Product Tophit CPS491D

The CPS491D is a digital ISFET sensor (ion-sensitive fieldeffect transistor) with Memosens technology for long-term stable pH measurement in media with high dirt loads. The non-glass sensors in the Tophit line can even be installed overhead. They are characterized by their extremely stable PEEK shaft and can be used in media with high organic solvent parts.

Your benefits:

• Resistant to breaking
  - Sensor body made completely of PEEK
  - Direct installation into the process, reduces effort and costs for sampling and laboratory analysis
• Double-chamber reference system:
  - Poisoning resistant
  - Polyacrylamide free gel
• Application possible in heavily soiled media
• Application possible at low temperatures
  - Short response time
  - Constantly high accuracy
• Longer calibration intervals than glass electrodes
  - Lower hysteresis with alternating temperatures
  - Low measuring error after high-temperature loading
  - Almost no acid and alkaline errors
• With built-in temperature sensor for effective temperature compensation

Further benefits offered by Memosens technology:

• Maximum process safety through contactless inductive signal transmission
• Data safety through digital data transmission
• Easy handling due to storage of sensor-specific data
• Predictive maintenance possible thanks to registration of sensor load data

• Process applications with:
  - Quickly changing pH values
  - Alternating temperatures and pressures
• Water purification and wastewater
• Media with high dirt loads:
  - Solids
  - Emulsions
  - Precipitation processes

With ATEX, FM and CSA approval for application in hazardous areas.
