Most of Bluelab EC/ppm equipment does not need calibrating as they are all factory calibrated at Bluelab (except Bluelab EC and ppm Pens).
To ensure solutions remain accurate
If you want to ensure the ongoing accuracy of your Bluelab conductivity products, we advise that you clean and test them on a regular basis. We calibrate all our EC meters and pens in-house. Instead, you should clean your EC probe and then use 2.77 EC solution 500 ml to check that cleaning has been successful. You should aim to clean and test your EC product every 30 days. Furthermore, all our products come with step by step guidelines for cleaning and care.
In addition, the Bluelab Probe Care Kits has everything you need to clean, maintain and test your conductivity equipment, such as EC probe cleaner, a chamois and more. You can also expand your toolkit with our conductivity replacement probes, carry cases and other EC accessories.
