Hanna Ammonia HR Checker® HC - HI733

Hanna HI733 Ammonia High Range Checker HC is a digital colorimeter providing fast, accurate ammonia determination from 0 to 99.9 ppm in laboratory, field, and industrial environments. This compact instrument bridges the gap between simple chemical test kits and expensive lab-grade photometers, using a fixed wavelength LED at 470 nm and a silicon photo detector for improved precision.

• Measures ammonia with a range of 0.0 to 99.9 ppm and 0.1 ppm resolution, ideal for environmental and water quality monitoring.
• Accuracy is rated at ±1.0 ppm ±5% of reading, suitable for high confidence routine analysis.
• Utilizes the ASTM Manual of Water and Environmental Technology D1426-92 Nessler Method, producing a yellow coloration proportional to ammonia concentration.
• Features a simple one-button operation, built-in timer for consistency, and automatic shut-off after ten minutes to conserve battery power.
• Pocket-sized for true portability, with overall dimensions of 81.5 mm x 61 mm x 37.5 mm and weighs only 64 grams, making it easy to use on-site or in the lab.
• Operates reliably in diverse conditions between 0–50°C and relative humidity up to 95% (non-condensing).
• Powered by a single 1.5V AAA battery for maximum convenience in the field.
• Built to last, with a highly durable enclosure supporting repeated industrial and water lab use.

This ammonia checker is perfect for water treatment facilities, aquaculture, research laboratories, environmental monitoring, and quality assurance in manufacturing.
