Hanna Instruments which makes great products like Hanna Checkers is getting official with their new Marine Alkalinity checker. If you haven’t yet realized , this is going to be so awesome. We can’t tell you how many times we’ve squinted at old school (titration) test kits. We’ve confirmed that pre-orders have started for online retailers, however Hanna has started to take pre-orders direct from their website with a initial cost of $49.50. What’s more though, is that the reagents will be sold for $9 for 25 tests breaking down to about $.36 each test. Not too shabby for accurate test results that won’t make you go blind. Hit that read link below to place a pre-order, they will start shipping in 6-8 weeks from today.
Alkalinity is one of the most important parameters to
measure in salt water aquaria. It helps maintain a
stable pH, an important factor for most aquatic life. In
seawater, bicarbonate is by far the largest contributor
to alkalinity. Alkalinity is measured instead of
bicarbonate levels, which are otherwise quite difficult
to determine. Bicarbonate is a critical element, as
corals must have a ready supply of carbonate and
bicarbonate to form their skeletons. Without an
adequate level of alkalinity, therefore, healthy coral
growth is not possible. The alkalinity of natural
seawater is typically 125 ppm CaCO3 equivalents
(7 dKH). The generally accepted alkalinity range in
marine aquaria is 125 – 200 ppm CaCO3 equivalents
(7 – 11 dKH). Some corals may benefit from even
higher alkalinity levels; however, at high alkalinity,
calcium will precipitate out as calcium carbonate,
an undesirable outcome.
The HANNA HI 755 Checker®HC bridges the gap
between simple chemical test kits and professional
instrumentation. Chemical test kits are not very
accurate and only give 5 to 10 points resolution while
professional instrumentation can cost hundreds of
dollars and can be time consuming to calibrate and
maintain. The HANNA HI 755 Checker®HC is accurate
This Checker®HC features an accuracy of ±5%
of reading ±5 ppm and uses the colorimetric method.
The contoured style of this Checker®HC fits in your
palm and pocket perfectly and the large LCD is easy to
read. The auto shut-off feature assures the battery
life will not be drained if you forget to turn it off.
The HI 755 Checker®HC is extremely simple to use.
After zeroing the instrument with your water sample,
add the reagent to the cuvette and shake. Then insert
the cuvette into the HI 755 Checker®HC and start the
timer. Invert the cuvette when prompted and press
the button to read the results. It’s that easy.
