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.

Apply 1-2 drops onto the prism.

Close the daylight plate. View the scale through the eyepiece.

Read the measurement value where the boundary line intersects the scale.


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.
