Chemical Oxygen Demand Portable Photometer HI-97106

Description

Hanna Chemical Oxygen Demand Portable Photometer HI-97106

The instrument is a compact and versatile low, medium, high, and ultra-high range photometer designed to accurately determine chemical oxygen demand. Suitable for field or bench measurements in the water and wastewater industries, plus other industries wanting to measure COD.

The HI-97106 is a waterproof portable photometer with an advanced optical system that uses a Light Emitting Diode and a narrow band interference filter for accurate, repeatable readings.

The optical system is sealed from outside dust, dirt, and water. The meter uses an exclusive positive-locking system to ensure that the vials are placed into the holder in the same position every time.

With the CAL Check™ functionality, users are able to validate instrument performance at any time. Hanna Instrument’s CAL Check cuvettes are certified against NIST-traceable reference instruments.

The built-in tutorial mode guides users step-by-step through the measurement process. The tutorial mode includes all steps required for sample preparation, the required reagents, and quantities.

More about the photometer
CAL Check™ validation – Validate instrument performance at any time using CAL Check™ cuvettes made with NIST traceable standards.

Removable vial adapter – The vial adapter can be removed to accommodate HI-97106-11 CAL Check™ cuvettes for validation.

On-Screen guides – Step-by-step on-screen guidance.

Auto-data logging – Data autolog helps users keep track of all measurements. Data is automatically saved every time a measurement is made. The data log can hold 200 individual measurements. When the data log is full, the meter will rewrite the oldest data point.

Waterproof and floating, IP67 meter design

HI-97106 On-Screen display and operating keys
Method and Parameter – The chosen parameter and method used is displayed on-screen along with the reading.

You can also see the battery status indicator and auto-shut off – The auto-off feature automatically shuts off the meter after 15 minutes of inactivity in order conserve battery life.

Virtual keys – Menu available at the touch of a button

Dedicated help – A dedicated help key provides information relating to the current meter operation, and can be used at any stage in the setup or measurement process to show contextual help.

About COD
Hanna equipment can be used in the laboratory or for on-site testing. Examples include: power plant operations, chemical manufacture, commercial laundries, pulp and paper mills, agriculture, environmental studies and general education, plus the water companies in the UK for wastewater and drinking water, and the food industry.

Chemical Oxygen Demand is a measurement of the biologically available and inert organic matter that is susceptible to oxidation by a strong oxidising agent.

The Hanna COD method is based on the well-established closed dichromate-reflux colorimetric method. The colorimetric measurement of COD is faster and easier to perform than the titrimetric analysis.

The advantages of using this method includes certifiable results as well as high accuracy.

COD is used to measure pollutants. It is normally measured in both municipal and industrial wastewater treatment plants and gives an indication of the efficiency of the treatment process. COD is measured on both influent and effluent water.
