Product Overview

• HI96753 is no longer available.

• Below is a link to a new meter that has been upgraded with many advanced features, including an improved optical system, dot-matrix LCD, which provides a graphical tutorial mode to help users complete the measurement process, and is waterproof, including the cuvette assembly.

• Both meters use the same reagents.

• The HI96753 portable photometer is used to measure chloride. Hanna's portable photometers use an advanced optical system; the combination of a light-emitting diode (LED), a narrow-band interference filter, and a silicon photodetector ensures accurate photometric readings every time. Hanna's exclusive CAL Check™ feature uses ready-made NIST-traceable standards to verify meter validation and calibration. A dedicated cuvette locking system ensures that the cuvette is inserted into the measurement cell in the same position every time to maintain a consistent path length.

• Features at a glance

• CAL Check™ - allows performance verification and calibration of the meter using CAL Check NIST-traceable secondary standards.

• GLP - records the date the last user calibration was performed.

• Built-in timer - allows the use of a timer to ensure the chemical reaction uses the appropriate 3 minute 30 second reaction time. When the timer countdown ends, the meter will automatically take a reading. This feature ensures consistency between multiple users.

• Indexing detent on the meter - the meter has a detent that allows a lock and key to engage with the cuvette cap. This ensures that the cuvette is consistently indexed (same position) so that the same path length is maintained for accurate results.

• Cooling lamp indicator - in order to maintain narrow-band light, it is necessary to keep the temperature of the optical components consistent. This photometer has a cooling lamp indicator that is displayed for a short period before each measurement so that the components can cool and the highest possible accuracy can be obtained.

• Error messages - displayed messages warn of problems, including no cap, over-range and under-range readings, and light source errors.

• Auto shut-off - when the meter is in measurement mode, it automatically shuts off after 10 minutes of non-use. Prevents wasting battery if the meter is accidentally left on.

• Battery status indicator

• The instrument has a battery level indicator to show remaining battery life, as follows:

• 3 bars, 100% capacity

• 2 bars, 66% capacity

• 1 bar, 33% capacity

• When the battery is below 10%, the battery icon flashes.

• Measurement unit - the appropriate measurement unit is displayed together with the reading.

• Chloride, as one of the major inorganic anions in water and wastewater, is frequently measured in various industries. Due to its corrosiveness, chloride levels in boiler systems and cooling towers are monitored to prevent damage to metal components. Chlorine is not currently known to be toxic to humans, but due to its negative effect on taste, chlorine in drinking water is monitored for aesthetic purposes. However, chloride can be toxic to plants. Chloride can be monitored in agricultural applications in certain regions of the world where salinity levels are known to be naturally high.

• The HI96753 uses the mercuric thiocyanate (II) method to measure chloride concentrations below 20.0 mg/L (ppm). When both mercuric thiocyanate (II) and an iron-based reagent are added to a sample containing chloride, the sample will turn orange; the higher the concentration, the deeper the color. The associated color change is then analyzed colorimetrically according to the Beer-Lambert law. This principle states that light is absorbed by the complementary color, and the emitted radiation depends on the concentration. For chloride determination, a 466 nm (blue) narrow-band interference filter allows only blue light to be detected by the silicon photodetector, while ignoring all other visible light emitted by the LED. As the color change of the reacted sample increases, the absorbance of light at a specific wavelength also increases, while transmittance decreases.
