Checkpoint TOC Sensor

cp_new_270.jpgThe Checkpoint Portable TOC Analyzer - weighing just 3.6 kg (7.9 lb), the battery-operated CheckPoint TOC Sensor can be used anywhere for continuous on-line monitoring, rapid on-line monitoring, or grab sampling.

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 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.

CheckPoint Portable/Online TOC Sensor won Instrument Business Outlook's (IBO) 2008 Gold Award for portable instrument design.
