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
- For cellphones, download NFC reader app or turn on the NFC feature. For computers, connect the NFC reader.
- Place NFC reader to the PAL device.
- 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 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. |

| PAL-91S, easily measure the coolant in brine and other agents of Ethylene Glycol.Antifreezing solution (coolant) whose main ingredient is ethylene glycol is widely used as mixed in cooling water of car's radiator, as cooling medium for central air - conditioning system, freezer / refrigerator, cooling coil, cooling fixture etc. The higher the concentration is, the lower the temperature at which ethylene glycol is frozen is. Therefore, it is needed to adjust freezing temperature of antifreezing solution so that it dose not freeze under a specific operation temperature.For Prolylene Gycol, please choose PAL-88S |
The long-awaited "Pocket" digital and compact sized PAL-RI was released.When the start key is pressed after placing some droplets of sample on the prism, the Refractive Index (resolution 0.0001) and temperature °C of the measurement will be displayed continuously.
|
PAL-BX/RI has dual scales of Brix full range : Brix 0.0 to 93.0%, high measurement accuracy : Brix ±0.1% and Refractive Index (resolution 0.0001). RI and measurement temperature will continuously scroll across the display. The PAL-BX/RI works perfectly for measuring almost any sample.

This is most suitable for the measurement of the percent dilution and controlling the percent concentration of hydraulic oil and cleaning liquid. Cutting oil, molding lubricant and rust resistance liquid are also well within the measurement range of the PAL-102S. With a water resistant design, the PAL-102S can also float in water which will help to prevent unforeseen accidents. Quick and easy measurements can be taken with the PAL-102S anywhere on your factory floor. | PAL-03S is suitable for measurement of salt water(g/100g).This model is also used as the important management tool of the spraying the snow-melting agent on the road | The unit displays the non-fat solids contained in milk. The unit is equipped with a scale that corresponds to measurement values obtained from ultrasonic milk analyzers, allowing the non-fat solid contained in milk to quickly be determined. |
This model can be used for determining the quality of colostrum to protect and nurture the health of your livestock and newborn calves! The ideal colostrum (first milk) Brix level is 20% and above.It measures the Brix value of colostrum, which has a correlation with the immunoglobulin (IgG) value contained in colostrum. If the Brix value of the colostrum is over 20%, you can safely assume it is high-quality colostrum. ※Correlation coefficients may vary depending on the species of animal. |
This is ideal to measure Hydrogen peroxide concentration commonly used as a disinfectant | |
