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

What is the maximum insulating unit that can be measured?

Accepted Answer

For double glazing the sum of the two glass thicknesses plus 1.5 times the air space must be below 70 mm. For triple glazing the total glass thickness plus 1.5 times the total air space must be below 70 mm. This weighting accounts for the longer optical path through the gas space.

Question 9

How accurate is the measurement and what affects it?

Accepted Answer

Accuracy is about 0.1 mm for the LS201 digital glass thickness gauge on clean, flat, parallel glass. Dirt, a scratched surface, a strong tint, a curved pane or a badly out of parallel unit all reduce accuracy. Clean the surface before measurement and press the instrument flat against the glass.

Question 10

Can it measure glass bottles or curved glass?

Accepted Answer

Glass bottles and curved glass can deflect the laser beam, making the LS200 and LS201 laser glass thickness gauges unsuitable for these applications. For measuring container wall thickness, an ultrasonic thickness gauge is recommended.

Question 11

How do I measure a double glazed unit with the LS201?

Accepted Answer

Place the instrument flat against the indoor face, press the measure key and read the layer list: outer glass, air space, inner glass. If the automatic mode does not identify the structure, switch to manual mode and select the glass type before measuring again.

Question 12

Why does the LS201 sometimes fail to read a Low E unit?

Accepted Answer

A soft low emissivity coating changes the reflection at the coated interface and can weaken one echo. Measure from the uncoated side where possible, clean the glass, and use the manual mode with the correct structure selected, which applies the proper layer model.

Question 13

Where is the LS201 commonly used?

Accepted Answer

It is used for installed curtain wall glass, insulating glass units, laminated glass, doors and windows, and shop fronts. It is the instrument of choice for a facade surveyor or a glazing contractor who must record the glass build up of an existing building.

Question 14

What are the key specifications of the LS201?

Accepted Answer

Glass thickness up to 70 mm and air space up to 45 mm, accuracy within +/-(0.1 mm + 1 percent of the reading), minimum measurement area 5 x 50 mm, LCD display of 240 x 160 pixels, body 130 x 72 x 33 mm, weight 330 g, and 4 AA batteries.

Question 15

What is the difference between the digital and the scale version?

Accepted Answer

The digital version displays the thickness of each glass layer and each air space directly, needs no calculation and offers higher accuracy. The scale version shows the reflection positions on a scale and requires the operator to read and calculate the values, so it is slower and less precise but considerably cheaper.
