GLT500A steel ruler water level meter is a new type of patented product .The anti-polarization excitation circuit and the corrosion-resistant electrode can effectively prevent the electrode from rusting and maintain the long-term use of the same sensitivity.

Composition:

The instrument consists of a sensor probe, a host, and a 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:

1. Quick response circuit design, high detect speed, high sensitivity

2. Adapt to various environmental and regional water quality

3. Low power consumption, battery-powered use two years at once

4. The cable has a ruler scale to measure the water level directly

Specifications:

 
Use methods:

Before to use , loose the screws in the back of the wire spool . only allow free rotation of the wire spool, press thepower button ( power indicator light ) , the water level probe into the tube , holding ruler cable , so probe move down slowly when exposed to the probe contacts the surface,it will emits a continuous beeping sound from the buzzer , then read out the result. 

If there is a larger noise when measuring environment is bad, you can switch to a peak indication , as long as the selector switch on the instrument panel, it can be released to the voltage block , measurement method as above, the measurement range is the same.
