Water Turbidity Meter MicroTol

Benefits

  • Quick and easy calibration.
  • Verification in seconds, a complete primary calibration in less than 5 minutes.
  • Low volume sample chamber (30 ml) reduces calibration costs and provides fast turnaround times.
  • Low maintenance and safe design.
  • Simple and easy to use modular design.
  • Bubble rejection system.
  • Eliminates bubbles without delaying response time.
  • Modular microprocessor-based technology, which guarantees a high quality of information.
  • Self-cleaning (except MicroTOL 2 and 5).
  • Automatic and continuous ultrasonic self-cleaning under EPA 180.1 standards for meters and turbidimeter self-cleaning.
