Taking a break

 We're taking a break moving shop and hope to be back soon. We will ship orders on 2018-07-25. 

This pH combination electrode is made of sensitive glass membrane with low impedance.It can be used in a variety of PH measurements with fast response, good thermal stability. It has the good reproducibility, difficult to hydrolysis, and basically eliminate the alkali error. In 0 to 14pH range, the output voltage of the electrode is linear. The reference system which consist of the Ag/AgCl gel electrolyte salt bridge has a stable half-cell potential and excellent anti-pollution performance. The ring PTFE membrane is not easy to be clogged, so the electrode is suitable for long-term online detection.
 
Q: How to use it in the Arduino water quality monitoring system?
A: This industial ph electrode can directly work with the sensor board from Analog pH Meter Kit to produce a long-term PH monitoring. And the output voltage feedbak is from 0 to 5v to indicate PH value from 0 to 14.
 
Applications
 
The electrode is suitable for all kinds of printing, circuit board factory, waste water containing chromium and other industrial and domestic sewage pH monitoring.

Use and Maintenance

  • Electrode must be known before the measurement standard buffer solution PH value calibrated to improve the measurement accuracy , PH value of the buffer to be reliable, and the closer the measured value , the better , generally no more than three PH.
  • Sensitive glass bubble ball electrode tip is not in contact with a hard object , any breakage and hair will rub the electrode failure.
  • Electrode receptacle must be kept clean and dry height , if tarnished available medical cotton and ethanol to wipe and dry , definitely prevent the output ends of a short circuit , otherwise it will lead to inaccurate measurements or failure.
  • Measurements should be taken before the bubble inside the glass bulb rejection to , otherwise it will cause measurement errors , measurement, should stir the electrode in the test solution still placed to accelerate response.
  • Both before and after measurements and clean the electrode with deionized water to ensure measurement accuracy , the viscosity was measured in a sample , the electrodes need to use deionized water to remove the solvent.
  • Passivated electrode will produce long-term use , the phenomenon is sensitive to low gradient , slow response , inaccurate readings , then you can lower end of the electrode bulb with 0.1M solution soak for 24 hours ( preparation 0.1M dilute hydrochloric acid : 9ml hydrochloride diluted with distilled water to 1000ml), then use 3Mkcl solution soak for several hours to restore performance.
  • Glass bulb liquid surface contamination or blockage , but also make the electrode passivation , at this time , should be based on the nature of the pollutant , the appropriate cleaning solution.
  • Electrode cycle is about a year, after aging should be promptly replaced with new electrodes.
