Field and laboratory water analysis needs readings you can trust without slowing the workflow. The PRO 52x handheld conductivity meters support portable checks of conductivity, temperature, resistivity, salinity and TDS, using a fixed 4-pole graphite/epoxy/PVCU measuring cell with integrated temperature sensor for automatic compensation.
Daily operation stays clear in changing conditions. The backlit dot matrix display shows large values, statistical information or a live chart, while HOLD and MIN/AVG/MAX functions help capture and review measurements. Ingress protection (IP) IP67, IK 04 impact protection, side rubber protection, a foldable stand and a magnet support use in the field or on the bench.
For documented measurements, the PRO 525 variant stores up to 1 million CSV data sets with date and time stamp and reads out via USB-C as a mass storage device.
The instrument uses a fixed cable probe with a 4-pole graphite/epoxy/PVCU conductivity cell and integrated temperature sensor.
Conductivity measurement can use automatic compensation from the integrated sensor, with nLF, Lin, NaCl or off settings.
Measurement screens include large digit view, multi-row view, statistical display with Min/Avg/Max and chart view.
Configurable alarm thresholds can trigger LCD indication, buzzer activation and optical signaling when limits are exceeded.
The device operates with 4 AA batteries and can also be powered via USB-C from a 5 Vdc adapter, PC USB port or suitable power bank.
USB-C supports PC connection; PRO 525 can use COM interface mode or mass storage mode for logged files.
Conductivity adjustment can be performed manually or with selectable standard solutions; the last calibration date is stored.
