ACCURATE AND AFFORDABLE PHOSPHORUS ULR MEASUREMENT

Phosphorous (as phosphate) can be introduced to
aquaria through feed, decaying plant and animal
waste, and even tap water, so it can quickly become so
abundant that it becomes a nuisance. Phosphate is a
driving factor in excess algae growth, so it is important
to keep levels as close to zero as possible.

The HANN A HI 736 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 736 Checker®HC is accurate
and affordable.

This Checker®HC features an accuracy of ±5% of

reading and uses an adaptation of Standard Method

Ascorbic Acid.

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 736 Checker®HC is extremely simple to use.

First, zero the instrument with your water sample.

Next, add the reagent. Last, Place the vial into the

HI 736 Checker®HC, press the button and read the

results. It’s that easy.
