pH Sensor, BNC Interface, 0-14pH US$28.18

9328
pH Sensor, BNC Interface, 0-14pH


pH Sensor

This pH sensor is a combination electrode that provides a voltage proportional to the pH of the tested solution, with pH 7 corresponding to the voltage reference of 2.048V of the circuit (assuming connection to a Waspmote system), with an uncertainty of 0.25pH. The value is obtained by reading the output voltage with an analog-to-digital converter, then performing a conversion routine to get a pH value.

To get an accurate value from the sensor, it is necessary both to carry out a calibration and to compensate the output of the sensor for the temperature variation from that of the calibration moment.

pH Sensor Features

  • Type: Combination electrode
  • Range: 0 to 14 pH
  • Operating Temperature: 0 to 80 C
  • Zero Electric Potential: 70.25p
  • Response Time: Less than 1 minute
  • Internal Resistance: ≤250MΩ
  • Repeatability: 0.017
  • PTS: Greater than 98.5
  • Noise: Less than 0.5mV
  • Alkali Error: 15mV
  • Reader Accuracy: Up to 0.01 (when calibrated)

Compatible with Waspmote

This sensor can be used in a Waspmote wireless sensor platform by plugging it into the Waspmote Smart Water Sensor Board. The Smart Water Sensor Board includes an adapter from BNC to RP-SMA so you can connect this sensor to it.
