Sievers CheckPoint - Portable / On-Line TOC Sensors

FromSUEZ Water Technologies and Solutions

SHARE

Portable, light weight TOC sensor for microelectronics and pharmaceutical applications. The Sievers CheckPoint On-Line/Portable Total Organic Carbon (TOC) Sensor allows superior flexibility when measuring low level TOC. It can be used on-line for continuous monitoring or carried to any point in a water system. This sensor is a powerful tool for rapid diagnostic sampling and troubleshooting for microelectronics, pharmaceutical and power applications. The CheckPoint TOC Sensor is available in two models - CheckPoint Pharma and the CheckPoint^e to better serve pharmaceutical and ultrapure water applications.
