temperature data-logger / humidity / programmable / RS-232C

The HD37AB17D and HD37B17D data loggers are designed to simultaneously measure and store relative humidity (RH), room temperature (T), carbon monoxide (CO) (only HD37AB17D) and carbon dioxide CO2, providing detection and control of the indoor air quality. Commonly they are used in schools, hospitals, auditoriums and cafeterias (buildings with crowds of people), as well as workplaces in order to improve comfort and detect CO2 leaks and potential fire and explosion hazards. These units allow quality air conditioning, by adjusting temperature and humidity, and ventilation control via air change per hour, according to ASHRAE standards, while also reducing energy consumption according to current BMI and energy savings.
