Atago PAL-Plato , Plato and Temperature PAL Series Refractometer 4590 Plato : 0.1゚P Plato : 0.0 to 30.0゚P Temperature : 10 to 75゚C Plato : 0.1゚P Temperature : 0.1゚C PAL-Plato 100 £400.00 2 + -


The PAL-Plato is designed for breweries to measure the specific gravity of sweet wort in degrees Plato.Advantages of the PAL-Plato include : Two buttons for easy operation, an LCD screen for objective readings, and Automatic Temperature Compensation up to 75ºC (212ºF)! Additionally, taking measurements with the PAL-Plato only requires a few drops of sample, and it provides accurate readings within 3 seconds!

A refractometer is a device that measures the total concentration of liquids using the refraction of light. As distilled beverages consist mainly of alcohol and water, the concentration of alcohol can be measured by a refractometer. Brewed beverages contain also sugar. Measuring them without distilling will give an inaccurate reading, as the value of sugar will be added to that of alcohol. Please distill brewed beverages before measuring.

PAL commitment 

A new ergonomic design for comfort and ease of use! In pursuit of an "easy to use" , "easy to operate" and ergonomic architecture of new instruments, ATAGO has achieved a "palm fitting" masterpiece as well as unit that is high in hygienic properties. By reducing the number of unnecessary assembly parts, we have reduced the risks of a germ reproductive environment. Through our efforts to produce a hygienic instrument to be used in any industry, these units are designed to be completely washable. The new PAL series has been approved by the HACCP, and are equipped with the new ELI feature, which ensures accurate measurements - even outdoors. Requests from our customers worldwide are reflected in the development of the new PAL units

ATAGO Releases NFC (Near Field Communication) Equipped Refractometers

In addition to the Bluetooth enabled refractometers, ATAGO ® released refractometers with near-field communication (NFC) technology for the ease of storing and sharing data with phones, tablets, laptops, and other NFC-equipped devices. Simply by tapping NFC-equipped devices, up to 100 measurement data with the date and time are transferred in a matter of seconds. The NFC solution is simpler and prevents typical human errors in data collection and data generation.

With ever evolving movement of profound change in how human interact with machine automation, this upgrade seizes one’s time to write down measurements with a pen or paper.

How to Use NFC Feature on PAL:

Quick and easy three steps

  1. For cellphones, download NFC reader app or turn on the NFC feature. For computers, connect the NFC reader.
  2. Place NFC reader to the PAL device.
  3. Download data.


 Measurement Methods in 3 easy steps

Apply 2-3 drops on the prism surface.

Press the START key.

Measurement value and prism temperature are displayed in 3 seconds!

Other Features

Light & Compact, 100g. Ergonomically designed for one-handed operation.The innovative design makes it easy to pour out and remove a sample, but difficult to spill the sample  Sample size 2-3 drops.
The speedy performance of the PAL is amazing. Simply put a drop of a sample on the prism surface and press the START key. The Brix value ( sugar content / concentration ) will be displayed in just 3 seconds. High temperature sample can be measured.
Protection class of the PAL is IP65. You can rinse off the sample by running water on the sample stage. The design allows the user to easily wipe off the sample. Will float if accidentally dropped in water  Revolutionary new External Light interference (ELI) feature Patented

When intense light penetrates the prism of a digital refractometer, the light waves interfere with the sensor, which may lead to inaccurate measurements. To ensure accurate measurement results, the PAL is programmed with the ELI function which displays the [nnn] warning message when intense direct light is detected. Forming a habit 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
The sample stage is designed to keep sample solutions from spilling out. Calibration with water only.
The Automatic Temperature Compensation function of the PAL enables you to take measurement readings regardless of the ambient temperature. Convenient Storage case.
New Digital Hand-Held "Pocket" Meter for PAL-Series Equipped with NFC Data Transmission Function Data history can be accessed by bringing PAL-NFC to any Android devices or PC-linked USB NFC Reader.

Mode S™  -  improves repeatability of samples that cause inconsistent readings.

Mode H™  : Mode H enables to measure the sample at high temperature in 2 seconds.
