The SEBA-Electric Contact Meter type KLL is a portable, reliable instrument for measuring water level and total depth in boreholes. To take a measurement the sensor is lowered to the water level. When it reaches water, a light is illuminated. On request, an additional acoustic signal can be installed. The water depth is shown on the cable in metres and centimetres. If the total depth is also desired, an additional
ground sensor (see accessories) is available. When this sensor touches the bottom, the light switches off. The standard sensor diamter is 14mm abd for small diameter boreholes, there is a sensor with 10 mm diameter (not suitable for ground-sensor and sensor-cap).Models are also available to also measure temperature (KLL-T).
