Richiedi informazioni

  For many titrations, a potentiometric determination of the equivalence point is simply not possible. However, manually performing complexometric titrations can be inaccurate due to ambiguous color changes and when using non-aqueous or semi-opaque liquids, such as lubricating oils. In these cases, the use of a photometric probe for the optical determination of an endpoint during volumetric analysis is preferred. Hanna Instruments introduces HI900604 photometric electrode for when a color change is still the best solution.

Info Ordine

The HI900604 photometric electrode has a blue LED with a wavelength of 470 nm as a light source. This wavelength of light is useful for determining a yellow endpoint when using indicators such as bromophenol blue during a volumetric titration. The HI900604 can be used for a variety of applications, including:

Carboxyl end groups in polymers according to ASTM D7409.

LED at 470 nm

HI900604 uses a LED that emits light at 470 nm (blue color). This high quality LED will provide long term use since it takes thousands of hours for the LED intensity to dim naturally.

Reflective Measurement

The HI900604 contains a glass flow through cell, which the sample fills. The LED shines light at 470 nm through the sample, which is reflected back by a platinum mirror sealed in the glass tip of the probe. The fixed path length of the reflective measurement allows for high color sensitivity in a compact design.

Automatic Temperature Compensation

All readings are compensated for the changes in temperature of the sample from 0 to 75^oC (32 to 167^oF) to provide for accurate and repeatable measurements.

Glass-Body Probe

HI900604 probe has a glass-body that offers excellent chemical resistance against organic solvents. These solvents can be found in samples and can attack different forms of plastics.

Steel Shielding

The electronics of the probe are located in a steel shielding, which is covered by the glass-body. The steel sheilding of the probe also blocks out ambient light and protects against electronic interference.

12 mm Diameter Probe Body

HI900604 has a probe diameter of 12 mm (1/2"), which is the standard size for most pH/ORP electrodes. The 12 mm probe will fit in most electrode holders.

BNC Connector

HI900604 has a BNC connector for connecting a pH/mV input of a meter. The mV range for the probe is from 10 to 1100 mV.

PS/2 Mini-DIN Connector

A PS/2 connector is used for supply power to the probe. The HI931and HI932 potentiometric titration systems have a ps/2 power output for the probe to be connected to. The HI900932 is a PS/2 Y-splitter that is also available and allows for multiple probes to use one power source.

LED Calibration Trimmer

Although the LED provides a very long life, it does slowly dim over time. A trimmer located in the head of the probe can be used to adjust the output intensity. This allows the probe to be recalibrated, ensuring accurate measurements. The probe is placed in DI or distilled water and the trimmer adjusted until 1000 mV (100% transmittance) is displayed.
