Hanna Instruments

Anyone heard of Hanna Instruments?

Apparently they have probes for detecting ammonia, nitrite, nitrate, phosphate etc...

no need test kits anymore. but kinf of ex.

Wow! how much ???

USD216.90 excluding shipping.

Says they have 25% off. dont know if this price is already discounted

here's some writeup

------------------------------------------------------------------------------

Nitrates are present in nature as a result of the decomposition of organic microorganisms or due to their use as fertilizers.

Nitrates reduce to nitrites, which in turn easily combine to form substances dangerous to man.

A maximum level of 45 mg/L is established as a worldwide guideline for nitrate concentration in water.

In Europe, the maximum consented level of nitrates in potable water is 50.0 mg/L, while in the USA the EPA has established a guideline for the maximum level of nitrate nitrogen of 10 mg/L (NO Π3 -N), which corresponds to 45.0 mg/L of nitrates.

The HI 93728 kit provides you with all you need for measurement:

photometer and reagents.

Hanna offers the NITRATE HI 93728

with a range of 0.00 to 30.0 mg/L,

resolution 0.01 mg/L

Accuracy (@20°C/68°F) ±0.5 mg/L ±10% of reading

HI 93728 Kit includes 2 cuvets, caps, 9V battery and instruction manual.

This is even more cool!

THE MULTIPARAMETER ION SPECIFIC BENCH METER

With the ever-increasing depletion of fish stocks in the open seas, aquaculture has gained prominence and can prove essential to our future dietary needs.

Monitoring and controlling parameters such as the oxygen level as well as pH and nitrate content in water is vital in ensuring a profitable fish production.

An accurate control program can prevent disease, increase production and even reduce the premiums on crop insurance.

Research personnel, fish farm operators and wildlife specialists now have one compact and easy-to-use meter to keep a close tab on the most important parameters in aquaculture.

Simply take a sample of the aquarium water and place it in the unit to be zeroed.

Add reagents to it and place it back in the C 203.

The meter will then show you the relevant value in mg/L or µg/L in clear digits on a large LCD.

No need to match colors, calibrate probes or change membranes.

C 203 is supplied with 2 cuvets, caps, 9V battery, 12 VDC power adapter & instruction manual.

Hanna Instruments are analytical grade stuff that we use in labs. Unless you got loads of $$$, don't buy them cause we don't need that kind of accuracy. If you insist then, all I can say is that they are good.

The photometric type just replaces your eye in differentiating the colour, quite similar to what diabetics will use to measure blood sugar levels. The probe type ones need replacement every six months to a year.

Wish they had a calcium probe.

Hi TTboy,

i saw rainbow selling the Hanna phoshate test kit. titration type. didn't bother to ask after i saw they elling their live rock at $25 a kg!

U can get Hach also. Very accurate also. Intial investment is ard $120 for 1 type of testkit cos it comes with the titration kit. Subsequently,you just need to pay ard $10 - 20 for refilling the reagent.

Wonder if singapore got La Motte anot?
