WMP4 Multiparameter Probe
- Manufacturer: Nesa
- Category: Water quality, SENSORS, Multiparameter Probes
The NESA WMP4 is a multiparameter probe developed for monitoring aquifers, rivers, lakes, landfills, wastewater treatment plants, and clear water. The parameters that can be measured include piezometric level, temperature, conductivity, and pH, using four independent electrodes, each calibrated separately and managed by dedicated electronics.
pH 0–14, level 0–20 m, temperature -5–+60 °C and conductivity 0–6000 µS (0–60000 µS auto-ranging). RS485 interface (IS485/USB module), 10.8–16 Vdc power supply and standard 30 m cable with barometric compensation.
