Turbidity : Continuous Monitoring Industrial Online Turbidity meter

The R.M.S Continuous Monitoring Online Turbidity meter offers accurate Turbidity readings and has been specifically designed to meet regulations of the EPA and ISO 7027. Main Features of the MicroTol range include fast and easy calibration, verification in seconds, low maintenance, Turbidity readings : 0-1000 NTU's (Nephelometric Turbidity Units), bubble rejection system, optional automatic continuous ultrasonic optical cleaning system, and a data acquisition software system that allows logging and data storage for multiple turbidity meters. The fail safe design MicroTol Turbidity meter ensures your instrument is always reading accurately.

Standard Features: 

  • Calibration is simple and rapid: Verification can occur in seconds with complete primary calibration possible in less than 5 minutes. 
  • A low volume sample chamber (30ml) that due to its small size can reduce calibration costs and produce rapid response times. 
  • A fail safe design: A low maintenance modular design with simplicity at its heart, ease of servicing and use is guaranteed. 
  • Bubble Rejection System: a system that removes bubbles with no delays to the response time. 
  • Cost Effective; a technology based around modular microprocessors ensures a low price and the highest quality.

Optional Features: 

  • The first EPA Accepted Automatic Cleaning online Turbidity meter, automatically cleans ultrasonically.
  • RS-485 with Modbus:
  • High speed Modbus communications allow for digital connection.
  • Software that provides online logging, graphs, comparisons and data acquisition for anything up to 256 turbidity meters into one PC. 
  • A remote display that allow the user to monitor results anything up to 500 feet away.
