Portable Photometer

Advanced Waterproof Portable Photometers

These portable photometers are designed with an innovative optical system that offers superior performance in accuracy, repeatability, and the amount of time that it takes to do a measurement.

These waterproof meters are 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 making operation of the meter very intuitive.

Improved Optical System

LED accuracy, efficiency, and consistency

  • LED that generates little heat
  • 8 nm narrow band interference filter, accurate to ±1 nm for 25% increase in light efficiency
  • Reference detector that modulates the voltage to LED for consistent light output
  • A concave focusing lens that reduces errors from imperfections in the cuvette

High efficiency light source

LED light sources offer superior performance compared to tungsten lamps. 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. LEDs are available in a wide array of wave-lengths, whereas tungsten lamps have poor blue/violet light output.

High quality filters

Improved optical filters ensure greater wavelength accuracy and allow a brighter, stronger signal to be received. The end result is higher measurement stability and less wavelength error.

Stable light source

The internal reference system of these photometers compensates for any drifts due to power fluctuations or ambient temperature changes. With a stable source of light the readings are fast and reliable between your blank (zero) measurement and sample measurement.

Greater light yield

A focusing lens collects all of the light that exits the cuvette, reducing errors from imperfections and scratches that may be present in the glass. The use of the convex lens reduces the need for indexing cuvettes.

General Features

Waterproof casing

The casing offers IP67 waterproof protection and floats.

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 Check™ functionality

Hanna’s exclusive CAL Check feature allows for performance verification and calibration of the meter using NIST traceable standards. Our CAL Check standard vials are developed to simulate a specific absorbance value at each wavelength to verify the accuracy of subsequent readings. The CAL Check screen guides the user step-by-step 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

Allowing time for the reagents to react is primarily important 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 fits 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, virtual keys, a battery status indicator, and error messages. Users will find 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.

Tutorial mode

Tutorial mode provides step-by-step instructions to guide a first time user to preforming a measurement correctly.

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-off protection

These meters use three AA batteries that allow for about 800 measurements to be taken. The auto-off feature automatically shuts off the meter after 15 minutes of inactivity in order conserve battery life.

Battery status indicator

Indicates the amount of battery life left.
