Hanna Instruments-83314KIT-HR Chemical Oxygen Demand Starter Kit - High Range

This economical starter kit is designed for those starting out measuring COD, or for those who need a complete new system for a new site and is available at a considerable saving compared to buying the items separately.

Featuring the Hanna Instruments-83314 Multi-parameter Wastewater Photometer

Combines the 20 most commonly measured wastewater parameters with the ability to measure COD.

One meter can be used for both photometric and pH measurements.

Hanna Instruments-83314 is a compact, multi-parameter photometer for measuring key water and wastewater quality parameters.

The meter is one of the most advanced photometers available with an innovative optical design that utilises a reference detector and focusing lens to eliminate errors from changes in the light source and from imperfections in the glass cuvette.

Ten key water and wastewater quality parameters with 20 different methods.

Key features:

• Backlit 128 x 64 Pixel Graphic Liquid Crystal Display


• Built-in Reaction Timer for Photometric Measurements


• Absorbance mode - concentration versus absorbance


• Units of Measurement plus chemical form displayed


• Result conversion at the touch of a button


• Cuvette cover


• pH and temperature measurement with a single probe


• Good Laboratory Practice (GLP) - track calibration information including date, time, buffers used, offset and slope for traceability


• pH CAL Check alerts user to potential problems during the calibration process


• Data Logging - Up to 1000 photometric and pH readings can be stored.


• Logged readings can be quickly and easily transferred to a flash drive or to a PC. Data is exported as a .CSV file for use with spreadsheet programs.


• Battery Status Indicator


• Error Messages


• High efficiency LED light source


• High Quality Narrow Band Interference Filters


• Reference Detector for a Stable Light Source


• Large Cuvette Size


• Focusing Lens for Greater Light Yield

About the Hanna Instruments-839800 High accuracy multi-vial heater reactor block

The Hanna Hanna Instruments-839800 thermo-reactor is an easy to use test tube heater with the capacity to perform up to 25 simultaneous digestions. Complete with a countdown timer, it can be used for timed or infinity testing procedures.

Robust and durable, the main body is machined from a single block of metal. Temperature within the block is controlled using a sophisticated electronic thermostat and can be verified by placing a thermometer in the temperature well provided.

The reactor is equipped with 6 pre-defined and 2 user-defined °C profiles.

• Dedicated temperature profiles for COD and total phosphorus reactions are pre-set to 150°C


• The total nitrogen analysis temperature is pre-set to 105°C


• In adjustable temperature mode (50 to 150°C), the heater can be used for other samples that require different digestion temperatures

Key features

• Heater block temperature is continuously evaluated and displayed on the LCD


• Low temperature alert indicates that temperature is below set value


• High temperature alert warns when temperature rises above the set value


• Reactor has a thermal fuse that prevents overheating by disabling the heater


• Countdown timer shows time remaining until heating element shuts off


• A three hour countdown timer is ideal for timed digestion


• The sound of a 'beep' indicates when the timer has expired and the heating element turns off


• To operate in infinity mode, the timer can be used without the shut-off feature


• Visual power indication


• Green LED indicates power on


• Blinking red LED warns if heater exceeds 50°C


• Yellow LED indicates heating is active


• For optimum safety, the block heater should always be used with a safety shield or other physical barrier placed between samples under test and operator

The Hanna Instruments-93754 Pack of 25 COD Vials

Each box of 25 vials is supplied with a Hanna certificate of quality. The reagents are traceable to NIST SRM® 930.

• Hanna vials contain approximately 3mL of pre-dosed reagent. The operator just needs to add a small quantity of the sample.


• With pre-dosed vials, test preparation time is dramatically reduced. There is no time-consuming reagent preparation procedure or glassware cleaning.


• Hanna COD reagents are safe for operators and the environment. Vials and caps have been designed to avoid accidental reagent spills. Due to the pre-dosed reagents, the amount of chemicals and handling time is minimised.
