Battery-Powered TOC Sensor Allows Sampling Anywhere, Anytime

GE Analytical Instruments, a division of GE Water & Process Technologies, announces its new CheckPoint Total Organic Carbon (TOC) Portable/On-Line Sensor, the first and only battery-powered TOC measuring device. CheckPoint can easily be hand-carried to any point in a water system for rapid diagnostic sampling and troubleshooting, or used on-line for continuous monitoring.

CheckPoint’s portability, fast analysis time, and versatility enable new problem-solving and diagnostic capabilities at points of use away from power sources. The Sensor typically operates four to five hours using the optional battery, or continuously with AC power. It weighs just 3.6 kg (7.9 lb.), and features a 15-second default measurement, adjustable in intervals up to eight hours.

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 uS/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.
