Features: 

Easier to use and more accurate than chemical test kits. Ascorbic acid method. ± 0.04 ppm ± 4% of reading accuracy. Large, easy to read digits. Auto shut off. Dedicated to a single parameter. Designed to work with HANNA’ s reagents. Uses 10 mL glass cuvettes.
Small size, big convenience. Weighing a mere 64 g ( 2.25 oz.) , the Checker® HC easily. fits into the palm of your hand or pocket.Use for quick and accurate on the spot analysis. Single button operation: zero and measure. Operated by a single AAA battery.

Ideal for: Aquaculture, natural, waste, drinking waters and agriculture.

Orthophosphates are found in natural and wastewaters. They are commonly added to drinking water as a corrosion inhibitor. The instantaneous analysis of orthophosphate by colorimetric determination provides rapid results using a standard analysis technique.
The HANNA HI 713 Checker® HC bridges the gap between simple chemical test kits and professional instrumentation. Chemical test kits are not very accurate and only give only a few resolution points while professional instrumentation can cost hundreds of dollars and can be time consuming to calibrate and maintain. The HANNA HI 713 Checker® HC is accurate and affordable.

The HI 713 Checker® HC portable handheld colorimeter features a resolution of 0.01 ppm ( 250 points) and ± 0.04 ppm ( mg/ L) ± 4% of reading accuracy. The HI 713 Checker® HC uses an adaptation of Standard Method 4500-P E, Ascorbic Acid method.
The HI 713 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.

Includes: HI 713 Checker® HC is supplied with sample cuvettes with caps ( 2) , powder reagents for phosphate ( 6) , battery and instructions.

Specifications: Range: 0 to 200 ppb. Resolution: 1 ppb. Accuracy: ± 5% of reading ± 10 ppb at 25° C. Method: Adaptation of Standard Method Ascorbic Acid. Supplied with 2 sample cuvettes with caps, 6 powder reagents, AAA battery, and instructions
