The MASTER-SUR/NM is designed for clinical purposes: "Serum Protein", "Specific Gravity of Urine" and "Refractive Index". The plastic body model is designed to be resistant salty and acidic samples. The MASTER-SUR/NM is a good alternative choice when the water resistant feature is not a priority and the Temperature Compensation will be carried out manually. Not equipped with the Automatic Temperature Compensation feature.
How to choose suitable model?
Step❶
⒈ Please select category, suitable samples or measurement range from the list of MASTER series⒉ If you are not sure the range of your sample, please refer to our data book
Step❷
Please select the material⒈ 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
Step❸
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.
