HANNA, Free And Total Chlorine, Cyanuric Acid And PH Photometer With 555 Nm LED

In swimming pools, spas and similar applications, a single instrument can be used to measure the four most important parameters in pool water testing. This photometer provides a digital readout in seconds with much greater accuracy than comparable test kits, eliminating the problems associated with color interpretations. Unlike other multi-parameter photometers or spectrophotometers the HI 96104 is very simple to operate: just zero your sample, pour the reagents in the cuvet and take a direct reading. The HI 96104 is specifically designed for swimming pool and spa applications. This rugged meter features the four most common parameters for these applications. Range Free Chlorine 0.00 to 2.50 mg/ L Range Total Chlorine 0.00 to 3.50 mg/ L Range Cyanuric Acid 0 to 80 mg/ L Range pH 5.9 to 8.5 pH Resolution Chlorine 0.01 mg/ L Resolution Cyanuric Acid 1 mg/ L Resolution pH 0.1 pH Accuracy Chlorine ± 0.03 mg/ L ± 3% of reading Accuracy Cyanuric Acid ± 1 mg/ L ± 15% of reading Accuracy pH ± 0.1 pH Light Source LED 555 nm Light Life Life of the instrument Light Detection Silicon Photocell Battery Type / Life 1 x 9V / approx. 40 hours of continuous use; auto-off after 10 minutes of non use Environment 0 to 50° C ( 32 to 122° F) ; RH max 95% non-condensing Dimensions 180 x 83 x 46 mm ( 7.1 x 3.3 x 1.8" ) Weight 290 g ( 10 oz.)
