Control salt with this innovative and convenient measurement method

Salt concentration 10.0% Features Offset Function Digital Model

PAL-SALT is widely used in various industries for food and industrial solutions. For food products, in addition to checking salt content, the salt meter is used to make sure salt is properly added and not forgotten for such products as bread, rice balls, and frozen. For industrial use, the salt meter is widely used for salt resistance tests for cars and such.

*Offset feature use examples

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:
Step 1) For cellphones, download NFC reader app or turn on the NFC feature. For computers, connect the NFC reader.
Step 2) Place NFC reader to the PAL device.
Step 3) Download data.
Quick and easy three steps

Measurement Method in 3 Easy Steps

Apply 2-3 drops onto the sensor sectionStartPress the START keyMeasurement value is 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 samples can be measured.
The 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.

*The Certification Mark is a trademark or registered trademark of NFC Forum, Inc. in the United States and in other countries.
Mode S™  -  improves the repeatability of samples that cause inconsistent readings.

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

Common Applications

  • Checking the brine content in Smoked Salmon (requires sample preparation with distilled water)

Long-lasting salt meter - Durable titanium electrode

Uses a titanium electrode that is highly resistant to corrosion from saltwater and seawater.  Long-lasting and durable.Is not damaged by friction and can withstand harsh usage in the kitchen or at factory sites.

Stable reading  - Apply just a few drops of sample on the sample stage

Salinity can be measured by placing a few drops of sample on the sample stage. The measurement stability is not affected by substances containing oil or substances at a high temperature. Measuring without inserting the salt meter into the sample is more sanitary.

Easy calibration for reliable results - Zero Setting & Reference Setting

One press of ZERO buttons to zero set with air. Additionally, 2.50% saline solution allows for testing a known point. Unlike disposable salt meters, the PAL-SALT gives reliable stable measurement results.

Why measure salt content?

Adding salt is one of the most critical processes in food manufacturing as it has a significant effect on the colour, taste, and texture of food.

ATAGO salt meters are ideal for quick and easy salinity checks on the production floor.

Recently, in addition to use in the production are, many companies are validating our salt meters as the preferred method in a lab setting as well. Food scientists are choosing to limit the use of precipitation titration with harmful sliver nitrate (Mohr's method).

Because ATAGO salt meters are sage, fast, and simple.

Due to the difference in measurement principles, reading from the conductivity salt meters may not match up exactly with the reading by titration for certain samples. However, by creating a conversion table between the two testing methods, the correlation between the set of results can be seen.

Unlike titration, no expensive and harmful chemical is involved in the measurement process.

ATAGO delivers a revolutionary salinity measurement solution that is both eco-friendly and cost-effective.
