General Features Waterproof casing The casing oers IP67 waterproof protection and oats. Advanced LED optical system LEDs have a much higher luminous e¤ciency, providing more light while using less power. They also produce little heat, which could otherwise aect electronic stability. CAL Check™ functionality Hanna’s exclusive CAL Check feature allows for performance veri¡cation and calibration of the meter using NIST traceable standards. Our CAL Check standard vials are developed to simulate a speci¡c absorbance value at each wavelength to verify the accuracy of subsequent readings. The CAL Check screen guides the user step-bystep through the validation process and user calibration. Multiple measurement methods Users can select the use of powder reagents supplied in packets or the use of liquid reagents supplied in a dropper bottle. Built-in reaction timer Waiting the proper reaction time is of key importance when performing colorimetric measurements. The countdown timer displays the time remaining until a measurement will be taken, ensuring consistent results between sample measurements and users. Large cuvette size The sample cell of these photometers ¡ts a round, glass cuvette with a 25 mm path length. The relatively long path length of the sample cuvette allows the light to pass through more of the sample solution, ensuring accurate measurements even in low absorbance samples. The cuvette holder features ridges to protect scratching of the optical path by the cuvette. Intuitive dot matrix display These photometers are designed with a backlit, graphic LCD. With virtual keys, a battery status indicator, and error messages. Users will ¡nd the interface intuitive and easy to read. GLP data Good Laboratory Practice (GLP) shows the date and time of the last user calibration. Auto logging Log and recall the last 50 measurements. Dedicated help A dedicated help key provides information relating to the current meter operation, and can be used at any stage in the setup or measurement process to show contextual help. On-screen tutorial mode with animations The built in Tutorial mode guides users step-by-step through the measurement process. Error messages Messages appear on the display alerting to problems such as out of range, light low, light high, ambient temperature out of limits, and battery low. Auto-o protection These meters use three AA batteries that allow for about 800 measurements to be taken. The auto-o feature automatically shuts o the meter after 15 minutes of inactivity in order conserve battery life. Battery status indicator Indicates the amount of battery life left. 10 Photometers 10.63 www.hannainst.com | portable
