The Apera Instruments EC850 Portable Conductivity/TDS Meter Kit is designed for lab-grade conductivity measurement in the field with various intelligent functions and a rugged structure.
Instrument Features
- Ideal for use in harsh environments — IP57 Waterproof rating, silicone socket protector and grip cover protect the instrument from general impact.
- The large LCD displays conductivity/TDS 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).
- Quick and easy 1-3 point conductivity calibration
- Built-in self-diagnosis ensures conductivity calibration will be performed correctly and guides you on how to fix common problems.
- Single-tap switch among conductivity and TDS.
- TDS conversion factor can be set from 0.40 to 1.00.
