Features, keys

1. Compact design
   It allows compact installations and does not occupy much space.
2. Can operate in harsh environments
   Can be used in harsh conditions such as high and low temperatures and high pressures.
   
3. Can be made to meet special specifications
   A special sensor can be manufactured to match your tank.
4. Simple re-calibration
   Zero and span adjustment by pressing buttons. Once the desired settings are stored in the housing, there is no need to re-enter them.

Usages, use examples

The conductivity of liquids can be measured in any industry, including research institutes, water processing facilities, semiconductor plants, environmental research, food production, chemicals and pharmaceuticals, and printing.

• Control the density of various agents
• Control the water quality in a boiler
• Control the water quality of factory drain water and water processing facilities
• Quality control, such as the density and mixture ratio of liquids in production processes
• Measure the conductivity of cleaning and plating fluids for surface processing lines
• Measure the distilled water used in semiconductors, food processing, and pharmaceutical production
