Description
The HI97733 is built with a durable IP67-rated body that withstands knocks, drops, spills, and even floats if accidentally dropped into water. Its sealed optical system prevents dust, dirt, and water from affecting internal components, ensuring long-term reliability. The photometer uses a positive-locking cuvette positioning system to guarantee consistent placement for accurate readings. The advanced optical system includes a 420 nm LED light source, an 8 nm narrowband interference filter (±1 nm accuracy), a silicon photocell detector, and a focusing lens that minimizes errors from scratched or imperfect cuvettes.
Designed for professional ease-of-use, the HI97733 features a backlit 128 × 64 pixel LCD with intuitive virtual keys, tutorial mode, and a dedicated help button. The built-in reaction timer ensures consistent testing among multiple users, while automatic logging of the last 50 measurements and GLP data review provide traceability. The CAL Check™ functionality allows performance verification and recalibration using NIST traceable standards. Powered by 3 AA batteries (over 800 tests per set), with auto-off protection, this compact photometer is ideal for field and benchtop ammonia testing in the 0.0 to 100.0 mg/L range.
