Product information "HI96704 Hydrazine Portable Photometer"
The HI96704 Hydrazine Photometer combines accuracy and ease of use in an ergonomic, portable design. Using the HI93704-0 ready-made reagents a user can accurately determine the concentration of hydrazine within a 0 to 400 µg/L (ppb) range. The HI96704 offers many advanced features including the exclusive CAL Check™ function used for performance verification and calibration of the meter.
  • CAL Check™ Validation and Calibration
  • Built-in Timer
  • Automatic Shut Off

 

 

 

 

 

Details

The HI96704 portable photometer is for the measurement of hydrazine. Hanna's portable photometers feature an advanced optical system; the combination of a light emitting diode (LED), 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 - Ensures the appropriate reaction time is used for the chemical reaction. At the end of the timer 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

Hydrazine is a liquid chemical substance normally used in high pressure heating plants because of its properties as an oxygen inhibitor, helping to avoid scaling and corrosion in the plant itself. Hydrazine reacts with dissolved oxygen to yield nitrogen and water; this is an advantage over the sulfite treatment because it does not produce any dissolved solids in the boiled water. Hydrazine is also used as an energy source in fuel elements, as a reducing agent for metal recovery, and as an intermediate in the production of insecticides, herbicides, pharmaceuticals, and many other chemical products.

The HI96704 uses an adaptation of the ASTM Manual of Water and Environmental Technology, D1385-88 method to measure hydrazine concentrations of less than 400 µg/L (ppb). When the reagent is added to samples containing hydrazine, 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 hydrazine determination, a narrow band interference filter at 466 nm (blue) allows only blue light to be detected by the silicon photodetector and omits all other visible light emitted from the LED. As the change in color of the reacted sample increases, absorbance of the specific wavelength of light also increases, while transmittance decreases.
