Why choose Ensprima's online hardness analyzer from the UK?
Currently on the marketOnline hardnessThere are various types of analyzers, and in terms of measurement principles, there are mainly three mainstream methods: spectrophotometry principle, titration colorimetric method, and ion selective electrode method. How can customers choose a suitable online hardness analyzer? It is generally recommended to consider the accuracy, stability, purchase cost, maintenance volume, and operation and maintenance cost of the online hardness analyzer comprehensively. The following is an overview of measurement principles and performance maintenanceWe hope to conduct relevant instrument analysis to help customers choose online hardness analyzers.

Principle of spectrophotometry
Determine the concentration of calcium and magnesium in the sample using single wavelength colorimetric method. The sample reacts with calcium magnesium indicators and buffering agents, causing the solution to change color. The absorbance is measured at 520nm using a colorimeter, and the absorbance is linearly proportional to the hardness. Due to the indirect measurement, two types of standard samples are required for calibration to determine the offset and slope values

characteristicWide measurement range, high accuracy, automatic cleaning, automatic calibration
disadvantageThe purchase cost of the instrument is relatively hightallThere are up to 5 types of reagents, multiple pipelines, and complex maintenance, requiring regular replacement of reagents (<2 months) and high consumables every year. Easy to be affected by the aging of electronic components, requiring high technical proficiency from maintenance personnel.

Principle of titration colorimetric method (Jensprima online water hardness analyzer from the UK)
Determine the total hardness concentration of calcium and magnesium in the sample by titration colorimetry. The instrument measurement tank automatically quantifies samples, and hardness reagents are added to the measurement tank through a precision metering pump for reagent titration. Each drop is 30 microliters, and the titration is very accurate. The hardness reagent will react with the sample and the solution will change color. An optical sensor is used to detect the intensity of the color and determine the endpoint of the color change. The total hardness concentration can be determined based on the amount of reagent consumed.

Features: Wide measurement range (0.5-534ppm CaCO3), automatic cleaning, automatic calibration, high accuracy (± 5%), high stabilityOnly one reagent is needed, with a validity period of 2 years,1 bottle can be tested up to 10000 timesBasically maintenance free, the purchase cost of the instrument is reasonable. Almost unaffected by the aging of electronic components.

Principle of ion selective electrode method
Measure the hardness concentration in water using a calcium/magnesium ion selective electrode. Due to the selectivity of the electrode towards calcium/magnesium ions, the concentration of calcium and magnesium is directly related to the potential measured by the electrode. Since this method is an indirect measurement, calibration is necessary.

Features: Low instrument purchase cost, fast response speed
Disadvantages: Accuracy and stabilityNot high, high detection limit, easily affected by ions, short electrode lifespan,Unable to automatically clean and calibrate. Not suitable for applications with low concentration hardness.

Product features:

●Fully automatic measurement

Automatically measure the total hardness of water in different ranges based on the selected reagent. This analysis process is more effective than manual measurement and more consistently reliable than other indirect measurement methods such as ion selective electrodes.

●Intelligent and accurate

The national standard measurement method - titration colorimetric method, the instrument has calibration function. The integrated measurement technology and two-stage analysis process can identify external measurement influences (such as contamination of the measurement tank, turbidity of the water sample, and external light) and eliminate these influences during the measurement.

●Multiple measurement modes

-Continuous measurement

-Interval measurement (5-99min)

-External switch signal initiates measurement

●Compactness

The size is only 300x300x200mm, which can be directly hung on the wall or installed on a bracket.

●Minimum maintenance workload

The water and detection device are completely isolated, with a detachable measuring slot that does not require additional tools for maintenance and can be easily executed. It is recommended to replace the spare parts package once a year (including: peristaltic pump head reagent connecting tube, agitator, sealing ring, order number: 50-5000-10)

●Automatic cleaning

Rinsing and Cleaning are automatically performed for each analysis, ensuring measurement accuracy, repeatability, and reducing on-site maintenance.

●Low reagent consumption

The reagent bottle can be easily replaced, and 500ml of reagent can measure 5000-10000 times. The validity period of the reagent is 2 years.

●LCD backlit LCD display

Multi language graphic backlit LCD displays measurement values, remaining reagent levels, alarm values, and relay status.

●0/4-20mA output

●SD card data storage

2G data storage card, can be directly imported into the computer to view historical data and system fault information in Excel format.
