MISCO Refractometer Q&A Forum
Find answers to many common questions concerning applications, operation, calibration, and maintenance of refractometers:
Looking for a refractometer to test metalworking fluids for grinding at concentrations from 0.5 to 4%, current analog scale 0 – 15% is too large and we cannot see concentration movements – have you got anything?
Often times when measuring metalworking fluid and emulsions with a traditional analog refractometer, either the resolution is not fine enough or the shadow line is too fuzzy. The best solution for metalworking fluids and emulsions is the MISCO Palm Abbe PA201 digital refractometer. The Palm Abbe refractometer has a Brix scale from 0 to 56 Brix, which is way more range than you need, but the precision is +/- 0.1 Brix. The Palm Abbe is a great instrument for measuring emulsions that are too fuzzy to read on a traditional analog refractometer. The Palm Abbe refractometer can also be programmed with the correction factor for your fluid so that you can read the concentration directly without the need for manual conversions.
I have a customer who has a PA 201 Palm Unit & is using one of our metalworking coolants that has a 3.11 Brix multiplier. He wants to have it calibrated with the Brix multiplier factored in, so that his technicians will read the true concentration as having to use a multiplier. Can this be done and if so, where does it need to be sent? What is the cost for this upgrade? What other information is needed prior to shipment back to MISCO?
We can program any multiplier or factor for a metalworking fluid into the Palm Abbe digital refractometer so that you can directly read the concentration of a metalworking coolant or fluid. This can be done at the time of order or the refractometer can be returned to us for reprogramming.
