Atago 2493 Salinity and Specific Gravity Hand-Held Refractometers, MASTER-S/MillM MASTER series , Salinity : 0 to 100‰ Measurement Range
This instrument measures the salinity and specific gravity of seawater, and utilizes a new material that is durable against salty samples, The salinity of seawater is displayed in parts per mill (‰). The MASTER-S/MillM is a good alternative choice when the water resistant feature is not a priority and the Temperature Compensation will be carried out manually.For the model with Automatic Temperature Compensation please choose MASTER-S/Millα.
Application

How to choose suitable model?
Step❶
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
Step❷
Please select the material
⒈ Metal body : Die-cast aluminium, 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
Both the α and T types are equipped with the Automatic Temperature Compensation feature. Choose the α type for the added feature of IP 65 water-resistance. The H type is the heat-resistant version of the α type.
![]() | The concept of a washable hand-held analog unit is exceptional. After measuring, the instrument can be cleaned with running water under a faucet. The new structural design of these units allows them to be washed whenever necessary. Rated IP65 (dust tight and water resistant). | ![]() | Sample size 2-3 drops. |
![]() | The newly designed ATC system allows the MASTER series to read more accurately than any comparable unit. ATAGO has applied for a patent on the design of the improved ATC system. The MASTER series reads more accurately than any comparable unit in the market.The Automatic Temperature Compensation function of the MASTER-α, T, H series enables you to take measurement readings regardless of the ambient temperature. | ![]() | ATAGO has developed a spoon-shaped tip that automatically spreads the sample across the prism. This makes the instrument even more user-friendly. saving valuable time. |
![]() | 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-coloured samples. Even when measuring milky-coloured, 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.
