How do I dispose of my pH sensor?

There is 0.23 g of silver metal in our pH sensor and 0.002 mg/L AgCl. These are both under the federal limits of waste disposal but please check your state's regulations.

Therefore, there is no hazardous chemical in the sensor limiting you from throwing it in the trash. Check with a local recycling center for information about recycling some of the electronic components of the sensor or check:

We have also found two other sites that do something similar, but found them more difficult to navigate:
http://www.electronicsrecycling.org
https://www.epa.gov/recycle/electronics-donation-and-recycling
