PQWT supports international projects worldwide. These are content and product-selection priorities—not claims of a local office or exclusive distributor in each country.
Zimbabwe · South Africa · Nigeria · Ghana · Zambia · Ethiopia · Kenya
Prioritize GT, TC, S and M groundwater instruments, then choose the stated range from local geology, nearby boreholes, survey area and practical drilling capacity.
Chile · Peru · Mexico
Review PQ125C, PQ125E and L50 for pipe-leak work, plus GT and TC instruments for groundwater projects. Spanish project details improve model and accessory selection.
Spain · France · Bulgaria
Use detailed specifications, method comparisons, documented limitations, customer cases and downloadable procedures before requesting the final configuration and Datasheet.
Saudi Arabia and regional pipeline projects
Prioritize L-series and PQ125-series leak detectors, then qualify pipe material, diameter, pressure, depth, distance, surface and network conditions before a professional project proposal.
What is PQWT?
PQWT develops and supplies instruments for groundwater exploration, pipeline water leak detection, CCTV pipe inspection, borehole imaging and well water-level measurement. pqwtofficial.com is the official product-information, technical-guidance and international sales-support website used here for model comparison and project enquiries.
Which PQWT product family should I choose?
Use a groundwater detector to screen subsurface geological anomalies before drilling; a water leak detector to locate pressurized pipe-leak signals; a utility locator to trace buried metallic pipes or cables; a CCTV pipeline robot to inspect the inside of accessible pipes; a borehole camera to inspect wells; and a water-level meter to measure static or pumping water level. These instruments solve different problems and are not interchangeable.
Which PQWT GT groundwater detector fits a 150 m, 300 m, 500 m or deeper project?
Review GT150A for stated survey ranges up to 150 m, GT300A for up to 300 m, GT500A for up to 500 m and GT1500A for deep-range professional projects up to a stated 1,500 m. Select from realistic geology, nearby well records, survey area, drilling capacity and interpretation support—not only the largest number in the model name.
Can a PQWT groundwater detector guarantee water, yield or drinking-water quality?
No. A surface geophysical survey detects electrical or natural-field responses that may be consistent with water-bearing structures; it does not directly prove water, sustainable yield, salinity or potability. Use local geology, nearby borehole records, repeat and cross-lines, then verify the target with drilling logs, a pumping test and laboratory water analysis.
Which PQWT-125 model should I choose for pipe leak detection?
PQ125A focuses on concealed indoor pipes, PQ125B on outdoor buried pipes, PQ125C combines indoor and outdoor sensors, PQ125D adds a broader four-sensor configuration, and PQ125E adds tracer-gas capability. The final choice depends on pipe material, diameter, burial or concealment depth, route length, operating pressure, surface and background noise.
Can acoustic detectors find leaks in PVC, PPR, PE or HDPE pipes?
Sometimes, but plastic transmits leak sound less efficiently than metal. Acoustic results improve with adequate pressure, a known route, short sensor spacing, accessible fittings and low background noise. For weak-signal or low-pressure plastic systems, pressure testing and tracer gas may provide stronger confirmation than listening alone.
What is the PQWT-L50 used for?
PQWT-L50 is intended for acoustic screening and pinpointing of concealed pressurized water-pipe leaks, especially in indoor floor and wall work. Build a quiet baseline, compare repeatable points along the mapped route and verify the suspected position before opening the surface. It does not replace pressure testing or repair confirmation.
How do I choose a PQWT 325-series CCTV pipeline robot?
Start with the measured internal pipe diameter, access-opening size, inspection distance, bends, offsets, steps, standing water, silt, required camera view, wheel size, cable reel and report format. Nominal pipe diameter alone is not enough because deposits, liners and deformation can reduce the crawler's real clearance.
What are the published PQWT-PQ325E specifications?
The published PQ325E configuration is a six-wheel-drive CCTV crawler for DN250 and larger sewer, drainage and industrial pipes, with adjustable front and fixed rear 5 MP cameras, IP68 crawler protection, interchangeable wheel sizes, electronic distance measurement and tethered inspection up to 100 m. Confirm the current crawler, wheel, reel, controller, software and accessory package in the quotation.
What information should I send for an accurate PQWT quotation?
Send the country and destination, application, preferred model or required range, quantity and the site conditions that affect configuration. For groundwater projects include target depth, geology and nearby wells; for leak projects include pipe material, diameter, pressure, depth, route length and surface; for pipe robots include internal diameter, access, distance, bends, water and silt.
How can an international customer pay for PQWT equipment?
Company bank transfer by T/T or SWIFT is the normal method for many B2B orders. Eligible confirmed orders may also use a credit or debit card or PayPal. First confirm the equipment, shipping, buyer details and Proforma Invoice; then use only the company bank instructions or order-specific payment link supplied for that confirmed order. Never send card details through the website enquiry form.
Does PQWT provide warranty, training and international shipping?
The website states a standard two-year warranty together with remote operating guidance and technical support. International shipping is arranged according to the destination and confirmed order. The current quotation and Proforma Invoice remain the final reference for included accessories, training, warranty terms, shipping method, Incoterms, duties and taxes.

How these answers are maintained
Answers are based on the product pages, technical guides, customer project requirements and current order process published on this official website. We distinguish stated equipment ranges from guaranteed outcomes, identify verification steps and use the current quotation as the final commercial reference when configurations can vary.
