MISCO Digital Handheld Refractometer

Refractometer for Testing Metalworking Fluids & Coolant

Why is metalworking fluid/coolant management often the most neglected portion of the manufacturing process?

Nearly everyone knows the benefits of proper metalworking fluid/coolant concentration, but coolant management often takes a back seat to more pressing matters. But you can only ignore it for so long before you run into trouble.

Before you know it, your speeds and feed are down, tool replacement is up, part quality and surface finish suffer, scrap and re-work is up, employees are complaining of dermatitis, the shop stinks to high heaven from nasty smelling sumps, fire and brimstone are raining down from the skies, rivers and seas are boiling, forty years of darkness, earthquakes, volcanoes, the dead rising from the grave, human sacrifice, dogs and cats living together… you get the idea.

Metalworking fluid/coolant management is often the most neglected portion of the manufacturing process. This is because (here’s the big secret)… no one enjoys measuring metalworking fluid/coolant.

Well, we can’t promise to make the process any more fun, and we can’t twist your arm to make you monitor your fluids, but we can give you an absolute rock-solid and accurate measurement tool for the job. Our refractometer is second to none at measuring tough emulsions and is so rugged your team will have trouble destroying it. Using a refractometer continually to monitor your fluids may not head off a disaster of biblical proportions, but we promise you a MISCO refractometer is the right tool for the job.

How do we know so much about metalworking fluid/coolant? First, we have been selling metalworking refractometers since your grandpa operated a Bridgeport. Second, we work with nearly every major metalworking fluid manufacturer. Most importantly, we use our refractometers in our plant to test the coolant concentration in the machines we use to make our refractometers, which are made right here in the USA!

For continuous, real-time measurement, the IRIS Inline Refractometer provides 24/7 monitoring. Continuous monitoring allows for prompt fluid concentration adjustments and productivity.

Metalworking (2)

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.

Category: Metalworking

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.
