Overview
Applying a few drops of sample to the prism and pressing start is the whole routine of this digital refractometer. The PAL-39S is a compact special-scale model whose scale is set for hydrogen peroxide.
A sealed, rated housing makes it usable indoors and in the field, and cleanup is a rinse. The digital display removes the reading errors that come with handheld optical models. Range, resolution and accuracy are not given.
Who it's for
Technicians and lab staff who test hydrogen peroxide solutions at the bench or on site. Anyone testing other fluids needs a refractometer with the matching scale.
Pros and cons
- Special hydrogen peroxide scale
- Rugged IP65 rated design
- Easy rinse cleanup
- Single special scale only
- Range and accuracy not listed
- Sample must reach the prism
Performance notes
A few drops spread over the prism let the instrument read the concentration of the sample, which it shows within seconds after the start key is pressed. Nothing has to be interpreted against a printed scale. The listing does not describe temperature compensation.
