Overview

The GL-7200 online hardness analyzer is compact in structure and easy to operate. It is a device developed based on the principle of national standard hardness titration method to automatically monitor residual hardness in water quality. Equipped with Greencaire's self-developed color grading mode algorithm, it can automatically eliminate the interference of external light changes, ignore the turbidity and color interference of the original water sample, and the pollution interference caused by long-term measurement of the colorimetric pool. It can automatically and accurately determine the hardness endpoint, ensuring the reliability of real-time data.

Features

Automatically measure the total hardness of water within the corresponding reagent kit range. More efficient than manual measurement and more stable and reliable compared to ion selective electrodes.

Based on the national standard titration methodThe development of hardness determination in GB/T6909-2018 has changed from red to blue as the endpoint.

Built in calibration function, users can calibrate themselves.

It can achieve continuous measurement, interval measurement, and external signal triggered measurement.

3.5-inch color screen display, supporting both Chinese and English languages.

The interface adopts a guided menu design, which can quickly get started and use the device.

A 450mL reagent kit can support 2000-4500 measurements.

It can automatically eliminate external light interference, water sample turbidity and color interference, and colorimetric pool pollution interference caused by long-term analysis, and automatically and accurately determine the hardness endpoint.

After each analysis is completed, automatic flushing will be performed, and the flushing duration can be customized to ensure measurement accuracy and repeatability, reducing on-site maintenance.

2 sets of programmable relay outputs, 1 set of 0/4-20mA outputs.

size300x300x170mm， Easy to hang and install.

About storageOne million pieces of data can be exported to a computer to view historical test data.

Can set and control alarm values or trigger external signals when the alarm value is reached
