Several multi-parameter portable conductivity meters support the measurement of conductivity, pH, TDS, temperature, salinity, and resistivity.
Portable conductivity meters are small in size, easy to carry, and have reinforced and waterproof protection for the case and sensor, which can be used for a variety of outdoor testing.
1 to 5 point calibration, automatic recognition of conductivity standards. Measurement accuracy: 0.5% F.S. These portable conductivity meters are suitable for use in a variety of industries such as experimental research, school education, and aquaculture. Optional electrode constant (K=0.1/1/10), reference temperature (20/25°C), TDS conversion factor, linear and pure water compensation modes.
Automatic temperature compensation, corrects conductivity measurements and converts readings to reference temperature.
Automatic endpoint lock, retains stable readings for easy viewing and recording.
Calibration report, showing calibration points and conductivity cell coefficients.
Automatic power off, saving battery power.
Reset function automatically restores meter to factory default settings.
Expandable memory to store or access up to 500 data sets.
USB interface, easy to transfer data to PC.
Multi-mode power supply ensures smooth application of the meter.
