EZO ORP Circuit for Arduino (Oxidation-Reduction Potential) , Electrochemical Sensing Circuit

This highly compact ORP monitoring circuit fits into any breadboard and is simple to use. Communication with the ORP-3 Circuit is done using only 9 simple commands through an asynchronous serial connection. The Atlas Scientific ORP Circuit provides scientific grade readings to any embedded system that has an RS­232 connection interface.

Features :

  • Oxidation-Reduction Potential circuit is a commonly measured electrochemical parameter used in fish tanks, swimming pools, hydroponic gardening, pollution monitoring and general chemistry.
  • ORP circuit is compatible with any microprocessor that supports UART(Universal asynchronous receiver/transmitter) & I2C(Inter-Integrated Circuit) protocol.
  • Atlas Scientific brings you the power and flexibility of a laboratory grade ORP meter, designed exclusively for robotics.
  • EZO ORP Circuit has a flexible calibration protocol, allowing Single point calibration to any off the shelf calibration solution.
  • Calibration required only once per year with OR probe, sensor & electrode. This device does not include a ORP probe, sensor & electrode.
  • This ORP Circuit, offers the highest level of stability and accuracy.
  • Data format is ASCII
