Logging baro-thermo-hygrometer D4130

Comet System
  • Included traceable calibration certificate
  • Dual line LCD display with special symbols
  • Dew-point reading
  • Barometric pressure tendency reading for last three hours
  • Memory of minimum and maximum values

Description

Thermometer, hygrometer, barometer is designed for measurement and datalogging of temperature, relative humidity and atmospheric pressure into the internal non-volatile memory. Also barometric pressure tendency reading available. Free PC program enables to transfer recorded data via RS232 serial link to the computer for evaluation. 

Data logger is connected to the PC through included communication cable only for data trasfer from the memory. During connection with the PC no measurement and record is enabled.

Simultaneous reading of temperature and air relative humidity, dew point temperature and air pressure reading selectable, built-in sensors, barometric pressure tendency reading for last 3 hours.
