Hanna Instruments HI-97733 Portable Ammonia Photometer, High Range

The Hanna HI-97733 photometer measures high-range ammonia in water. It has a step-by-step tutorial mode for users of all experiences, a backlit dot matrix LED, an optical system, a reference detector, and narrow-band interference filters.

The virtual keys make the operation very intuitive with method selection, reviewing GLP data, recalling the last 50 measurements, and customisation options. The LCD is 71 mm, and the meter runs on three AA batteries. A kit option includes extras and a carry case to store and transport your gear.

Key Features

• High Range Ammonia levels - 0 to 100.00 mg/L (as NH₄⁺N)
• No warm up time before taking a measurement
• Tutorial mode for step-by-step instructions
• Displays results in multiple chemical forms
• Stable Light Source: Internal reference system ensures consistent readings by compensating for power and temperature fluctuations.
• High-Efficiency LED: LEDs provide more light with less power and minimal heat, improving measurement stability.
• Precision Optical Filters: Enhanced filters improve wavelength accuracy and signal strength for reliable readings.
• Maximized Light Yield: A convex focusing lens eliminates errors from cuvette imperfections, reducing the need for indexing.
• CAL Check Verification: Validate and calibrate performance with NIST traceable standard vials.
• Flexible Reagent Options: Compatible with both powder packets and cost-effective liquid reagents.
• Built-in Reaction Timer: Ensures consistency by displaying countdowns for accurate test timing.
• Large Cuvette Compatibility: Supports 25 mm glass cuvettes for precise low-absorbance measurements.
• Intuitive Display: Backlit graphic LCD with virtual keys, battery indicator, and on-screen help.
• Auto-Off Feature: Extends battery life by shutting off after 15 minutes of inactivity.
• Ammonia Measurement: Uses the Nessler method to measure ammonia in water (0 – 100.00 mg/L), displaying results as ammonia or ammonium.
• Ammonia in Water: Exists as ammonium (NH₄⁺) at pH <8, converting to toxic ammonia (NH₃) at higher pH, impacting aquatic life.
• Drinking Water Application: Commonly added at <0.4 mg/L to enhance chlorine disinfection.
• Advanced Optical System: Features an 8 nm narrowband filter, reference detector, and concave lens for superior accuracy.
