On-Line TOC Sensor is Portable, Battery-Operated

The new CheckPoint Portable/On-Line Total Organic Carbon (TOC) Sensor from GE Analytical Instruments allows measurement of low level total organic carbon (TOC) anywhere, anytime. It is the first and only battery-powered TOC measuring device according to the company. It can be hand-carried to any point in a water system for rapid diagnostic sampling and troubleshooting or used on-line for continuous monitoring for microelectronics, pharmaceutical and power applications.

The CheckPoint TOC Sensor has a range of 0.05 to 1,000 ppb, and can measure TOC in water with up to 1.4 µS/cm conductivity from CO2. CheckPoint also measures conductivity/resistivity and temperature. CheckPoint features an Ethernet (Modbus over TCP/IP) and a USB port for convenient data download. CheckPoint requires no reagents, and is easy to operate and maintain. Calibration is typically stable for six months.
