Turbidity (EPA)

Turbidity (EPA) and chlorine meter is one of the high precision laboratory equipment used to analyze important variables in drinking water such as chlorine and turbidity. By controlling these two parameters, it reduces the possibility of adverse events that reduce water quality, such as the growth of pathogenic agents, bad taste and smell, and water color change. Untreated water supply from natural sources

The Turbidity (EPA) meter is one of the laboratory equipment used in the water and sewage laboratory.
Designed specifically for measuring water quality, this turbidity meter meets and exceeds the requirements of EPA Method 180.1 for wastewater and Standard Method 2130 B for drinking water. This microprocessor based meter provides highly accurate measurements in the range of 0.00 to 1000 NTU.

The optical system of the meter consists of a tungsten filament lamp and two detectors (scattered and transferred). As the light beam passes through the sample vial, the microprocessor of the meter calculates the NTU value. Two-, three- or four-point calibration (<0.1, 15, 100 and 750 NTU) can be performed using the supplied standards, and full GLP (Good Laboratory Practice) functions allow traceability of calibration conditions.

The built-in Fast Tracker™ functionality allows you to record the time and location of a specific measurement or set of measurements using iButton® tags placed at sampling locations. The meter records up to 200 readings and has a backlit display. Includes five sample cuvettes and caps, calibration cuvette, silicone oil, cleaning wipes, five iButton label holders with labels, battery, AC adapter, instruction manual, and carrying case.
