Hach 2100Q Portable Turbidimeter (EPA), 0-1000 NTU

Overview

The Hach 2100Q Portable Turbidimeter is a field-ready water quality instrument built for accurate, EPA-compliant turbidity measurement across municipal water treatment, industrial process water, and environmental monitoring applications. Engineered to meet EPA Method 180.1 standards and measuring in Nephelometric Turbidity Units (NTU) across a 0–1000 NTU range, the 2100Q gives field operators laboratory-grade turbidity data without requiring a benchtop instrument or return trip to a fixed lab.

Seven Star LLC supplies the Hach 2100Q as an authorized partner of Hach, supporting water utilities, environmental laboratories, and industrial water treatment operators across Muscat, Sohar, Salalah, and the wider Sultanate of Oman. Genuine Hach turbidimeters, calibration standards, and accessories are available through Seven Star LLC for water quality monitoring programs throughout the GCC.

Measurement and Operating Principle

The 2100Q measures turbidity using nephelometric light scatter detection: a light source passes through the sample, and suspended particles scatter the light onto detectors positioned to capture the scattered signal, which is proportional to sample turbidity. The instrument’s two-detector optical system simultaneously compensates for sample color, light source fluctuation, and stray light interference, allowing the 2100Q to deliver laboratory-grade accuracy across a wide range of sample types, including samples with color or difficult optical characteristics that would introduce error into simpler single-detector designs.

Compliance with EPA Method 180.1 ensures the 2100Q’s readings are directly usable for regulatory reporting on drinking water and wastewater turbidity, a critical compliance parameter for water utilities operating under U.S. EPA or similarly structured international regulatory frameworks. The intuitive calibration and verification workflow streamlines routine instrument checks, helping operators maintain measurement confidence between full recalibrations.

Engineering Design of the Hach 2100Q

The 2100Q is built into a rugged, ergonomic handheld enclosure designed for one-handed field operation, with a backlit display showing turbidity value, units, and instrument status at a glance even in variable outdoor lighting. Sample cells load into a dedicated compartment that shields the optical path from ambient light, ensuring consistent, repeatable readings whether operating in a bright field environment or a dimly lit plant.

Onboard calibration and verification routines guide operators through standard checks using certified turbidity standards, helping maintain traceable measurement accuracy for regulatory and quality assurance programs. The instrument’s rugged construction and intuitive interface make it well suited to daily use by field technicians and plant operators who need reliable turbidity data without extensive instrument training.
