CheckPoint On-Line/Portable Total Organic Carbon (TOC) Sensors

REQUEST QUOTATION

The affordable CheckPoint On-Line/Portable Total Organic Carbon (TOC) Sensors from GE Analytical Instruments allows you unsurpassed flexibility in measuring low level total organic carbon (TOC). It can be used on-line for continuous monitoring or hand-carried to any point in a water system for rapid diagnostic sampling and troubleshooting for microelectronics, pharmaceutical and power applications. The first and only battery-powered TOC measuring device, the CheckPoint TOC Sensor has also redefined portability.

The CheckPoint TOC Sensor is available in two models - the CheckPoint Pharma and the CheckPointe.

CheckPoint Pharma

The new, economical CheckPoint Pharma TOC Sensor is designed for pharmaceutical applications. The CheckPoint Pharma has a dynamic range of 0.21 to 1,000 ppb, can measure TOC in hot (up to 90 C) or ozonated water, and will operate at ambient temperatures up to 55. CheckPoint Pharma provides three analog outputs for simultaneous TOC, raw conductivity and temperature measurements to support regulatory requirements, and new USB printer support provides an affordable way to meet 21CFR Part 11 compliance. All backup sensor data is stored in memory and users can define a date range for faster data downloads. Standard operating procedures are provided for IQ (Installation Qualification), OQ (Operation Qualification), and PQ (Performance Qualification) to simplify sensor validation. Its Standard Operating Procedure (SOP) meets minimum United States Pharmacopeia (USP), European Pharmacopeia (EP), Chinese Pharmacopeia (CP), and Indian Pharmacopeia (IP) requirements.

CheckPointe

The CheckPointe, for microelectronics (semiconductor), power, and other applications, provides a wider 0.04 to 1,000 ppb operating range for more sensitive environments where hot and ozonated samples are uncommon.

CheckPoint Pharma and CheckPointe Common Features

Both models feature 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.

The versatile CheckPoint TOC Sensor won Instrument Business Outlook's (IBO) 2008 Gold Award for best portable instrument design.

The CheckPoint Pharma's and CheckPointe's light weight, ultra portability, battery power option, and continuous monitoring capability make it ideal for a wide range of uses in the semiconductor, microelectronics, pharmaceutical, power and other industries. Typical applications include:

  • Rapid diagnostic sampling, trending, and troubleshooting
  • Continuous on-line monitoring
  • Process monitoring
  • Portable check in semiconductor manufacturing

The GE CheckPoint Total Organic Carbon (TOC) Sensors let you monitor TOC on-line or sample TOC anywhere, anytime. Key features and benefits include:

TOC Monitoring Versatility and Convenience

Depending on your needs, CheckPoint Pharma or CheckPointe can be used for continuous on-line monitoring, rapid on-line monitoring, or grab sampling.

Ultra Portability

The Sievers CheckPoint TOC Sensors takes portable TOC analysis to a new level with its optional battery operation. The CheckPoint TOC Sensors can operate four or five hours using the battery, or continuously with AC power. Weighing just 3.6 kg (7.9 lb) with battery, CheckPoint gives you the freedom to sample TOC anywhere, anytime.

Rapid Analysis

CheckPoint TOC Sensors provide the rapid results and fast rinse down required for time-critical diagnostics and troubleshooting. Featuring a default measurement every 15 seconds, users can adjust output intervals up to 8 hours.

Easy to Use with Low Maintenance

The reagentless CheckPoint Sensors are easy to operate and require minimal maintenance. is typically stable for six months.

Pharmaceutical Regulatory Compliance

The new, economical CheckPoint Pharma TOC Sensor is designed for pharmaceutical applications, and has a Standard Operating Procedure (SOP) that meets minimum United States Pharmacopeia (USP), European Pharmacopeia (EP), Chinese Pharmacopeia (CP), and Indian Pharmacopeia (IP) requirements.
