HI-4000-51 Gas Sensor Replacement pH information

Hanna's extended description

The HI-4000-51 is a gas sensor replacement pH for ammonia sensor.


How it works

A gas sensor works due to the partial pressure of the measured gas in solution. The dissolved gas in the sample diffuses into the membrane and changes the pH in a thin film of unbuffered electrolyte on the surface of the internal pH sensor. Diffusion continues until the partial pressure of the sample and the thin film of electrolyte are the same. The pH change is proportional to the concentration of dissolved gas in the sample solution.



Solutions are available in a variety of sizes. Check whether the solution you require is available in 1 gallon, 500ml, or 230ml bottles, or individual 20ml sachets.
