Portable photometers are for the measurement of ammonia nitrogen in fresh or salt water samples.

Designed to measure the ammonia-nitrogen content in water samples, the Hanna Instruments-96715 is ideal for use in a wide range of applications.

Offering high levels of accuracy as well as being water resistant, portable and easy to use, this meter is hugely popular with operators across the water industry.

A measurement range of 0.00 to 9.99 ppm makes it the optimum solution for quick, efficient and economical ammonia measurement.

Present naturally in surface and wastewaters, ammonia mainly results from the deamination of organic nitrogen-containing compounds and hydrolysis of urea. Ammonia may also be present from water treatment processes that utilise chloramines for disinfection, where ammonia is added to the water to react with chlorine. Ammonia is less likely to appear in groundwater due to absorption to soil particles.

Ideal for

  • Water: fresh and salt water fish tanks and farms, lakes, rivers, portable water, boiler feed water, sewage, industrial and waste water

Key features

      • CAL Check - Allows for performance verification and calibration of the meter using NIST traceable standards

      • GLP – Review of the last calibration date

      • Auto-shut off – Automatic shut off after 10 minutes of non-use when the meter is in measurement mode. Prevents wastage of batteries in the event the meter is accidentally left on

      • 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 reading are taken at the appropriate reaction intervals for the test being performed

      • Error message – Messages on display alerting to problems including no cap, high zero, and standard too low

      • Cooling lamp indicator – To maintain the desirable wavelength to be used for absorbance, it is necessary to ensure components are not overheated from the heat generated by the tungsten lamp. Each photometer is designed to allow a minimal amount of time for components to cool. The cooling lamp indicator is displayed prior to a reading being taken

      • Units of measurement – Appropriate unit of measure is displayed along with reading

Designed for precision

With the Hanna calibration check validation function, users can verify the performance of the meter quickly and easily at any time. Using Hanna NIST traceable standards, it takes just a few moments to check the accuracy of the instrument and to recalibrate as and when necessary.

All new instruments are factory calibrated at source and the electronic and optical design of the Hanna photometers minimises the need for frequent calibration. The Hanna calibration check further minimises the frequency with which instruments need to be returned to the calibration laboratory for full servicing.
