Hanna HI97707 Nitrite Low Range Portable Photometer – 0.000 to 0.600 mg/L

The Hanna HI97707 is a highly precise, waterproof portable photometer designed to measure Low Range Nitrite (NO_2^-) in water. Utilizing an adaptation of the EPA Diazotization method, it accurately measures nitrite concentrations from 0.000 to 0.600 mg/L (ppm) as NO_2-N. Featuring CAL Check™ performance validation and an IP67 casing, it is the standard diagnostic instrument for municipal water treatment plants and sensitive aquaculture environments.

Ensure absolute public safety and marine health with the Hanna HI97707 Nitrite Low Range Photometer. In municipal drinking water, elevated nitrite levels are highly toxic, causing "blue baby syndrome" by restricting oxygen in the blood. Similarly, in commercial aquaculture and high-end aquariums across Pakistan, nitrite is lethal to fish even at microscopic levels. Municipal WASA authorities and fisheries must monitor these levels with flawless, legally verifiable precision.

The HI97707 is explicitly designed for this critical safety task. Operating on the globally recognized EPA Diazotization Method, it measures nitrite concentrations in the ultra-sensitive 0.000 to 0.600 mg/L (ppm) range with a staggering 0.001 mg/L resolution. The meter features a Reference Detector that constantly modulates the voltage to the internal LED, ensuring that the light output never drifts due to battery drain. Fully IP67 Waterproof, it is built to survive daily field testing at remote municipal tube-wells and fish hatcheries.

Key Features:

• EPA Compliance: Utilizes the exact chemical methodology required by international Environmental Protection Agencies for isolating toxic nitrite.
• Ultra-Low Sensitivity: The 0.001 mg/L resolution provides the absolute earliest warning of biological filter failure in commercial aquaculture.
• CAL Check™ Verification: Instantly proves the meter is functioning flawlessly using Hanna's certified, NIST-traceable optical standards.
• Positive-Locking Cuvette: Ensures the glass vial locks into the exact same position every time, preventing optical alignment errors.

Frequently Asked Questions (FAQs):

Q: What is the price of the Hanna HI97707 in Pakistan?

A: Check Kamadi.pk for competitive B2B rates. We support commercial municipal teams and fisheries with officially certified Hanna diagnostic tools.

Q: Does this measure Nitrogen or Nitrite?

A: The reading is displayed as Nitrite-Nitrogen (NO_2-N). However, the photometer allows you to easily change the chemical form on the display to show absolute Nitrite (NO_2^-) or Sodium Nitrite (NaNO_2) without doing manual math.

Q: How many readings does it store?

A: The meter automatically logs the last 50 measurements, allowing inspectors to record data across multiple city tube-wells before returning to the office.
