ACCURATE AND AFFORDABLE PHOSPHOROUS 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 HANNA 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.
HI 736 Checker HC is supplied with (2) sample cuvettes with caps, (6) powder reagents for phosphorus, (1) 1.5V AAA battery and instructions.
