On-line TOC, BORON Analyzers
The 500 RL TOC Analyzer combines an innovative design with the proven and trusted Sievers membrane TOC technology to ensure maximum uptime and reliability. While most on-line TOC technologies are limited to only ultra-low conductivity water, the 500 RL’s unique technology allows it to meaure TOC in water up to 25 uS/cm.

The 500 RL Analyzer is not only the most robust and easy to implement TOC analyzer available, but is also a fully compliant on-line conductivity instrument. Raw conductivity and temperature data are available to support global regulatory requirements. The instrument even includes built-in USP/EP/JP conductivity “look-up” charts for Stage 1 testing. The 500 RL constantly verifies compliance and can immediately notify an operator via alarm or Modbus TCP/IP outputs.
For several decades, the Sievers brand of TOC analyzers have been reliable and extremely easy to use. The 500 RL Analyzer is very user-friendly due to its automated calibration and suitability protocols. In addition, the 500 RL has a color touch-screen display that makes it easy to configure instrument parameters and view data in tabular or graphical form. The interface also provides real-time status of consumables, with prompts when semi-annual maintenance is due.
The patented Sievers One-port Integrated On-line Sampling System (iOS System) and innovative four-port Super iOS System fully automates all system protocols and can also analyze a quick grab sample for trouble shooting a specific port on your water system.
