MSFET 3332 pH-ISFET sensor module

pH sensing module with integrated sensor electronics and integrated solid state Ag/AgCl reference electrode packaged onto a miniature PCB. The integrated circuitry drives the sensor via a fixed constant current/constant voltage setting and provides the analogue and digital (SPI) output. The output signal is proportional to the pH value of the measured liquid sample.

Characteristics

  • small size
  • analogue and digital (SPI) output
  • single supply
  • low power consumption (< 10mW)

Key Specifications
  • Typical pH range: pH2 - pH11
  • Typical sensitivity: 55mV/pH
  • Response time: 90% signal level: < 1 sec
