Instruments are designed for direct measurement and datalogging of temperature, relative humidity and atmospheric pressure into the internal non-volatile memory. Free PC program enables to transfer recorded data via RS232 serial link to the personal computer for consequent evaluation. Instrument 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.
Advantages:
- included calibration certificate from the manufacturer
- dual line LCD display with special symbols
- adjustable dual alarm with audio indication for each channel
- memory of minimum and maximum values
- function Hold - manual storing of actual values for later displaying
