HTF300Ex weighing terminal

The HTF300Ex is an industrial terminal which is suitable for calibration in a stainless steel housing, can be used in Ex zones 1, 2, 21 and 22. This terminal is ideally suited for difficult ambient conditions and strict hygienic requirements.

Typical applications for the HTF300Ex include its use as a mobile weighing station, as a simple weighing terminal or as filling scales.

The advantages of the HTF300Ex are:

  • Extensive standard software
  • Can be calibrated
  • For universal use
  • Easy to use via industrial membrane keypad
  • Comprehensive connection options
  • Can be used for mobile & stationary applications
  • Internal 230 VAC power supply
