The phreatimeters are used for monitoring the level of groundwater in open tube piezometers, Casagrande and wells.
The tip mounted on the lower end of the cable, as soon as it comes into contact with water, emits an acoustic signal and turns on a led: the level reading is read directly on the graduated cable (centimeter or millimeter).
• Level measurements in Casagrande piezometers, open tube and wells;
• Level measurements in canals, lakes and reservoirs;
• Measurement of groundwater level in landslides, tunnels, excavations or dams;
• Water temperature measurements.
• Acoustic signaller (with buzzer) and visual (via LED) for reaching the water level;
• On and off switch;
• Adjustment of tip sensitivity;
• Probe diameter 12 mm;
• Power supply with 9 Volt battery;
• Cable reel in plastic material equipped with brake and tip holder.
Novatest phreatimeters can be supplied with a centimetrated round cable or with a millimeter flat cable.
The temperature sensor can also be integrated on the probe tip.
A version with integrated display is available for reading the temperature and a device for signaling the reaching of the bottom of the well.
