50m 100m 300m Cable Ruler Deep Well Water Level Meter with Sounder

GLT500A steel ruler water level meteris anew type of patented product.The anti-polarization excitation circuit and the corrosion-resistant electrode can effectivelyprevent the electrode from rustingandmaintain the long-term use of the same sensitivity.
Composition:
The instrument consists of asensor probe, a host, anda reel.Easy to use:
√ Slowly slide the sensor probe head down into the water.
√ When the probe head touches the water, an induced potential is generated.
√ After circuit processing, sound and light instructions are issued.√Then read out the height difference data between the surface and the ground from the ruler.Features:
