Product description
Technical indicators

One, digital titrator

The on-site water quality parameter test components provided by Hach Company use different methods and chemical reagents to determine water samples.

The product is simple, easy to operate, and high in measurement accuracy. The user can choose the appropriate on-site water quality test component according to the different measured parameters.

The test components provided by Hach Company include counting titrators, digital titrators, test papers, colorimetric columns, colorimetric discs and other products.

Using the digital titrator provided by Hach Company and the matching titrant, more than 20 parameters can be measured. Compared with the traditional glass tube buret device, the digital burette

The volume of the titrant consumed can be counted to the nearest microliter, and the end point of the titration is easy to grasp. The digital titrator can be operated in the factory and the field work site, a breakthrough

The glass tube titration device can only be operated in the laboratory under the environmental conditions.

The digital titrant adopts the method of replacing the burette and titrant to achieve the purpose of measuring multiple parameters. The matching burette and titrant are provided in a disposable package

For experimental personnel, the burette is made of anti-chemical corrosion materials, and the titrant is safe and reliable during use.

 

 

The experimenter used the burette with anti-chemical corrosion materials, and the titrant was safe and reliable during use.

3. Remove the cap of the reagent cartridge and install the drainage tube. If it is a handheld titration, use a 180-degree drainage tube. If you use a titration stand, choose a 90-degree drainage tube. Set the titrator to zero after removing the air bubbles.

4. Intrude the head of the drainage tube below the liquid surface of the sample, turn the handle to start the titration to the end of the titration.

5. Convert the concentration value of the measured parameter according to the reading of the digital titrator.

2. Multi-parameter field test components

The multi-parameter field test group provides multi-parameter water quality analysis suitable for multiple industries and various outdoor environments. Multi-parameter display

The field test group includes all the reagents and accessories required for field test, which can meet the requirements of customers on-site and use it out of the box. test

The main methods include colorimetric discs, colorimetric columns, counting titrators, digital titrators, DR300, etc.
