So, switch to these instruments and identify the convenience in them whenever you engage in measuring tasks.
o Measuring Tape/ Tailer’s Measuring Tape.
This type of measuring instrument is widely used in construction sites, tailor shops very often with carpenters and tailors. These are simple linear measuring tools that can measure lengthy structures and have a range of 3-10 m. These also can be used as a height measuring tool and precision is the same as general rulers. Normally two units are included on either side of the tape and are portable. Most tapes come with a handy switch that can lock the tape to a point where you can easily measure the length. Once you release the switch and it will retract back inside the case. Tailer’s measuring tape is normally fabricated with a soft textile material that easily measures the human body. This is a unique feature of these tapes as they are fabricated to easy handling to the specific purpose of measurements. So thorough understanding of these will give you an idea of what to choose out of instruments in the market.

Not only that it included both two units (mm & inch) indicated at two edges. This handy rubber cover design will be easy to use and much durable than other general use tapes.
This is the perfect measuring tape for sewing purposes. Apart from the normal tape design and the build material, the tape is fabricated by considering the ergonomics. Easy in wrapping the tape after measurement and included 30m length.
o Vernier Caliper.
All the measuring instruments we have discussed above are suitable for accurate measurement of a product above 1mm. If the product is fabricated by considering the accuracy of 1mm to 0.01 mm, or measuring the distances around 1mm distance of a product, the vernier caliper is the perfect measuring instrument you must have in your instrument luggage. There are some calipers with the least count of 0.001 but recommended distance for a perfect accurate result of a caliper is 0.01 mm to 100mm.
The vernier caliper works with a vernier scale and a normal scale aligned each other to make fine measurements of a product. Once the product is measured by the main scale, vernier scale is used to find the rest of the distance that cannot measure from the main scale by the above line alignment method.
Vernier caliper is fabricated including some parts/jaws to ease in measuring some small-scale measurements. The upper jaws are used to measure the inner measurement of an object, while the lower jaws are used for measure the outer measurement. A depth rod is present in the later part to measure the depth of the product. These are mainly used for industrial purposes where the measurement of curve, cylindrical bodies and, accurate measurement of metallic parts.
Like in the measuring tape, this caliper also includes a lock screw and thumb screw to keep the scale on to the required distance of the product to measure the length. Some instruments have been upgraded with digital dials which improve the accuracy of the measurement by reducing the human reading error. Not only that there are different types of vernier calipers that are fabricated to provide convenience in measuring different kinds of industrial measurements. Examples of such calipers are Vernier height gauge, Vernier gear tooth caliper, Flat and knife edge caliper, etc. These are mainly used in the aerospace industry, scientific research labs, and machinery and production sites.
Here are some products in the market which can be recommended for your daily activities.
The above product is a standard professional vernier caliper which has a least count 0.02mm and a stainless-steel case. Make sure each Vernier caliper is calibrated before you starting measuring any product.
The above product is equipped with a digital meter, avoiding human reading error when measuring. It also heat-treated and hardened each part that will increase the durability of the product. Perfect for professional usage in aerospace and engineering sites.
- Micrometer gauge.
The micrometer is similar to the vernier caliper which is often used in engineering sites. It has the least count of 0.001 mm which is more accurate than the instruments discussed above. This works on the principle of screw and nut. The screw is attached to a concentric cylindrical part and if the screw is turned through a nut by one revolution the axial movement is equal to the pitch of the thread (distance between two threads) of a screw. Thus, the reading from the micrometer is highly accurate than the vernier caliper. If you need to measure a distance or diameter of a small part to an accuracy of 0.001 mm, Micrometer is the best choice for you.
Here are some of the best micrometers in the market which can be recommended for measuring 0 -25 mm distance.

If you are working around an engineering site, searching for high accuracy measuring instrument with a highly durable rate, this is the perfect match for you.
- Pressure gauge.
The pressure gauges are used to measure water and air pressure on a product and are more often used for measure the air pressure in tires in automobile and aerospace industries. The air pressure is mostly measure by analog pressure gauges rather than digital ones. The reason is that the pressure measurement is not to be more accurate than the linear measurement to the exact decimal place. But it is good to have a digital reading with you if you can afford it.
The above pressure gauge has a range of 0-200 psi, which can use it for industrial use. It is an analog instrument fabricated with steel and chrome front bezel. Recommended for daily industrial use.
Thermometers are used to measure the temperature on the material surface especially on metallic and are helpful in laboratory tests environments and industrial sites where temperature measuring is needed. The most common types of thermometers are J, K -type thermometers. They are used to measure temperature changes up to -150 to 1000 °C. General use thermometers are portable, work with less power and, are powered with batteries. Each type of thermometer is calibrated to give readings within the given specified ranges. Before you purchase a thermometer, you should check which type of thermometers are used in your industry.
Here is the typical K type thermometer that can use for general temperature measuring instances. It has a temperature measuring range of -50 to 500°C and the probe is about 1.5 m lengths which is perfect for surface temperature measurement. This does not have a battery attached, so need to plug it into power source to use it. Can be recommended for a general temperature measuring instrument.
The above discussed tips on measuring instruments are general professional use and are recommended by comparing their physical properties and accuracy of measurement. This can be varied with the industrial regulations and standards. So, it is the best practice for you to check all these instruments conform to the industrial standards and requirements. Always use each instrument as per the instructions on its manual and choose the best quality, durable product for your industrial use.
