This is the instruction manual of HI 93700 Ammonia Low Range ISM
The HI 93700 is a colorimeter designed to measure ammonia nitrogen (NH3-N) content in water, wastewater, and seawater within a range of 0.00 to 3.00 mg/L. The instrument utilizes an exclusive positive-locking system for cuvet placement and features an auto-shut-off function that activates after 10 minutes of non-use. It operates using a light-emitting diode light source at 470 nm and a silicon photocell detector, adhering to the ASTM D1426-92 Nessler method.
