Multiple COD Measurement Ranges

One of the important advantages of the Hanna HI97106 COD Meter is its ability to measure COD across different concentration ranges. The instrument supports Low Range, Medium Range, High Range, and Ultra High Range COD methods.

The Low Range measures from 0 to 150 mg/L, while the Medium Range covers 0 to 1500 mg/L. For samples with higher COD concentrations, the High Range extends measurement up to 15000 mg/L. The instrument also supports an Ultra High Range from 0.0 to 60.0 g/L, providing flexibility for different water and wastewater samples.

Advanced Optical System

The HI97106 features an advanced optical system based on an LED light source, silicon photocell detector, and narrow-band interference filter. Hanna states that the optical system is sealed from outside dust, dirt, and water.

The instrument also uses a positive-locking vial system, helping ensure that vials are positioned consistently in the measurement chamber. This design supports repeatable measurement conditions during routine COD testing.

CAL Check™ Validation

The Hanna HI97106 COD Photometer includes CAL Check™ functionality, which allows users to verify the performance of the instrument using certified CAL Check cuvettes.

This feature provides a convenient way to check instrument performance and helps laboratories maintain confidence in their measurement system. Hanna’s CAL Check standards are certified against NIST-traceable reference instruments.

Built-in Tutorial Mode

The HI97106 includes an integrated Tutorial Mode that provides step-by-step guidance during the measurement process. The tutorial can guide users through sample preparation, required reagents, and reagent quantities.

This makes the instrument easier to operate for routine laboratory COD analysis while helping users follow the appropriate testing procedure.

Waterproof IP67 Design

The Hanna HI97106 COD Meter (COD) Photometer features an IP67 waterproof floating case, making it suitable for demanding laboratory and field environments. Its compact dimensions of 142.5 × 102.5 × 50.5 mm and weight of approximately 380 g with batteries make it convenient for portable testing.

Data Logging and Measurement Management

The instrument provides automatic data logging for up to 200 readings, allowing users to store measurement results for later reference. It also features a backlit 128 × 64 pixel LCD, providing a clear interface for measurement and instrument settings.

The automatic shut-off function turns the instrument off after 15 minutes of inactivity, helping conserve battery power.
