"Hanna HI-97700 Ammonia LR Photometer\r\nThe HI-97700 has an innovative optical system that offers superior performance in accuracy, repeatability, and the short amount of time it takes to perform a measurement. This compact, waterproof meter is extremely user friendly with a tutorial mode that walks the user graphically, step by step, in performing a measurement.\r\n\r\nThe use of a backlit dot matrix LED allows the use of virtual keys which makes the operation of the meter very intuitive including selecting different methods, reviewing GLP data, recalling the last 50 measurements, and customising the meter to user preferences.\r\n\r\nHI-97700 is waterproof including the cuvette holder that is designed with ridges to protect the optical path from getting scratched by the cuvette and a protected battery compartment that holds three AA batteries.\r\n\r\nThe compact design fits comfortably in the hand for use in the field or on a table for benchtop use. The LCD is 71 mm (2.75\") by 37 mm (1.6\") and is backlit for easy viewing under all conditions.\r\n\r\nKey Features of the Hanna HI-97700 Ammonia LR Photometer\r\n\r\n \tMeasures Low Range Ammonia 0.00 to 3.0mg/L (as NH3-N)\r\n \tNo warm up time before taking a measurement.\r\n \tTutorial mode for step-by-step instructions.\r\n \tDisplays results in multiple chemical forms.\r\n \tFully water resistant.\r\n \tCAL Check feature allows performance verification and calibration (CAL Check standards not included).\r\n\r\nSupplied with\r\n\r\n \t2 Cuvettes &amp;amp; Caps\r\n \t2 Plastic inserts for cuvettes\r\n \t3 1.5V AA Batteries\r\n \tInstruction Manual\r\n \tInstrument Quality Certificate\r\n\r\nReagents not included.\r\n\r\nSpecification\r\n\r\n\r\n\r\nRange\r\n\r\n0.00 to 3.0mg/L (as NH3-N)\r\n\r\n\r\nResolution\r\n\r\n0.01mg/L\r\n\r\n\r\nAccuracy\r\n\r\n±0.04 mg/L ±4% of reading\r\n\r\n\r\nLight Source\r\n\r\nLight emitting diode\r\n\r\n\r\nLight Detector\r\n\r\nSilicon photocell with narrow band interference filter @ 420 nm\r\n\r\n\r\nBattery Type/Life\r\n\r\n1.5V AA battery (3 pcs.) / &amp;gt; 800 measurements (without backlight)\r\n\r\n\r\nAuto-off\r\n\r\nAfter 15 minutes of inactivity (30 minutes before a READ measurement)\r\n\r\n\r\nEnvironment\r\n\r\n0 to 50°C\r\n\r\n\r\nDimensions\r\n\r\n142.5 x 102.5 x 50.5 mm\r\n\r\n\r\nWeight\r\n\r\n380g with batteries\r\n\r\n\r\nMethod\r\n\r\nAdaptation of the ASTM Manual of Water and Environmental Technology, D1426 Nessler method\r\n\r\n\r\nReagents\r\n\r\nHI-93700-01 Reagent for 100 tests\r\n\r\n\r\n\r\nReagents: HI-93700-01 Reagent for 100 tests"
