The Apera Instruments EC8500 Portable pH/Conductivity/TDS/Salinity Meter Kit is designed for lab-grade conductivity measurement in the field with various intelligent functions and a rugged structure.

Instrument Features

  • GLP Data management (1000 groups of data storage), USB data output.
  • Ideal for use in harsh environments — IP57 Waterproof rating, silicone socket protector and grip cover protect the instrument from general impact.
  • The large backlit LCD displays conductivity/TDS/salinity and temperature along with icons of stable readings and finished calibrations.
  • The foldable stand allows use as a benchtop meter.

Conductivity Features

  • The BPB 2301T-S Conductivity/Temperature Electrode adopts a brush-resistant platinum black coated sensor, which ensures a lab-grade measuring accuracy (±1% F.S ±1 digit) in an ultra-wide range (0 to 200,000 µS/cm / 200 mS/cm).
  • Single-tap switch among conductivity, TDS, and salinity.
  • Quick and easy 1-3 point conductivity calibration with functions of calibration reminder and last calibration check.
  • Built-in self-diagnosis ensures conductivity calibration will be performed correctly and guides you on how to fix common problems.
  • TDS conversion factor can be set from 0.40 to 1.00.
