Hanna Instruments Copper High-Range Portable Photometer

This meter offers a superior optical system that utilises a reference detector and narrow band interference filters for extremely fast and repeatable measurements.
No warm up time before taking a measurement
Tutorial mode for step-by-step instructions
The HI-97702 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. The 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.
HI-97702 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. The compact design fits comfortable 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.
Advanced LED optical system
LEDs have a much higher luminous efficiency, providing more light while using less power. They also produce little heat which could otherwise affect electronic stability.
CAL CheckTM
Validate the performance of the instrument at any time and apply a user calibration using CAL Check cuvettes made with NIST traceable standards.
The CAL Check screen guides the user step-by-step through the validation process and user calibration.
Auto logging
GLP
Review of the last calibration date.
On-screen tutorial mode with animations
The built in tutorial mode guides users step-by-step through the measurement process.
Waterproof and floating IP67 case
Auto-shut off
Automatic shut off after 15 minutes of inactivity and 30 minutes before a read measurement.
Battery status indicator
Indicates the amount of battery life left.
Built-in timer
Display of time remaining before a measurement is taken. Ensures that all readings are taken at the appropriate reaction intervals for the test being performed.
Error messages
Messages on display alerting to problems including no cap, high zero, and standard too low.
Units of measurement
Appropriate unit of measure is displayed along with reading.
About Copper
Due to its malleability, thermal and electrical conductivity, and corrosion resistance, copper is used in a variety of industrial and technological applications. Copper may also be present in natural water and effluents due to widespread use to control biological growths in reservoirs and distribution pipes.
