Hanna HI726 Nickel HR Checker HC

Hanna HI726 Nickel High Range Checker HC – Handheld Colorimeter for Nickel Measurement

The Hanna HI726 Nickel HR Checker HC is a portable and highly accurate digital colorimeter designed for measuring high concentrations of nickel in solution, with a range up to 7.00 g/L. Built for simplicity and reliability, it bridges the gap between traditional chemical test kits and complex laboratory instruments. This palm-sized device delivers fast, precise results using a user-friendly interface, making it ideal for both field testing and laboratory use.

Utilizing a colorimetric method with a LED light source at 575 nm, the HI726 reacts with nickel in the sample to produce a color change, which is then quantified photometrically. This ensures objective and repeatable readings, eliminating the guesswork of visual color comparison.

Key Features

• High Measurement Range
  Capable of detecting nickel concentrations from 0.00 to 7.00 g/L, making it suitable for industrial and wastewater applications.

• Exceptional Accuracy
  Delivers accurate readings with ±0.10 g/L ±5% of the reading, ensuring compliance and quality assurance.

• LED-Based Photometry
  Uses a 575 nm LED light source and a high-sensitivity silicon photocell for stable, consistent performance.

• Compact and Portable
  Lightweight (64 g) and ergonomically designed, ideal for field professionals and on-site testing routines.

• Simple Operation
  Operates with a single button for measurement and power, reducing user error and improving efficiency.

• Auto-Off Function
  Conserves battery power with automatic shutdown after three minutes of inactivity or ten seconds after a reading.
