Overview
Misco built this Palm Abbe refractometer to read the freezing point and concentration of glycerine and propylene glycol antifreeze in sprinkler systems. A couple of drops on the prism are all it needs, and a fifth scale reads the refractive index of fire fighting foam.
The five scales cover the common antifreeze types in fire sprinkler work, so an inspector can decide on the spot how much to add. It is a specialist tool, not a general refractometer. Calibration and cleaning steps are not listed.
Who it's for
Fire protection professionals who test glycerine and glycol solutions in the field. Anyone wanting a brewing or salinity scale should choose a different instrument.
Pros and cons
- Five scales in one tool
- Freeze point and concentration readings
- Small sample needed
- Foam refractive index scale
- Cleaning steps not listed
- Specialist scales only
- Calibration procedure missing
Performance notes
A refractometer reads how much light bends through the sample, and each scale translates that bend into a concentration or freeze point for one fluid. Choosing the correct scale for glycerine or glycol is essential. The reading comes from a very small sample.
