Compact and easy to carryCalibration with water

This refractometer has an exclusive scale for measuring specific gravity of battery fluid and forchecking the freezing temperature of ethylene glycol and propylene glycol which are used as antifreeze mixture in automobiles, thermal catalyst for solar power systems and other industrial applications. MASTER-BCF is the successor model to the conventional BC-3E. The scale is graduated in ゚F. NEW material (which is durable for salty and acid sample) is adopted.




This new type of Hand-held Refractometer MASTER functions such as Easy-to-Read, Easy-to-Hold, Smooth sampling, Easy disposal of sample from the edge, the improvement of hygiene aspect by employing the new type of grip, and well balanced structure, emphasis is also placed on its design, well exemplified by the streamlined body and the strong grip with rich texture.

How to choose suitable model?


⒈ Please select category, suitable samples or measurement range from the list of MASTER series
⒉ If you are not sure the range of your sample, please refer to our data book


Please select the material

⒈ Metal body : Die-cast aluminum, Ideal for the agriculture industry, metal working fluids and various high-temperature samples
⒉ Plastic body : PBT (Polybutylene terephthalate), resistant to salty and acidic samples


Please select features
  • α : Water resistant (IP65)
  • T : Automatic temperature compensation (ATC)
  • M : Low cost model without the above function
  • S : Suitable for Milky sample
Protection class of the MASTER-α, H series are IP65. You can rinse off the sample by running water on the prism. The design allows the user to easily wipe off the sample.Sample size 2-3 drops.
The Automatic Temperature Compensation function of the MASTER-α, T, H series enables you to take measurement readings regardless of the ambient temperature.Automatic Sample Distribution (ASD)
New prism housing design allows for sample to cover the prism without having to lift the day-light plate! This design will allow for fast & easy measurements.
Convenient Storage case.  

The MASTER series has been improved with a clearer, brighter field of view and made even easier to carry.


Compact Redesign of the MASTER Series (from October 2014)
The MASTER series has been improved with a clearer, brighter field of view and made even easier to carry.
These improvements in our newly compact redesigned models are especially clear when taking measurements in dim lighting, or measuring darkly-colored samples. Even when measuring milky-colored, opaque, or oily samples, the boundary line remains crisp and clear.
Note: The size of the scale has changed. It may take some time to re-adjust to the new field of view when reading measurements.
