Key Benefits


Cost Effective ―The CheckPoint sensors use the simple TOC methodology of measuring initial sample conductivity, UV oxidation of organics, and a final, post-UV con- ductivity measurement (Direct Conductometric). They provide a reliable low-cost TOC approach useful for pharmaceutical Purified Water (PW) and Water for Injection (WFI) and semiconductor ultrapure water (UPW) monitoring applications.
Rapid Analysis ― The two sensors provide the rapid results and fast rinsedown required for time-critical diagnostics and troubleshooting. Featuring a default measurement every 15 seconds, users can adjust output intervals from 15 seconds up to eight hours.
Easy to Use with Low Maintenance ― The reagentless CheckPoints are easy to operate and need minimal maintenance. Calibration is typically stable for six months.
Sensor-to-Sensor Matching ― The sensors can be calibrated to areference TOC instrument, allowing excellent low-level TOC sensor-tosensor matching.
Pharmaceutical ― The CheckPoint Pharma provides pharmaceutical manufacturers with a cost-effective and flexible process monitor for
process trending, screening potential trouble areas, and diagnosing problems in real time. The CheckPoint Pharma can be placed at a dedicated
point of use or conveniently moved throughout the pharmaceutical manufacturing facility for multi-point water monitoring, diagnostics, and troubleshooting. The CheckPoint Pharma comes with a simple and convenient Standard Operating Procedure (SOP) to meet installation,
operation, and performance qualification requirements.
Hard Disk, Thin Display, and Semiconductor ― The CheckPointe’s low cost and portability gives microelec- tronics manufacturers new
problem-solving and diagnostic capabilities. In addition to providing contin- uous on-line TOC monitoring to detect critical ultrapure water
changes, the CheckPointe sensor makes it possible to quickly check TOC samples from pressurized or non-pressurized sources. CheckPointe
can also monitor UPW distribution points or fab tools for potential contamination sources.
Power (UPW, Cation Conductivity Control, Makeup, or Cogeneration Condensate Polish Control) ― The CheckPointe provides sensitive detection of trace organic contamination in power feed and loop UPW. Controlling cation conductivity can be difficult if its source is non-ionic organics. High pressures and temperatures in power plant water cycles can oxidize Cl, S, or N containing non-ionic
organics to extremely corrosive hydrochloric, sulfuric, or nitric acids. The CheckPointe has an enhanced response to these compounds
and can rapidly indicate their presence in makeup or con-densate water. Rapid detection of other UPW system problems is easy with
CheckPointe’s ultra portability and diagnostic features.
