Thermal microclimate refers to environmental parameters that affect heat exchange between the human body and the environment within a limited location or space, indicating what is known as "thermal satisfaction." The micro (local) environment in a specific working environment influences a series of biological responses related to a person's state of satisfaction (comfort) or thermal anxiety (discomfort). In fact, the human body strives to maintain thermal balance in order to keep body temperature at an optimal level. ▲ High-precision measurement of WBGT index (indoor/outdoor), PMV/PPD values, TU, and DR index ▲ Long-term data logging with large-capacity memory and built-in lithium-ion battery ▲ Large color graphic LCD touch panel with high visibility and operability ▲ Compliance with ISO7730, ISO7726, ISO7243, and ASHRAE55 standards

This is a portable measuring device and data logger designed for the analysis of indoor air quality (IAQ). It measures multiple parameters including carbon dioxide (CO2), carbon monoxide (CO), temperature, relative humidity, and atmospheric pressure with a single unit. Additionally, it can calculate and display dew point temperature, wet bulb temperature, absolute humidity, mixing ratio, and enthalpy. Measurement of these parameters is possible by connecting the SICRAM module with probe P37AB147 to the main unit. Besides probe P37AB147, temperature and humidity combined probes with SICRAM modules, hot-wire and vane-type air velocity probes, and temperature probes can also be connected. The main measuring unit calculates the percentage of outdoor air intake (% outdoor air) based on CO2, temperature, and ventilation rate. ▲ Simultaneous measurement and data logging of CO2, CO, humidity, temperature, and atmospheric pressure ▲ 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) ▲ Air quality monitor based on ASHRAE 62.1–2004 standards
