The Equipment for Quality Control Services

equipment quality control

In the age of globalized trade, no one wants to run into defects when receiving their imports from China. You need a trustworthy team to oversee the quality of your imported products and address customer concerns before they impact your bottom line.

Read on to learn more about Jonble and how equipment quality control services can support your business model and earn your customers’ confidence.

Tools Used For Precise Quality Control Measurements

When following inspection protocols for quality control, a skillful team must have a variety of tools to test and measure every aspect of a product before and after it’s completed. Depending on what specifications you need to measure, you may need to use some tools more than others.

We take initiative by using an array of tools for taking precision measurements and performing necessary inspections. Here are examples of the many tools used for quality control services.

Temperature Measurements

There are many thermometers used for quality inspection of products. For example, when testing the temperature resistance of products, you can determine when its functionality starts to dwindle.

Measuring Density and Other Liquid Properties

During testing, quality control teams use hydrometers to measure the density of liquids based upon buoyancy and determine their specific gravity. In testing, workers can measure the solutions in batteries or the quality of antifreeze for engine cooling. They can also use refractometers to check the refractive index of most industrial liquids.

Quality control services may also use centrifuges to separate liquids with different densities. When separating solvents from samples, workers can use Kjeldahl-Digestion and Distillation Apparatuses.

Taking Precise External Measurements

When performing inspections, QC specialists may take external measurements of the product. One of the tools designed to fulfill this duty is the outside caliper. It’s adjustable to a maximum reach of 10 inches. This is an ideal tool if you need precise measurements of an object as thick as a pipe.

Vernier calipers also measure product exteriors. It also takes measurements of a product’s interior and depth. Rigid steel rulers and tape measures can also perform this task.

Pathogen and Trace Element Detection, Extraction, and Elimination

During inspections, QC services use tools to reduce the number of microbes to keep you and your products safe. Our team uses API strips to identify known bacteria. Staff also use autoclaves to kill harmful bacteria, viruses, and pathogens on your products with different temperature and pressure levels.

VIDAS/miniVIDAS Pathogen Detection Kits are staple tools used for food and water analysis to ensure health and safety.

When extracting microbes, QC companies use stomacher mixers to turn them into a solution and use rotary evaporators to remove solvents through evaporation. Kjeldahl Digestion and Distillation Apparatuses can help determine organic nitrogen and protein contents in chemical substances that might be present in certain products.

Measuring Thickness

Depending on what products you’re interested in manufacturing, you’ll need to create specifications for the thickness of its material. Facilities use ultrasonic thickness gauges to inspect the thickness of metals, plastics, and glass to the nearest millimeter. It’s useful for monitoring thickness that may wear away.

Making Adjustments

QC services utilize precision straight leaf feeler gages to measure spark plugs, distributor points, and valve clearances. They’re also used to measure the spaces between most parts of your product. Once they make the measurements, workers make sure that the parts don’t overlap each other.

Measuring Pressure

Some tools for measuring pressure during quality control inspections include dial indicators. They measure the accuracy of a workpiece, from scales to engines. For example, companies can use tools to measure the breaking strength of pencils or chalk to determine its overall quality.

Measuring the Size of Drill Bits

When constructing your products, we’ll need to know the precise specifications for what screws and bolts you’d like to install. A drill bit gauge measures the size of fractional drill bits. These measurements reach from 1/16 in. to ½ in. by 64ths. QC employees compare the sizes to match your preferences to ensure that the products stay secure once manufactured.

Measuring pH

Gauges measure the pH specifications for your products. A gauge measures the difference in electrical potential between a pH electrode and a reference electrode to deduce the acidity of liquid solutions. Depending on what levels you desire, the QC team uses these tools to meet your specifications.

Measuring Electrical Energy

When working on electrical imports, QC teams use various tools to measure energy within electric units. Voltmeters measure the electrical potential difference between two points in an electric circuit. Wattmeters measure the electric power or energy rate of a product’s electrical circuits.

Pulse generators may also be used for detecting frequency. This tool is crucial for other forms of spectrography.

Depending on your specifications, quality control teams work to ensure that the amount of energy a product uses is sustainable and stable in comparison to its longevity.

Gas Compression

Headspace analyzers measure the oxygen concentration of sealed containers. Data from this tool can be used for detecting, leaks, package permeation, and container strength.

Reciprocating compressors compress intake gas into compressed gases at high pressure. Examples of products made using these methods include air conditioning and refrigerators.

Dimension Measurements

Another simple tool used for quality control are gauges. Air gauges measure all types of product dimensions. They can track internal and external dimensions for accurate measurements. Air gauges can also measure a product’s thickness, depth, diameter, and taper.

Bore gauges specifically measure the inside of a product, but can also measure the dimensions of parts, grooves inside of a part, dimensions inside of a part, and degrees of taper. Mechanical bore gauges gave moving components used for taking measurements. Electrical bore gauges use electrical currents to take measurements.

Charting Inspection Results

When companies handle quality control, they use several tools to track progress and data of what manufactured products work and which ones don’t. After making these measurements, they record the results to use as a reference for fixing defects. Some examples of non-machine quality control tools that most companies use include:

  • Histograms (used for developing corrective actions against defects)
  • Check Sheets (used for categorizing defect observations and their frequencies)
  • Pareto Chart (used for measuring the frequency of defects and their impacts)
  • Cause & Effect (used for identifying the leading causes of defects that need reduction or removal)
  • Scatter Diagram (used for measuring which poor performance of dependable variables result from independent variables causing a product’s defects)

Most facilities create quality control charts dedicated to specific product attributes and divert them into many other divisions of charts to measure samples and detect if defects occur at random or at a frequent consistency.

Our experts at Jonble use these techniques to identify product issues and find out their causes and frequencies. We observe factory activity of completed products and see which aspects of them successfully or unsuccessfully meet the consumer’s manufacturing needs. Then, we create resolutions to these problems.


Quality control is a crucial part of solving your import needs, so having a team on your side to handle those duties is essential. There are numerous tools that our team uses to make precise measurements of all components of your projects to reduce defects in your imports. Some of these tools measure your product’s dimensions, while others focus on extracting and identifying pathogens to keep you and your imports safe.

At Jonble, we calculate the frequency of defects and compare them to mandatory manufacturing requirements. Then, we offer services to correct mistakes and reduce defects when finalizing the products for shipment. In short, we do the troubleshooting and problem-solving so you don’t have to.
