The water level indicator consists of a flat, two cores, heavy duty cable calibrated in metres and centimetres on one side.
Water level depth indicator, battery powered (3 x 1.5 V, included and easily replaceable), for use in boreholes to a maximum depth of 200 metres.
A stainless-steel probe is securely fastened to the free end of the cable and the cable with probe is attached to a cable winding reel. Measurements are taken by slowly lowering the cable with probe down the borehole until the probe comes in contact with the water. On contact with the water, the unit emits a high frequency audible signal, and the user can then take a depth reading from the calibrated cable.
The unit is also equipped with an optical (light) signal that switches on upon contact of the probe with water.

The bench is trolley-mounted and has a front panel on which the control devices and all the instruments needed for the tests are located. The system includes two water coolers to cool the air generated by the compressor, complete with thermo-resistances for measuring the temperature of the air and water at the input and output. The Variable Speed Two Stage Compressor Study Unit With Digital Torque Indicator makes it possible to study the major characteristics of a twin-cylinder air compressor with two-stage compression.
