Match the scale to the coolant

Measure ethylene- or propylene-glycol coolant concentration with the four-scale MDX-603 digital refractometer.

Match the scale to the coolant

The MDX-603 keeps two coolant chemistries distinct: ethylene glycol and propylene glycol. Select the appropriate chemistry before using its concentration or freezing-point scale. The concentration ranges are 0–65% v/v for ethylene glycol and 0–73% v/v for propylene glycol; the wrong chemistry selection is not a substitute for identifying the sample.

A compact reading station

The stainless-steel prism well sits beneath a cover, with a removable rubber grip around the handheld body. A digital display avoids interpreting a boundary line through an eyepiece. The 15-read continuous-loop function supports repeated observations of the sample; keep the selected scale and reported units with the result.

Set up and check before the sample

The manufacturer specifies zeroing with distilled water and provides a dedicated MDX-603 manual below. Follow that procedure and the temperature-compensation instructions before testing. Concentration resolution is 0.1% with stated accuracy of ±0.5%; resolution is the display increment, not an accuracy guarantee at every operating condition.

Choose the right protection and range

The detecting unit is rated IP67 and the remainder IP65—not a single whole-instrument immersion rating. The case protects the instrument between sessions. Confirm the required freezing-point limits before ordering: the published Celsius and Fahrenheit endpoints are inconsistent, so precise endpoint claims are intentionally withheld here.

Frequently Asked Questions

What does the MDX-603 measure?

Ethylene-glycol and propylene-glycol concentration, plus a separate freezing-point scale for each coolant.

Does one concentration scale cover both coolants?

No. Select the scale for the actual coolant chemistry: ethylene glycol or propylene glycol.

What concentration ranges are available?

Ethylene glycol is 0–65% v/v and propylene glycol is 0–73% v/v.

How is the instrument zeroed?

The manufacturer specifies distilled water; follow the supplied MDX-603 calibration procedure.

Can it take repeated readings?

Yes. Its continuous-loop mode takes 15 readings; use the manual for the operating sequence.

Is the entire refractometer rated IP67?

No. IP67 applies to the detecting unit; the remainder is rated IP65.

What comes with catalog 48603?

One MDX-603 refractometer, rubber grip and prism cover, lined hard case, disposable pipet, battery and manual.
