Turbidity Meter

Ratio Measurement Mode

These meters measure turbidity using the ratio method with a 90° and 180° light detector for accurate measurements.

 

Multiple reading modes

Normal, continuous, or signal averaging easurement reading modes available.

 

ISO Compliant

Both meters exceed the requirements of ISO 7027 method for turbidity measurements by use of an infrared LED light source.

 

Calibration

HI98713 and HI987134 feature a powerful calibration function that compensates for variation in light intensity. A two, three, or four-point turbidity calibration can be performed by using the supplied (<0.1, 15, 100 and 750 FNU) standards. Calibration points can be modified if user-prepared standards are used.

 

Fast Tracker™

For advanced field applications, the HI98713 is equipped with Fast Tracker™ Tag Identification System (T.I.S.) that makes data collecting and management simpler than ever. Fast Tracker™ allows users to record the time and location of a specific measurement or series of measurements using iButton® tags near sampling points for quick and easy readings. Each iButton® tag contains a computer chip with a unique identication code encased in stainless steel.

 

Backlit Graphic LCD Display

A graphic LCD display provides an easy to understand, user-friendly interface. All messages are in plain text making them easy to read.

 

AMCO AEPA-1 Primary Turbidity Standard

The AMCO AEPA-1 supplied standards are recognized as a primary standard by the USEPA. These non-toxic standards are made of styrene divinylbenzene polymer spheres that are uniform in size and density. The
standards are reusable and stable with a long shelf life.

 

GLP Data

Features complete GLP (Good Laboratory Practice) functions that allow traceability of the calibration conditions. Data includes calibration points, date, and time.

 

Data Logging

Up to 200 measurements can be stored in the internal memory and recalled at any time.

Data Transfer

Logged data can be downloaded to a Windows® compatible PC using the USB or RS232 port and the HI92000 software.
