Marine Master Waterproof Wireless Multiparameter Photometer

The photometer has an advanced optical system that uses a Light Emitting Diode and a narrow band interference filter for accurate, repeatable readings. The optical system is sealed from outside dust, dirt, and water. The meter uses an exclusive positive-locking system to ensure that the cuvettes are placed into the holder in the same position every time. With the CAL Check™ functionality, users are able to validate the performance of the instrument at any time. CAL Check™ cuvettes are certified against NIST-traceable reference instrument(s). The built-in tutorial mode guides users step-by-step through the measurement process. The tutorial mode includes all steps required for sample preparation, the required reagents and quantities. Suitable for field or bench measurements, the photometer features: Test capabilities for 9 parameters using 1 device NEW! Comes with free Hanna Lab app, connects via Bluetooth for easy data tracking, exporting and analysis Sophisticated optical system Meter validation using certified CAL Check™ cuvettes Tutorial mode guides the user step-by-step Option to assign locations to logged readings Auto logging Waterproof IP67. The case and device both float on water. CAL Check TM Validation Hanna’s exclusive CAL Check TM feature provides a stress-free, straightforward way to ensure your photometer is working properly. Simply insert the certified CAL Check TM standards and let your meter guide you through validation. If your photometer is out of specification for any reason, simply calibrate to your standard. On-Screen Tutorials 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. Tank Selection and Multiple Reading Locations Management Users can edit up to 25 different tanks, correlate reading location to any location from the list so that logged data is linked to its reading location. Data Logging Missed a measurement? No need to worry because your photometer will automatically log the last 200 measurements. The results can be viewed instantly using the Log Recall Menu. Advanced Optical System A Light Emitting Diode (LED) provides more light while using less power and a narrow band interference filter results in more accurate and repeatable readings. Large Cuvette Size The 25-mm path length cuvette allows light to pass though more of the sample ensuring accurate measurements even in low-absorbance samples. Positive Locking System Cuvettes are placed into the holder in the same position every time by ensuring that the notch on the cap is positioned securely in the cell’s groove. Portable Design Made to fit comfortably in your hand for on-the-go testing or sit on a table for benchtop use, a backlit LCD display provides at-a-glance readings from any angle, day or night. The supplied AA batteries provide life for more than 800 measurements.
