Why Go in for Autoclave Calibration Services

Autoclaves are beneficial pressure chambers used in medical, chemical, and laboratory industries. They are used to carry different processes, which require non-ambient pressures and elevated temperatures. The successful use of an autoclave depends on its calibration or operating settings. As a customer, when your organization requires autoclave calibration services, it is important for you to understand the calibration process, its importance, and methods. The details of these are given below.

What is Calibration, and Why is it Important?

Autoclaves are designed with sensors such as thermocouples or transducers. Calibration is the procedure used to adjust the response of the sensor to a range that corresponds with a NIST standard (National Institute of Standards and Technology). A NIST-traceable device like an oil bath, a dry block, or a temperature probe is used in the autoclave calibration process. The sensor’s response is compared with a previously calibrated device. The calibration of this previous device should be at least 5 times as accurate as the autoclave being calibrated. The reason why calibration is given high importance is that it ensures consistent results from any process that utilizes autoclaves.

How is Calibration Measured?

Generally, calibration is measured in points, ranging from 1 to 3. Depending on the number of points, the calibration instructions will vary. Each point type is different from the other. This is explained with the information given below.

  • Single Point: As the name suggests, single point calibration provides accuracy only for a single, specific point. For example, when the chamber is being pressurized at only one level, then single point calibration will be used.
  • Two Point Calibration: Another method is to take two point measurements, and check the increase and zero offset. This is a popular method, as it is convenient to perform, and can be completed quickly.
  • Multipoint Calibration: This method involves taking three or more points of measurement and performing linear regression. Linear regression is a technique used to find a straight line, which will fit linear function values.

The autoclave calibration method should be chosen and performed depending on the application environment, the pressure, and temperature range. For precise results, it is advisable to find a autoclave calibration services provider. They can understand your requirements and provide the best solution.
