Understanding Measuring Instruments
Everything you need to know about vernier calipers, infrared thermometers, bore gauges and choosing the right instrument.
What is a Vernier Caliper?
A vernier caliper is a precision instrument that measures the internal, external and depth dimensions of an object to an accuracy of 0.02 mm. It has a main scale and a sliding vernier scale that together give the reading. A digital vernier caliper shows the reading directly on an LCD screen for faster, error-free measurement.
What is the Least Count of a Vernier Caliper?
The least count of a standard vernier caliper is 0.02 mm (or 0.001 inch). It is found by dividing the smallest main-scale division by the number of divisions on the vernier scale, and it shows the smallest change the instrument can measure.
What is an Infrared Thermometer?
An infrared thermometer is a device that measures the surface temperature of an object without touching it, by reading the infrared energy it gives off. It is used to check motors, bearings, electrical panels and process surfaces safely, often up to 500°C or more.
Types of Measuring Instrument
Different jobs need different instruments. Dimensional instruments like vernier calipers and micrometers measure length and diameter, electrical instruments like multimeters measure voltage and current, and specialised instruments measure temperature, noise and bore size. The right instrument depends on the parameter, the accuracy needed and the working range.
| Instrument | Measures | Typical Resolution | Best For |
|---|---|---|---|
| Vernier Caliper | Length, depth, ID/OD | 0.02 mm | General dimensional checks |
| Micrometer | Small dimensions | 0.01 mm / 0.001 mm | High-precision measurement |
| Bore Gauge | Inside diameter | 0.01 mm / 0.001 mm | Hole and bore checks |
| Infrared Thermometer | Surface temperature | ±1°C | Non-contact temperature check |
What is a Bore Gauge?
A bore gauge is a precision tool used to measure the inside diameter of a hole or bore accurately, often to 0.001 mm. Common types are dial bore gauges, telescoping gauges and digital bore gauges, chosen by the bore size and the accuracy needed.
What is a Sound Level Meter?
A sound level meter is an instrument that measures sound pressure in decibels (dB) to check noise levels in a workplace or environment. Class 1 meters are for precision and legal measurements, and Class 2 meters are for general workplace and environmental noise surveys.
How to Choose the Right Measuring Instrument
Selecting the correct instrument depends on a few key factors. Use these points as a quick guide:
- Dimensional accuracy: use a digital vernier caliper for general work, a micrometer for finer precision.
- Inside diameter: choose a dial or digital bore gauge to measure a hole or bore accurately.
- Electrical testing: pick a digital multimeter rated CAT III or CAT IV for safe panel testing.
- Temperature checks: use an industrial infrared thermometer for non-contact process surfaces.
- Noise audits: select a Class 1 sound level meter for precision or Class 2 for general surveys.
- Surface quality: use a surface finish tester to inspect roughness after machining or grinding.

A vernier caliper is a precision instrument that measures the internal, external and depth dimensions of an object to an accuracy of 0.02 mm. It has a main scale and a sliding vernier scale that together give the reading.
The least count of a standard vernier caliper is 0.02 mm (or 0.001 inch). It is found by dividing the smallest main-scale division by the number of divisions on the vernier scale.
A digital vernier caliper shows the reading directly on an LCD screen, while an analogue one is read from the main and vernier scales. Digital is faster and reduces reading error; analogue needs no battery.
A micrometer is used for high-precision dimensional measurement, offering finer accuracy than a vernier caliper. It uses a calibrated screw to close in on the workpiece, with resolution down to 0.001 mm on digital models.
An infrared thermometer is a device that measures the surface temperature of an object without touching it, by reading the infrared energy it gives off. It is used to check motors, bearings, electrical panels and process surfaces safely, often up to 500°C or more.
A non-contact infrared thermometer focuses the infrared light from an object onto a sensor, which converts it into a temperature reading. A laser pointer shows where it is aiming, giving an instant reading from a safe distance.
An infrared thermometer measures surface temperature from a distance without contact, while a digital contact thermometer must touch the object. Infrared suits hot, moving or live equipment; contact suits liquids and stable surfaces.
A bore gauge is a precision tool used to measure the inside diameter of a hole or bore accurately, often to 0.001 mm. Common types are dial bore gauges, telescoping gauges and digital bore gauges.
The least count of a typical dial bore gauge is 0.01 mm, and digital bore gauges can read to 0.001 mm. It shows the smallest change in bore diameter the gauge can measure
The main types of bore gauge are dial bore gauges, telescoping bore gauges and digital bore gauges. The choice depends on the bore size, the accuracy needed and the budget.
A sound level meter is an instrument that measures sound pressure in decibels (dB) to check noise levels in a workplace or environment. Class 1 meters are for precision work and Class 2 for general noise surveys.
Most standards set the safe workplace noise limit at 85 to 90 dB over an 8-hour shift. Above this, hearing protection and noise control are required, which is why regular sound level measurement matters.
A Class 1 sound level meter is more accurate and used for precision and legal measurements, while a Class 2 meter is used for general workplace and environmental noise checks. Class 1 has tighter tolerances.
A digital multimeter can measure AC and DC voltage, current, resistance and continuity on a single handheld device. Industrial multimeters are rated CAT III or CAT IV for safe use on electrical panels.
A surface finish tester is used to measure the roughness of a machined or ground surface, checking parameters like Ra, Rz, Rq and Rt against the required finish quality. It is used after machining, grinding or polishing.
