carbon monoxide CO, Temperature, Relative humidity and calculates Dew Point, wet bulb temperature, absolute humidity, mixing ratio, enthalpy and atmospheric
pressure. All this with the P37AB147 SICRAM probe. The probe SICRAM P37B147 does
not measure the Carbon Monoxide CO. Also combined temperature and humidity
SICRAM probes, Hot wire Air speed SICRAM probes, Vane air speed SICRAM probes
and temperature SICRAM probes can be connected to the instrument.
The instrument, with proper procedure, calculates the percentage of outdoor air intake
( % Outside Air) as a function of both carbon dioxide CO2 and temperature and the
Ventilation Rate.
HD37AB1347 data logger has a storage capacity of 67, 600 presets for each of the two
inputs divided into 64 blocks. Use the software DeltaLog10 version 0.1.5.0.
The instrument is equipped with a large dot matrix graphic display with a resolution of
160x160 points. Standards: ASHRAE 62.1-2004, Decree Law 81/ 2008. The rules apply
to all enclosed spaces that may be occupied by people. Should be considered, depending
on air quality, chemical contaminants, physical and biological or outdoor air flow inside inadequately purified ( Ventilation Rate) .
Typical applications of the instrument with the range of sensors mentioned above are:
- Measure IAQ and comfort conditions in schools, offices and indoor.
- Analysis and study of sick building syndrome ( Sick Building Syndrome) and
consequences.
- Verification of HVAC system.
- Investigation of IAQ conditions in factories to optimize the microclimate and improve productivity.
- Audits in Building Automation.
