Specifications HI97115 pH, Alkalinity, Ammonia, Calcium, Magnesium, Nitrate LR, Nitrate HR, Nitrite ULR, and Phosphate ULR Marine pH Range 6.3 to 8.6 pH Resolution 0.1 pH Accuracy ±0.2 pH of reading at 25 °C Method colorimetric adaptation of the Phenol Red Method LED 525 nm Marine Alkalinity Range 0.0 to 20.0 dKH Resolution 0.1 dKH Accuracy ±0.3 dKH ±5% of reading at 25 °C Method Colorimetric Method LED 610 nm Marine Ammonia Range 0.00 to 2.50 ppm (as NH²) Resolution 0.01 ppm Accuracy ±0.05 ppm ±5% of reading at 25 °C Method adaptation of the Salicylate Method LED 610 nm Waterproof and oating IP67 meter design Option to select measurement location for better tracking consistency CAL Check™ validation and calibration Validate instrument performance at any time using Hanna® CAL Check cuvettes certi¡ed against NIST-traceable reference instrument(s). The CAL Check screen guides the user step-by-step through the validation process and user calibration. GLP data displays the last calibration date. Backlit LCD and on-screen help Built-in reaction timer that ensures consistency between tests. On-screen tutorial mode with animations The built-in tutorial mode guides users step-by-step through the measurement process. It includes all steps required for sample preparation, the required reagents, and quantities. Tutorial mode can be enabled or disabled from the setup menu. Includes auto-data logging features to easily record water testing results The instrument features a data autolog function to help users keep track of all measurements. Every time a measurement is made the data is automatically saved. The data log can hold 200 individual measurements (data points). When the log is full, the instrument rewrites the oldest data point. Positive locking system The Hanna positive-locking system ensures cuvettes are placed into the holder in the same position every time. 10 Photometers 10.104 | www.hannainst.com portable
