USA Toll Free: 1-800-730-0302 Tel: 416-240-1920 - sales@metexcorporation.com

35 years of optical measurement expertise has allowed HF scientific to become a leader in regulatory reporting turbidimeters. The HF scientific MicroTOL Online Turbidimeter has been specifically designed to meet regulations of the EPA and ISO 7027. Features include fast and easy calibration, verification in seconds, low maintenance, fail safe design which ensures your instrument is always reading accurately, bubble rejection system, automatic continuous ultrasonic autoclean system (except MicroTOL #2 & #5 models), and a data acquisition software system that allows logging and data storage for multiple turbidimeters.

No need to monitor turbidity greater than 10NTU?

HF scientific has added four new low range models, the new 0.02-10NTU models #5 (White light and IR) and 0.02-10NTU models #6 (White light and IR) that are perfect for applications such as drinking water where a measurement range greater than 10NTU is not needed. Calibration points are 0.02, 1.0 and 10NTU.


  • Fast and easy calibration

    Verification in seconds while a complete primary calibration can be completed in less than 5 minutes

  • Low volume sample chamber
    Low volume sample chamber (30ml) reduces calibration costs and provides quick response times

  • Low maintenance fail safe design
    Simple modular design - Easy to use and service

  • Bubble rejection system
    Eliminates bubbles without delaying the response time

  • Affordable
    Modular microprocessor based technology ensures high quality at the industry's lowest price

  • Autoclean (except MicroTOL 2 and 5)
    Automatic continuous ultrasonic autoclean allows for the first EPA 180.1 accepted automatic cleaning online turbidimeter

  • Made in the USA

Optional Features

  • Online software

    Allows logging, comparisons, graphs and data acquisition for multiple online turbidimeters into a PC

  • Remote display
    Allows remote monitoring up to 500 feet away
