Rotary Knob Desktop Turbidity Meter — ZD103

This Rotary Knob Desktop Turbidity Meter is a precision laboratory instrument designed for reliable measurement of suspended particles in liquids. It employs the nephelometric principle, measuring the scattering of light caused by suspended solids, to deliver accurate and repeatable turbidity readings in NTU (Nephelometric Turbidity Units).

Its defining feature is the intuitive rotary knob interface, which provides superior tactile control for effortless menu navigation, calibration, and data review. This user-centric design minimizes errors and streamlines operation compared to devices relying solely on membrane keys.

Key characteristics include a high-resolution optical system for excellent low-range sensitivity, multiple calibration points for wide measurement range, and a large, clear LCD display. For data integrity, models often feature built-in data logging and USB/RS-232 connectivity for direct transfer to a computer or printer.

The meter is essential for water quality testing in environmental and drinking water laboratories, process control in beverage, pharmaceutical, and wastewater treatment industries, and educational applications. It typically complies with major standards like ISO 7027 and EPA Method 180.1.

Combining robust performance with straightforward operation, this turbidity meter is an ideal solution for labs seeking a durable, accurate, and user-friendly instrument for routine water clarity analysis.
