OFFThe Next Generation of Digital Refractometers• Extremely water resistant (IP65)
• Can be washed under running water• Will float if accidentally dropped in water• Revolutionary new External Light interference (ELI)feature Patented• When intense light penetrates the prism of a digitalrefractometer, the light waves interfere with thesensor, which may lead to inaccurate
measurements. To ensure accurate measurement
results, the PAL is programmed with the ELIfunction which displays the [nnn] warning message
when intense direct light is detected. Forming ahabit of shading the sample stage with your hand
and re-pressing the START key (when the warning
message from the ELI function is displayed) will
ensure accurate measurement results each time.

water resistant• Ergonomically designed for one-handed operation• The innovative design makes it easy to pour out andremove a sample, but difficult to spill the sample.

• Automatic Temperature Compensation (ATC)Mode• Mode S : Mode S improves repeatability ofsamples that cause inconsistent readings.
TMSModeTM• Measurement history (up to 100 items) can be readby touching a contactless IC card reader / writerconnected to an Android smartphone or a personalcomputer.

• Mode HTM : Mode HTM enables to measure thesample at high temperature in 2 seconds.
