Air Quality Meter HD 37AB1347

indoor air quality meter to measure various parameters (CO2, CO, temperature, relative humidity) / calculates dew point, wet bulb temperature, absolute humidity, specific humidity, enthalpy, and atmospheric pressure)

The indoor air quality meter is a type of instrumentation that allows you to analyze and check air quality (INDOOR AIR QUALITY, IAQ). With the indoor air quality meter, you can measure various parameters CO2, CO, temperature, relative humidity, and it can also calculate the dew point, wet bulb temperature, absolute humidity, specific humidity, enthalpy, and atmospheric pressure using the P37AB147 probe. The only thing you cannot measure with this probe is carbon monoxide. This indoor air quality meter can also connect combined probes for measuring temperature and humidity, hot wire air velocity probes, fan air velocity probes, and other temperature probes. With the indoor air quality meter, you can calculate the percentage of outside air injection (% Outside Air) based on carbon dioxide, temperature, and renewal frequency. The indoor air quality meter has internal memory to store 67,600 values for each of the two inputs divided into 64 blocks. This indoor air quality tester has a graphical dot matrix display with a resolution of 160x160 dots according to the standard reference ASHRAE 62.1-2004, Italian Law Decree 81/2008 indicating that it applies to all enclosed spaces that can be occupied by people. Due to the presence of high humidity, kitchens, bathrooms, changing rooms, and swimming pools are also included. Any type of chemical, physical, and biological contaminant or outside air that is brought inside and not adequately purified must be taken into account according to air quality.
