I.Features

1. Multiple Functions

1) Transmitter: three connection modes: inductive connection, direct connection and clamp connection; suitable for different occasions.

2) The receiver functions: detecting the position,path, depth and tube current of underground pipes and cables.

3) Left and right positioning arrows indicate the target pipeline position fast and accurately; front and rear arrows and dB value indicates the point and size of the coating damage.

4) Backlight suitable for urgent use in the nighttime.

5) Optional GPS geolocation with the automatic mapping of the pipelines.

6) Optional professional data analysis software with the automatic detection report.

7) Unique feature of HZ-4000AE: locating the breakdown points (pipeline breakdowns refer to the coating damaged points while electric cable breakdowns refer to the outer layer damages.); detecting the insulation damages of underground pipeline and cable.

8) Measuring the current of the pipeline and cable applied by the transmitter.

9) Multimeter function: measure the output voltage, line voltage, line current, impedance and power; Test the cable continuity and insulation quality before and after cable fault finding.

10) External induction clamp: suitable for testing the cable when they cannot be directly applied to the signal of the place.

2. High Location Accuracy

A variety of measurement modes for pipeline positioning (valley mode, peak mode, broad peak mode, peak arrow mode), can verify each other to ensure the accuracy of pipeline positioning.

1) Maximum value method: peak mode, broad peak mode and peak arrow mode are available to determine the horizontal component or horizontal gradient changes, according to its maximum position to locate;

2) Minimum value method: use the valley mode by measuring the vertical component changes according to its minimum position to locate. 

3. Measuring the depth

A variety of methods can be used to verify each other.

1) double-level coil direct reading method;

2) single-level coil 80% method, 50% method;

3) 45 degrees method

4. Strong anti-interference ability

1) Many Observation Parameters: can measure horizontal component , vertical component and horizontal gradient.

2) Large transmission power: the transmitter output power reaches 10W and it could be continuously adjustable.

3) Multiple Working Frequency:

Transmitter frequency: 128Hz, 512Hz, 1KHz, 2KHz, 8KHz, 33KHz, 65KHz, 83KHz.

Receiver frequency: radio, 50Hz, 100Hz, 128Hz, 512Hz, 1KHz, 2KHz, 8KHz, 33KHz, 65KHz, 83KHz.

According to the target pipeline features (material, structure, depth, length, etc.) and the environment to select the appropriate operating frequency.

5. Easy Operation

1) Intuitive: use the graphical display to get the sustained and real-time display of various parameters in the detection process and signal strength.

2) Automatic: in the depth measurement, automatic change to the two-level antenna mode and automatic adjustment of the receiver sensitivity so that the measurement signal achieves the best result. The mode returns to the original one after the depth measurement.

6. Long continuous working time with the low cost

        Both the transmitter and the receiver are equipped with a large capacity lithium battery pack. A fully recharge can last a whole working day outdoors. The recharging function has greatly reduced the detection costs.

7.AC and DC

       Under normal circumstances, if the battery is sufficient, please use the instrument with built-in battery pack power supply. If the battery power is low, and the detection task is not completed, you can use the power adapter to continue the detection without having to recharge the battery.
