1. Sonde: Stainless steel, inside mounted the water resistance point, when the point touch the surface, the receiving system will be turned on, when the contacts out of the water, the system will automatically turn off.

2.Ruler cable parts: Together with the ruler and wires, with good function of corrosion resistance, Oil resistance, microbes resistance.

3. Receiving system: composed of the sounder and peak indication. When the sonde reach to water, the water completes an electrical circuit powered by a 9v battery, sending a signal back to the reel where a light and clearly audible buzzer are activated. The water level is then determined by taking a reading off the cable at the top of the borehole, casing or tube, and then measuring off to the nearest mark.

4. Reel: composed of wire spool and holder, the receiving system and battery are mounted inside the wire pool. Outside the wire pool, the ruler cable is on it.

Benefits:

• Gives you years of accurate use – High-strength tape reduces stretching, ensuring accurate readings over the lifetime of the meter. Corrosion-resistant probe and protected electronics prevent wear and tear.
