Molybdenum Portable Photometer - HI96730

The HI96730 is no longer available.

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

Both meters use the same reagents.

Description

The HI96730 portable photometer is for the measurement of molybdenum. Hanna’s portable photometers feature an advanced optical system; the combination of a special tungsten lamp, a narrow band interference filter, and silicon photodetector ensure accurate photometric readings every time. The Hanna exclusive CAL Check™ feature utilizes ready-made, NIST traceable standards to verify both meter validation and calibration. The exclusive 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 for performance verification and calibration of the meter using a CAL Check NIST traceable secondary standard.

GLP – Records the date of the last user calibration performed.

Built in timer – Allows the use of a timer to ensure the appropriate 3 minutes and 30 seconds reaction time is used for the chemical reaction. At the end of the timer countdown the meter will automatically take the reading. This feature ensures consistency across multiple users.

Indexing indent on meter – The meter has an indent that allows for a lock and key fit with the cuvette cap. This ensures that the cuvette is indexed consistently (same position) in order to maintain the same path length for accurate results.

Cooling Lamp Indicator – It is necessary to maintain a consistent temperature of the optical components in order to maintain a narrow wavelength band of light. This photometer has a cooling lamp indicator that is displayed for a short period of time before each measurement in order to allow the components to cool and obtain the highest accuracy possible.

Error messages – Messages on display alerting to problems including no cap, over range and under range readings, and light source error.

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 not turned off.

Battery status indicator

The instrument has a battery level indicator to display reaming life as follows:

  • 3 lines for 100 % capacity
  • 2 lines for 66 % capacity
  • 1 line for 33 % capacity
  • Battery icon blinks when the capacity is less than 10 %.

Units of measure – Appropriate unit of measure is displayed along with reading.

optical system

Molybdenum is commonly used in creating many types of high strength and steel alloys. It has the ability to withstand extremely high temperatures without significant expansion or softening and displays a high resistance to corrosion. Wastewater from industries that use molybdenum must be treated to remove high amounts before discharge into the public collection system.

The HI96730 uses an adaptation of the mercaptoacetic acid method to measure molybdenum concentrations of less than 40.0 mg/L (ppm). When the three powder packets of reagents are added in succession to a sample containing molybdenum, the sample will turn a yellow hue; the greater the concentration, the deeper the color. The associated color change is then colorimetrically analyzed according to the Beer-Lambert Law. This principle states that light is absorbed by a complementary color, and the emitted radiation is dependent upon concentration. For molybdenum determination, a narrow band interference filter at 420 nm (indigo) allows only indigo light to be detected by the silicon photodetector and omits all other visible light emitted from the tungsten lamp. As the change in color of the reacted sample increases, absorbance of the specific wavelength of light also increases, while transmittance decreases.
