Water Quality Meters

Water Quality Meters determine water quality by measuring various parameters such as pH, temperature, conductivity, salinity, and temperature. They also measure the presence of fluoride, ammonia, nitrate, sodium, and more. Devices vary from simple pH meters to advanced multi-parameter systems.
 
Water quality meters come in a variety of styles and sizes to meet a range of needs. They are used in numerous applications, including drinking water, waste water, seawater, food and beverage, pool and spa, agriculture, and pharmaceuticals.
 
Water Quality Meter Applications
  • Take control of monitoring regulatory compliance
  • Troubleshoot corrosion in building water/waste water systems
  • Measure conductivity, TDS, salt concentration of a liquid, pH, ORP and DO content
  • Measure oxygen content of a volume of air
  • Field checks of water-based solutions
Key Features of Water Quality Meters to Consider
  • Dual display
  • Wireless communication
  • USB connectivity
  • 3 point calibration ensures the best linearity and accuracy
  • Stores 99 readings manually and 20M readings via 2G SD card
  • Built-in PC interface
  • Selectable conductivity to TDS conversion factor
This video demonstrates ExStik Conductivity Meters. They are multi-parameter devices that eliminate the need to carry numerous devices. These models are just one example of the many types of water quality meters available.
