Contact Meter Type KLL

The SEBA-Electric Contact Meter type KLL is a portable, reliable instrument for measuring the water level and total depth in boreholes, wells, reservoirs etc.
For the measurement the bob is lowered to the water level. When touching the level, a sensor effects the illumination of a signal lamp. On request, an additional acoustic signal will be released by a buzzer. The depth is shown on the cable in metres and centimetres. If the measurement of water level and total depth is desired, an additional ground sensor (see accessories) is adaptable. When the sensor is touching the bottom, the signal lamp is switched off. In case of very small diameter tubes, instrumentes with a probe of 10 mm dia. (not suitable for ground-sensor and sensor-cap) are available.

Principle of function

When the probe is touching the water-level there is a conductive connection between the tip of the probe and the sensor-body. Thereby a circuit of the lamp and the buzzer will be closed.

SEBA-Electric Contact Meter Type KLL-T

The SEBA-KLL-T has been developed for accurate measurements of water level and temperature in groundwater observation tubes and wells.
Offering quick indication of the temperature, the instrument is suitable for the determination of temperature profiles.

Principle of function KLL-T

Water level measurement:
When the probe is touching the water-level there is a conductive connection between the tip of the probe and the sensor-body. Thereby a circuit of the lamp and the buzzer will be closed.

                               This electric contact meter is used for a qualitative measurement of conductivity.
                               An exact measurement is provided by the SEBA electric contact meter type KLL-Q.

Contact-Meter Type KLL-Mini

With the KLL-Mini a full contact-meter in pocket-format has been developed. In quality regards it's equivalent to the existing KLL-family. Generally it is equipped with optical and acoustic signal, which enables the exact measurement of the water level. The two 1,5V batteries are sufficient for approx. 250 measurements.
For convenient transport and safe storage a protection bag is available, made of textile with zip, carrying strap and belt loop.

Depth Indicator Type TLG

The SEBA-Depth Indicator Type TLG has been developed as a portable unit for rapide and accurate observation of bore hole water levels. It also can be used for measurements in the open sea or for measurements of the cross section of a lake. Operated manually by holding above the bore hole it provides a clear, instantaneous indication on a five figure counter calibrated in metres and centimetres and is rapidly rewound.

Advantages:
-mech. measuring system
-rapide and accurate measurements
-digital indication of the measuring result
-handy and portable
-light in weight and compact design
