Hygro-Thermometer Anemometer/Data Logger
Model HTA 4200

  
Model HTA 4200 is a portable combination instrument for measuring relative humidity, temperature and air velocity in the air conditioning, cooling, heating and ventilation industry. With the built-in memory up to 1000 triple measurements (%RH, °F/°C, and FPM/MPS) can be stored and the collecter data can be transferred to a printer or PC through a RS 232 C Interface.
