Conductivity (EC) and TDS (Total Dissolved Solids) measurement with pocket testers is useful because it provides a quick and easy way to check the purity and mineral concentration of water. Here are the main reasons for using these meters:

  1. water quality & drinking water monitoring
  • Checking the purity of tap and spring water
  • Detection of impurities and dissolved salts
  • Checking the efficiency of water filters or reverse osmosis systems
  1. hydroponics & agriculture
  • Ensuring the correct nutrient concentration for plant growth
  • Monitoring salt and mineral concentrations in fertilizer solutions
  • Avoidance of over-fertilization or nutrient deficiency
  1. aquaristics & fish farming
  • Control of water quality in aquariums and ponds
  • Avoidance of harmful salt concentrations
  • Ensuring a stable mineral balance for fish



  1. pool & spa water care
  • Checking the salt content in saltwater pools
  • Checking the chemical balance for clear water
  • Supplement to pH and redox measurement
  1. industry & laboratory applications
  • Measurement of conductivity in chemical solutions
  • Monitoring of production processes in the food & pharmaceutical industry
  • Quality control of ultrapure water in laboratories and electronics production
  1. wastewater & environmental monitoring

  • Monitoring industrial wastewater for dissolved substances
  • Detection of pollution in rivers, lakes or sewage treatment plants
  • Checking the salt concentration in soil water

Why pocket testers?

  • Compact & mobile - Ideal for measurements on the go
  • Easy to use - No complicated calibration required
  • Immediate results - Direct display of conductivity or TDS value
  • Cost-effective - Significantly cheaper than large laboratory measuring devices
