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 experienced supply 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.

Why Choose Seven Star LLC for Hach Portable Turbidimeters
An EPA-compliant turbidimeter only delivers regulation-grade results when it is calibrated against traceable standards and the correct measurement range is selected for your actual water source, since drinking water compliance reporting depends on documented, defensible calibration history rather than a factory default reading. Seven Star LLC works with your water quality and environmental compliance teams to confirm the correct 2100Q configuration and calibration standard supply for your monitoring program before order confirmation, drawing on our trusted Hach suppliership across Oman and the wider GCC. We also support municipal water authorities and industrial water treatment operators across Muscat, Sohar, and Salalah with StablCal calibration standard planning and routine verification scheduling, keeping turbidity compliance data defensible for regulatory submission, and our technical team remains available to advise on sample handling procedures that avoid introducing measurement artifacts from bubbles or particulate settling before a reading is taken, so field crews collect consistently accurate NTU values across every monitoring point in a testing program, whether that is a treatment plant clarifier, a distribution network sampling site, or a raw water intake at the head of a treatment train.

Operators use the portable meters and reagents for spot checks, and the sc analyzers and probes for continuous signals to the control system.Ordering Hach products: what we need
Hach identifies every item by a catalog number, for example LXV416.99.20001 for a sensor or 21055-69 for a reagent pack, and the same reagent may be written with or without the dash. Send that number and the quantity. For analyzers and controllers, add the parameter and range, sample conditions, power supply, outputs and communication option. For sensors, tell us the controller model they will connect to and the cable length. For reagents, name the instrument and method so pack size and range can be confirmed against Hach documentation.Browse Hach products by category: Liquid Analytical Accessories, Liquid Analysis Sensors, Portable Test & Measurement, Liquid Analytical Systems.
