What Equipment Requires Calibration?

Home // What Equipment Requires Calibration?

Instrument calibration is an essential process in determining your equipment’s accuracy and making any necessary adjustments to get a more precise result from them. Over time, your equipment can begin providing less accurate readings due to mechanical shocks, exposure to extreme pressure and/or temperatures, and other harsh operating conditions. 

You should get your instruments professionally calibrated on a regular basis as inaccurate readings may not fully represent the dangers of unsafe working environments. The recommended frequency of calibration may vary, depending on manufacturer recommendations, however generally for most items no longer than 12 months is recommended. Some extremely stable items with limited parts and movement, no dissimilar metals and other factors that reduce the likelihood of drift, and are continuously stored in a controlled environment; calibration intervals over 12 months may be considered. 

In this blog, Mobile Test ‘n’ Cal will discuss the various types of calibration and what equipment requires them.

Electrical calibration

Electrical calibration checks the accuracy of an electrical instrument’s full array of functions and the full range within each function. Only competent professionals should carry out this task. Electrical equipment requiring calibration includes:

  • Insulation testers
  • Clamp meters
  • Counter timers
  • Multimeters
  • Multifunction Testers
  • Oscilloscopes
  • Data loggers
  • Loop testers
  • Residual-current devices

Pressure calibration

Calibration professionals work with pneumatic and hydraulic pressure across a range of sectors with various types of pressure gauges, transducers, balances and other devices. 

Frequently calibrated pressure instruments include:

  • Barometers
  • Analogue and digital pressure gauges
  • Test Gauges
  • Digital Indicators
  • Pressure Transmitters
  • Pressure Calibrators
  • Pressure Transducers

Temperature calibration

All processes where temperature readings play a critical role require temperature calibration. The calibration tech performs this in a controlled environment with state-of-the-art and highly precise equipment. Examples of equipment that requires periodic calibration include:

  •       Furnaces and chambers
  •       Data acquisition systems
  •       Weather stations
  •       Thermal cameras
  •       Thermometers and thermocouples
  •       Dial thermometers
  •       Thermistors and platinum resistance thermometer
  •       Infrared meters

Mechanical calibration

This process involves calibrating a number of elements such as force, mass, volumetric dimension, angle, flatness, torque and vibration in a temperature-controlled facility. Some of the most frequently tested instruments for mechanical calibration include:

  •       Torque tools (screwdrivers and wrenches)
  •       Load cells and force gauges
  •       Micrometers
  •       Height gauges
  •       Vernier calipers
  •       Balances and scales
  •       Weight and mass sets
