As a wine making hobbyist I usually make my own solutions for test using a hydrometer and known Specific Gravity/Brix measure point, and zero my device with distilled water at room temperature. Some wine supply shops sell calibration kits you might be able to use as long as you are in the 0-32 range. Hope this helps, Jeffrey McGlaughlin Engineering Designer Tactical Systems Aerospace Battelle 505 King Ave. Columbus, OH 43201 -----Original Message----- From: TechNet [mailto:[log in to unmask]] On Behalf Of Graham Collins Sent: Thursday, October 10, 2013 12:18 PM To: [log in to unmask] Subject: [TN] calibration of Brix Refractometer Hi TechNet We monitor the concentration of cleaning chemical in our wash system by using a brix refractometer, the question has come up - how do we check the calibration of the refractometer. I'm assuming that one would use a calibration fluid, similar to verifying an Omegameter is working. My questions - what sort of calibration fluid would be most suitable for this? Can anyone recommend a good source? (prefer within Canada, but not essential) Thanks! -- regards, Graham Collins Senior Process Engineer Sunsel Systems (902) 444-7867 ext 211 ______________________________________________________________________ This email has been scanned by the Symantec Email Security.cloud service.
