DD H2Ocean Seawater Refractometer

BRIEF DESCRIPTION: When you need absolutely accurate salinity conditions in your aquarium, you're going to need an H2 Ocean Seawater Refractometer. Unlike other refractometers on the market, the H2 Show Refractometer measures "true" seawater salinity levels, instead of just saltwater. This means that it measures usually unaccounted for elements such as calcium and magnesium as well as sodium chloride, giving highly accurate, precise results.
 
  • Shipping Class:  Eligible for FREE Shipping
True calibration of your seawater levels creates the ideal environment for fish to thrive.

Features:
  • Include a finer scale running from 20-40ppt salinity (SG 1.015 - 1.030).
  • 20/20 calibration at room temperature for more consistency and accuracy in everyday use.
  • Full ATC (auto temperature compensation) ranging from 5 to 30 degrees C.


What’s different between the NEW DD H2O refractometer and others you might ask?

Almost all, if not all, of the refractometers currently available to the aquarium hobby are designed for measuring saltwater (sodium chloride or brine solution) and not true ‘seawater’. Although seawater is mostly sodium chloride it also contains other elements such as magnesium and calcium that change the refractive index slightly and will give a slightly different result.

The most common symptom of this difference in refractive index can be seen when mixing up salt as per salt manufacturer’s instructions and achieving a solution strength where it appears, through testing, that the levels of elements are lower than stated by the manufacturer. In actual fact all of the levels are low as the salinity is not as high as the aquarist believes – we have all seen low Ca or Mg for a given SG with almost all brands of salt.

It turns out that a 35ppt solution of true seawater has the same refractive index as a 36.5ppt solution of brine and so when using a brine/salt refractometer the salinity is likely to be low by 1.5ppt. This can be allowed for by the aquarist but only if they are aware of the difference.

After extensive development, D-D’s new refractometer addresses this issue, giving true salinity results when correctly calibrated and greater accuracy than previously attainable.



Shipping

How is my order shipped and what does it cost?

Orders are shipped either by Courier [currently FedEX Ground] or Postal Service --- the choice is yours!

For delivery by Courier, you pay the actual charges based on a 1 kG package [2.2 lbs] shipped via ground service, plus a nominal $1.00 service charge to cover the cost of insurance and packing materials. We pay any additional charges.

For Postal Service (your best value), shipping on orders under $100.00 is $13.95 to most locations in Canada, exceptions noted below. For orders between $100.00 and $150.00 the rate is $9.95, for orders between $150.00 and $200.00 the rate is just $4.95 and for orders over $200.00 shipping is FREE. The more you order the more you save! The delivery standard for this service is between 1 to 7 business days between all major centers.

NOTE: Additional Shipping Charges apply to orders shipped to the NWT, YK, NU and some rural or remote locations in Canada as well as on over sized or heavy items indicated by the - Additional Shipping symbol.

The flat rate shipping cost used as well as our contribution towards that cost, is usually sufficient to cover the cost of shipping however if you are located in a remote or air stage area, additional shippings charges may apply. In those circumstances we'll contact you regarding any addtional cost so you can decide whether to proceed with your order or not. Otherwise we'll just get the order in its way to you.
