Which Calibration Solution do I use first when calibrating a Bluelab pH instrument?
A. If calibrating with pH7.0 and pH4.0, ALWAYS calibrate to pH7.0 first, then pH4.0. If calibrating with pH7.0 and pH10.0, ALWAYS calibrate to pH7.0 first, then pH10.0. Q. Why do we need to clean the probes on Bluelab instruments? A. The instrument is only as accurate as the probes are clean! This is the most important piece of maintenance required on any Bluelab instrument. The probes are what come into contact with the solution and relay the reading back to the instrument for it to be displayed. The probes are susceptible to being contaminated or being covered in a greasy film that inhibits an exact reading. There are no shortcuts to cleaning the probes. It is already a very simple procedure and it will also ensure your instrument measures it right every time.
