The 2100Q optical system is based on the world's classic 2100P portable turbidity meter optical system. It uses Hach's patented ratio measurement. The dual-detector optical system can compensate for the sample's chromaticity, light fluctuations, and stray light. For most samples, even under harsh field conditions, laboratory-level measurement performance can still be achieved.

For fast-sedimenting samples, accurate measurements
Hach's 2100Q portable turbidity meter uses an innovative fast-sedimenting turbidity measurement mode. For fast-sedimenting samples that are difficult to measure, 2100Q can provide you with accurate and reproducible measurement results. Based on a series of automatic readings, a special algorithm can calculate the turbidity value without unnecessary measurements and estimates.

Features and advantages

●  Single standard solution calibration, reducing calibration and operation time
●  Display operation guidance to ensure accurate operation
● RST mode is used to quickly set up samples for accurate turbidity measurement
●User-friendly interface, pre-programmed with 23 optional languages
●Extinction cap control - eliminates ambient light interference
●Flexible component selection to meet user power, connection and data storage components

Accurate measurement for fast settling samples
Hach's 2100Q portable turbidity meter uses an innovative fast settling turbidity measurement mode. For fast settling samples that are difficult to measure, 2100Q can provide you with accurate and reproducible measurement results. Based on a series of automatic readings, a special algorithm can calculate the turbidity value without unnecessary measurements and estimates.

Easy calibration and verification
For every measurement, Hach's 2100Q portable turbidity meter can provide you with reliable measurement results. On-screen prompts for calibration and verification save time and ensure accuracy.

The simple interface allows routine calibration without complicated manuals, and single-point RapidCal calibration provides a simple solution for low-range measurements.

Easy Data Transfer
When using the optional USB+Power module, 2100Q data transfer is very simple and flexible, and no additional software is required.

All data can be transferred to the module and downloaded to a computer using the USB connection device, providing you with useful and complete data.

Two different modules are available, and you can determine the connection and power supply methods according to your own needs.

Convenient data storage function
The instrument can automatically store up to 500 sets of measurement values, which is convenient for users to access and backup.

The stored information includes: date and time, operator number, reading mode, sample number, number of samples, unit, calibration time, calibration status, error message and results.

Two models are available to meet your needs
2100Q Turbidimeter - Compliant with USEPA Method 180. 2100Q IS Turbidimeter - Compliant with ISO7027.
