Portable measuring device and data logger designed for the analysis of indoor air quality (IAQ).
This is a portable measuring device and data logger designed for the analysis of indoor air quality (IAQ). It simultaneously measures the following elements: ● Carbon dioxide ● Carbon monoxide ● Atmospheric pressure ● Temperature ● Relative humidity Additionally, it calculates and displays the following elements: ● Dew point temperature ● Wet bulb temperature ● Absolute humidity ● Mixing ratio ● Enthalpy The HD21ABE17 also features a data logger function with a memory capacity of 67,600 data points divided into 64 blocks. The reference standards are ASHRAE 62.1-2004 and Legislative Decree 81/2008. The HD21ABE17 is equipped with a "1-minute average value" function that calculates and holds the average of the measurements over one minute on the display, making it applicable to all enclosed spaces used by people. It is equipped with a large dot matrix graphic display with a resolution of 160×160 dots. ▼ Simultaneous measurement of CO2, CO, atmospheric pressure, temperature, and humidity, with data logging ▼ Utilizes dual-wavelength NDIR sensors (for CO2) and electrochemical sensors (for CO) ▼ Logs 67,600 data points at variable intervals (15 seconds to 1 hour) ▼ Function for calculating and holding the 1-minute average of measurements
