Question 1

What is your minimum order quantity (MOQ)? Can I order samples?

Accepted Answer

There is no minimum order quantity for our standard products. You can order a single unit for evaluation or purchase in bulk.

Question 2

Are you a manufacturer or a trading company?

Accepted Answer

We are a manufacturer specializing in the research, development, and production of measuring instruments since 2008. We offer a wide range of instruments for industrial testing applications.

Question 3

How do you ensure product quality? Can you provide certificates?

Accepted Answer

Our instruments undergo quality inspections before shipment. Inspection reports and third-party calibration or testing certificates may be available upon request. Please contact us to confirm availability and any additional fees.

Question 4

What is your warranty and after-sales service policy?

Accepted Answer

Our instruments come with a 12-month warranty. We provide technical support and offer paid repair services after the warranty period.

Question 5

What are your payment methods, delivery terms, and lead times?

Accepted Answer

We accept payments in USD and CNY via T/T or Western Union. Our standard delivery terms include EXW and DAP. Lead times depend on product availability and order quantity. Please contact us for details.

Question 6

Do you offer OEM or customized products?

Accepted Answer

Yes, we offer OEM and customization services. Please contact us with your specific requirements to discuss available options.

Question 7

Are import duties and taxes included in the price?

Accepted Answer

Import duties and taxes depend on the destination country's regulations and are generally not included in the product price. We can provide the HS code for reference. Please consult your local customs authority for applicable charges.

Question 8

How do I protect the probe cable?

Accepted Answer

Avoid sharp bends at the connector and do not pull the instrument by the cable. Store the probe coiled loosely in the case, and check the cable screen if the reading becomes noisy, because a broken screen causes unstable values near electrical equipment.

Question 9

Where is the LS221 commonly used?

Accepted Answer

It is used for coated steel structures, pipe racks, welded frames, vehicle bodies and machine parts where the measurement point is awkward to reach. It is common in marine, aerospace, metal fabrication and painting contractors where the operator works above head height or inside a structure.

Question 10

How do I measure inside a steel frame with the LS221?

Accepted Answer

Hold the host where you can read it, guide the small probe into the frame with the cable, and press the probe flat against the surface. Keep the cable away from sharp edges, and take three readings along the member because the coating thickness varies at welds and corners.

Question 11

Can the gauge measure on a curved or hot surface?

Accepted Answer

Curvature down to a stated radius is acceptable, and beyond that a reading should be corrected or the part supported. Very hot surfaces are not suitable for most models because the probe and the electronics have a working temperature limit.

Question 12

Why do I get different values at different points on the same panel?

Accepted Answer

Paint thickness genuinely varies across a panel, especially on curved areas, edges and repaired zones. Measure at least five points, take upper, lower, left, right and centre positions, and use the average. Avoid measuring within a few millimetres of an edge, a weld or a sharp curve, where the geometry distorts the field.

Question 13

What is the LS221 coating thickness gauge?

Accepted Answer

The LS221 is a coating thickness gauge with a separate host and cable probe, measuring non magnetic coatings on ferrous metal and non conductive coatings on non ferrous metal. The detached probe lets the display stay in view while the probe reaches narrow spaces, high positions and the inside of frames.

Question 14

What are the key specifications of the LS221?

Accepted Answer

Dual principle Fe Hall effect and NFe eddy current, range 0 to 5000 um, resolution 0.1 um, 1 um and 0.01 mm, accuracy within +/-(3 percent of reading + 2 um) up to 3000 um, measuring interval 0.5 s, minimum measuring area 25 mm diameter, host 101 x 62 x 28 mm, probe 71 x 26 x 22 mm, and a weight of 114 g with battery.

Question 15

How does the LS221 differ from the LS220H?

Accepted Answer

The electronics and accuracy are the same. The LS221 is the split type: the probe is on a cable, which is better for narrow or raised positions but needs two hands. The LS220H is the integrated type for fast one hand scanning of flat panels.
