Benchtop pH/ISE/EC Dual Channel Meter (HI5522)



HI5522 is a benchtop pH/ORP/ISE and EC/TDS/Salinity/Resistivity meter with a two-channel meter that allows for simultaneous measure of pH, ORP, or ISE on one channel and EC, TDS, Salinity, or Resistivity on the other. 


  • pH range : -2.00 to 20.00
  • pH accuracy : ±0.01
  • EC range : 0.000 μS/cm to 1000.0 mS/cm
  • EC accuracy : ±1% of reading (±0.01 μS/cm)
  • Temperature range : -20.0 to 120°C
  • Temperature accuracy : ±0.2°C


  • Measure pH, electrical conductivity (EC), Total Dissolved Solids (TDS), resistivity, and salinity of water or solution
  • With Ion-Selective Electrode (ISE), the concentration of specific ions  in a solution can be measured.
