Measurement and analysis
Every signal.A clearer view.
A noise level tells part of the story. Time waveforms and frequency analysis help examine changes, identify dominant components and compare a measured response.
T2000 combines signal acquisition with analysis software and excitation output for laboratory and engineering tests.
Explore the CapabilitiesFrequency spectra
Examine dominant frequencies in noise or vibration measurements.
Octave analysis
Review acoustic energy across octave and fractional-octave bands.
Excitation output
Use sine, noise or sweep signals in a defined test arrangement.
Industrial applications
Built around
the work you do.
Electrical inspection, process maintenance and product testing require different measurements. Start with the operating environment.
Power & utilities
Investigate suspected partial discharge around substations, switchgear, cable terminations and distribution equipment.
Field inspection / Electrical condition checks

Energy & process
Screen pipework, valves and equipment for acoustic leak sources in power generation, steel and process facilities.
Gas leaks / Compressed air / Steam systems
See Field Applications 
Manufacturing & R&D
Examine product noise, structural vibration and acoustic response. Investigate seal leakage under defined test conditions.

Follow the sound.
Find the cause.
Acoustic imaging located suspected floating discharge at an incoming bushing. Disassembly confirmed poor internal contact and burn damage; the affected component was replaced.
Inspection value: a localized source for targeted maintenance.

Investigate the leak.
From a distance.
The partner case covers positive- and negative-pressure leak investigations around an electrostatic precipitator, combustion chamber and gas pipework.
Inspection value: acoustic localization across multiple plant areas.
Case-specific distance, not a guaranteed detection range. Leak rate and energy savings were not reported.

Trace the source.
Refine the seal.
Door, door-handle, body-edge and rear-body views document acoustic inspection during a negative-pressure test. Suspected leak locations guided follow-up checks.
Four documented views, not four quantified leaks. The source does not report L/min, test pressure or cost savings.
The figures above describe documented site conditions and inspection records, not measured savings or guaranteed performance. Leak-flow and financial outcomes require validated project data.

Project-specific monitoring
A longer view.Of your equipment.
Portable inspection helps locate a source at a particular moment. Continuous monitoring uses installed sensors and a configured acquisition system to follow equipment over time.
The supplied airport-power reference combines sensor deployment at cable wells and switchgear with a monitoring platform for trends and alerts.

Continuous monitoring is a separately scoped solution. It is not included automatically with either portable instrument.
Qidoo industrial acoustics
Independent brand.
Focused expertise.
Qidoo manufactures and supplies acoustic inspection and signal analysis equipment under its own brand. We share production resources with Chenqiao and are an authorized sales partner.
Our focus is the measurement task: what you need to locate, what you need to record and how you will use the results.

Planning your equipment
A clearer brief.
A better equipment match.
The right configuration begins with a few specific questions, before a model or accessory list is selected.
Describe the task
What asset are you inspecting? Are you locating a sound source, measuring vibration, testing a seal or tracking a condition?
Define the setup
Share the working environment, sensor types, measurement points and any required software functions or data outputs.
Confirm the scope
Agree the instrument configuration, supplied accessories, documentation and delivery requirements in the quotation.
Before you choose
A few useful
answers.
Have more technical questions?
Talk to our team about your application, sensors and measurement requirements.
Do I need both T1000 and T2000?
No. T1000 is for visual sound-source localization. T2000 is for multi-channel signal acquisition, analysis and excitation tests. Select one or both according to the measurements your project requires.
Does an acoustic image confirm a fault?
An acoustic image helps locate a sound source. It does not by itself establish the root cause. Interpretation depends on operating conditions, and suspected faults or leaks may require follow-up inspection or other tests.
Which sensors can I use with T2000?
The supplied configuration supports ICP or voltage inputs. Microphone, accelerometer or other sensor compatibility should be checked against its output, power requirements, sensitivity and required measurement range.
Are the laptop, sensors and software modules included?
Example photographs illustrate a test arrangement, not a fixed package. The quotation should specify the analyzer, sensors, cables, accessories, software functions and language requirements.
What should I send with an inquiry?
A short description of the task, equipment photos, operating conditions, required channels and any existing sensor details. For a monitoring project, include the measurement locations, communications requirements and intended alarm or reporting workflow.
