VisionPlus EC3840 is an easy to use, IP67 rated portable conductivity meter with TDS, salinity and temperature readouts. Key features include a water-proof / dust-proof body, 4-wire conductivity cell, selectable cell constant and adjustable TDS coefficient.
- Simultaneous display of conductivity, salinity or TDS with temp. measurements
- Selectable cell constants for true wide range readings
- Adjustable TDS coefficient, reference temp. , temp. coefficient for most flexible and accurate TDS readings
- Automatically finds the most suitable display range for your measurements
- Accepts 4-wire conductivity cell
- Uses one conductivity cell for conductivity, salinity and TDS measurements
- IP67 rated body for water-proof (up to 1 meter) and dust-proof operation
- Removable shock-resistant rubber boot
