Hygro-Thermometer Anemometer/Data Logger Microprocessor Controlled Model with Interface

Model HTA4200

  • Very high accuracy
  • Display of air velocity in fpm or mps
  • Display of temperature on °F or °C
  • Memory circuit for maximum, minimum and average
  • Display of calculated dewpoint in °F or °C
  • Data acquisition for up to 1000 triple measurements
  • Serial output through standard RS232C data-link
  • Automatic display and battery test
  • User-friendly keypad for simple operation
  • 3 Separate analog outputs
  • Optional timing unit available for automatic data saving
  • RS232 Interface

This portable combination instrument is ideal for measuring relative humidity, temperature and air velocity in the air conditioning, heating and ventilation fields. With the built-in memory up to 1000 triple measurements (%RH,°F/°C, and fpm/mps) can be stored; the collected data can be transferred to the optional Model IMP-2600 printer (uses standard 2" calculator paper) or a PC through the standard RS232C interface. Optional display software for IBM compatible computers available. Price includes humidity/temperature probe, airflow/temperature probe, 3 extension rods, 1 flexible rod, 1 extension cable, 1 RS232 adaptor cable, 1 analog output cable, rugged carrying case and manual.
