Overview

The only required maintenance is an occasional, simple cleaning of the sensor flow chamber. (System diagnostics provide automatic alert to clean flow chamber.)

The large backlit display, simple keypad, and logical menu structure make the system easy to use. Menu screens contain up to six text lines to guide the operator through setup, verification of calibration, operation, and test/maintenance functions.

Built-in diagnostic messages alert operator to system malfunctions requiring immediate attention, and to deteriorating conditions that may restrict performance.

A dedicated system alarm relay provides warning if any of these conditions occur.

The pulsed LEDs produce light of a single wavelength, providing highly accurate, reliable performance. Additionally, they last several years, virtually eliminating light source replacement.

A bubble trap built into the Model 8320 sensor flow chamber eliminates stray light and air in the sample to ensure measuring accuracy.

NEMA 4X enclosures protect system components from wet environments, providing years of highly reliable, trouble-free operation.

Verify calibration quickly and easily using GLI’s precision turbid glass cube standard. It is factory-certified to known USEPA approved formazin values, and is 100% reproducible. This extremely stable secondary standard is unaffected by light, heat or aging. (A built-in funnel/ hose assembly is provided for calibration using a traditional primary turbidity standard such as formazin.)

All screens can be selected for display in English, French, German, or Spanish. (Other available languages can be substituted.)

For security, use the T53 analyzer passcode capability to restrict access to configuration settings and verification of calibration to only authorized personnel.
