Ion-selective electrode analysis technology has developed rapidly in the past decade and has been widely used in industries such as chemical engineering, metallurgy, soil analysis, clinical diagnosis, environmental protection, and water quality analysis. HC-803 automatic ion analyzer is used with various electrodes (fluorine, nitrate, water hardness, potassium, sodium, chlorine, calcium, pH). It not only measures the potential of the electrode, but also displays, prints, and data communication. Ion concentration (molar concentration, mass concentration, etc.).
The HC-803 Fully Automatic Ion Analyzer is an automatic ion analysis instrument that uses an ion-selective electrode method to perform analysis using a microprocessor. It provides online analysis and data sharing with a computer. The instrument can quickly and accurately measure various ion activities in the solution, and then calculate the fluorine, nitrate, water hardness, potassium, sodium, chlorine, calcium and pH ion content in the solution according to the Nernst equation . The instrument has manual and online monitoring modes, and the online monitoring mode has the characteristics of simple operation and real-time monitoring.

Application areas: drinking water, surface water, industrial production water and sewage.2.1 Site requirements
1. The platform on which the instrument is installed should be stable to avoid instrument vibration.
2. The instrument should be protected from direct sunlight and moisture.
3. Maintain a normal ventilation environment without coverings.
4. Make sure the surrounding environment is clean and free of dust.
5. There should be some free space around the instrument. The installation position of the instrument should not affect the operation of the disconnect device.
6. The instrument must use a plug with a ground wire. When using an external power supply, it must be determined that the ground wire is good.
7. Keep the instrument away from electrical equipment that may cause electromagnetic interference, such as motors, X-ray equipment, etc.; keep away from explosive gases.
2.2 Unpacking After receiving the instrument, check the packing list for any missing parts. If you find any damage or missing parts, please contact the dealer or the company. After the inspection is correct, place the instrument on the platform.
1. Take out the reagent bottle and arrange it according to the standard A liquid, standard B liquid, cleaning liquid and W waste liquid.
2. Unscrew the bottle cap of the standard A liquid, the standard B liquid, and the cleaning liquid bottle, replace the cap with the hole, and insert the standard A liquid, the standard B liquid, and the cleaning liquid suction pipe through the center hole of the bottle cap, and insert into the reagent bottle.
3. Unscrew the empty bottle cap marked with W waste and insert the waste drain into the empty bottle.
Â
Note: During the process of installing the solution or changing the solution later, the user should pay special attention to prevent the standard solution from being cross-contaminated!
1. Arrange the electrode order (as shown in Figure 2, from left to right, F → NO 3 → pH → Ref), with rubber gaskets in between, and put the pin and tighten the nuts at both ends. Make sure the electrode lines are clear.
2. Place the electrode on the mount.
3. Insert the lead plugs into the appropriate socket holes.
4. Connect the nozzles at both ends of the whole set of electrodes to the connecting tube.
1. Open the printer's paper-feed switch and place the roll on the paper shaft and push it into the normal position in the direction of the paper guide.
2. Turn the printer feed shaft gear clockwise until the paper is exposed to a certain length. Adjust the paper to the middle of the printer and press the printer paper feed switch.
1. The power supply voltage is 220 volts.
2. Check that the power switch is in the off position “0â€.
3. Connect the instrument and the power outlet with a power cable.
