Use for quick and accurate on the spot analysis
Single button operation: zero and measure
Operated by a single AAA battery

Ideal for aquaculture (marine applications)

Phosphorus concentration in water is monitored because it causes corrosion when present in excessive levels.

The HANNA HI 736 Checker^®HC bridges the gap between simple chemical test kits and professional instrumentation. The HANNA HI 736 is both accurate and affordable.

The HI 736 Checker^®HC portable handheld colorimeter features a resolution of 1 ppb and ±5 ppb ±5% of reading accuracy and uses an adaptation of Standard Method Ascorbic Acid.

The HI 736 Checker^®HC is extremely simple to use. First, zero the instrument with your water sample. Next, add the reagents. Last, place the vial into the Checker^®HC, press the button and read the results. It’s that easy.
