HZGZ-713A is a set of intelligent underground pipeline detecting system, composing of transmitter and receiver. It can be used to
detect the path of metal pipeline, underground cable, pipe's or cable's general checking and the
depth measuring. The detecting system coperates with some optional fittings, can carry out with uniqueness distinguish, the pipeline's insulation damage or some types of cable faults finding.
Multi-functions
1. Compass and direction display: Intuitively display the pipeline's location and left/right direction.
2. Tracing right/wrong prompt: Current direction measuring, tracing right/wrong prompt, eliminating surround interference(Some frequencies)
3. Depth and current measurement, display the previous curves of signal's strength.
4. Fully digital high precision taking sample treatment: Stable and reliable, very high sensitivity, narrow receiving frequency zone, stong anti-interference, completely suppressing the power frequency and harmonic wave's interference of surround living cable.
5. Living cable detect: High performance transmitting clamp, furthest output signals to cable coupler.
6. Cable/Pipeline distinguish: Soft caliper(optional) convenient to operate, show clear distinguish results; stethoscope(optional) can be used when the caliper isn't convenient to use.
7. Grounding fault find: Booster(optional) can improve the maximum output voltage to be 1000V, adopting A type shelf(optional), locating the pipeline's insulation damage point, no need to adjust to "zero", the arrow indicates the fault direction.
8. Multi-kinds of detecting frequencies: Actively detect or passively detect.
9. The transmitter has various of signal output ways: Direct connecting output, caliper coupling, radiating induction.
10. The transmitter digital function amplifies power output, fully automatic impedance matching, fully automatic protection.
11. Built-in detachable large capacity lithium battery, automatically turns off when the voltage is absent, or no operation for a long time.
12. The housing is stable, portable to carry with.
