Hanna HI718 Iodine Checker HC colorimeter

Hanna HI718 Iodine Checker HC colorimeter

The Hanna HI718 Iodine Checker HC colorimeter is a compact and reliable digital handheld colorimeter designed to measure iodine concentrations in water with ease and accuracy. It serves as an efficient alternative to chemical test kits, bridging the gap between basic visual color comparison methods and complex laboratory instrumentation. Ideal for users who demand precision and simplicity, this device is suited for water treatment, food processing, laboratory research, and general water quality monitoring.

By utilizing the DPD method adapted from the Standard Methods for the Examination of Water and Wastewater (18th edition), the HI718 ensures consistent and trustworthy results by detecting the color change resulting from iodine reacting with the reagent.

Features

• Wide Detection Range (0.0 to 12.5 ppm)
  Allows accurate monitoring of iodine in various water systems, from low to elevated concentrations.

• Precise Digital Readout
  Offers a resolution of 0.1 ppm with ±0.1 ppm ±5% accuracy, removing the subjectivity of color interpretation found in test kits.

• Palm-Sized and Portable
  Lightweight and compact design makes it convenient for field use and mobile applications.

• Simple One-Button Operation
  Delivers quick, repeatable measurements in just four steps, perfect for both professionals and non-technical users.

• Reliable Optical System
