The new CheckPoint Portable/On-Line Total Organic Carbon (TOC) Sensor from GE Analytical Instruments allows you to measure low level total organic carbon (TOC) anywhere, anytime. The first and only battery-powered TOC measuring device, the CheckPoint TOC Sensor has redefined portability and flexibility. 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 dynamic range of 0.05 to 1,000 ppb, and can measure TOC in water with up to 1.4 ÁS/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.

CheckPoint won Instrument Business Outlook's (IBO) 2008 Gold Award for portable instrument design.
