TEMPERATURE CALIBRATION SERVICES

Temperature calibration is a crucial technical process that establishes the correlation between the temperature value measured by a standard and the temperature value of the measuring device. This process allows for the evaluation of measurement errors and the determination of precise measurement parameters of the device. Calibration is typically conducted at multiple temperature points to ensure linearity. If the measurement error falls within the acceptable range or meets the usage requirements, the device can be used as usual. However, if the error exceeds the permissible limit or fails to meet the usage requirements, appropriate actions must be undertaken, such as adjustment, repair, or replacement.

The necessity of calibrating temperature devices spans across various fields. As with all measuring instruments, temperature measuring devices require regular calibration to guarantee accurate measurements. Calibration activities provide insights into the operational capability and condition of the device, forming the basis for decisions on continued usage, repair, or replacement of the device, thereby ensuring product quality and efficient production.

Temperature is the most prevalent variable in the industry and is measured frequently. It can significantly influence the physical properties of materials, significantly affect the quality of the products, the amount of energy consumed in the process, and the level of environmental emissions. 

In different industries, different products need to be produced under specific conditions. If the temperature deviates too much, either too high or too low, it can adversely affect the end product, potentially leading to total failure and wastage of raw materials. Similarly, extreme temperatures, whether hot or cold, can cause metals to expand or contract, resulting in potential issues. 

Moreover, any manufacturing process that involves the use of chemicals must be conducted under suitable conditions. Fluctuations in temperature can alter the rate of chemical reactions. If the temperature is not accurately controlled, the chemical process may not proceed as planned or may not occur at all.

Temperature-measuring devices in industrial processes are often exposed to harsh operating environments, which can affect their performance and the performance of the sensors over time. To ensure these devices operate with the desired accuracy, verification, maintenance, and periodic calibration are necessary. Periodic scheduled calibration combined with regular checks offers several benefits:

• Ensuring the device provides accurate information, which in turn ensures necessary production conditions, optimizes production operations with uniformly high-quality products, and ensures the correct operation of the plant’s safety system, thereby maintaining the enterprise’s reputation.
• Linking measurement tools with measurement standards to ensure the uniformity and accuracy of the measurement, ensuring that the results obtained from all temperature measurement devices involved in the process are accurate and reliable.
• Determining the error and the uncertainty of the measuring device.
• Creating conditions to help your business pass internal and external evaluations.
• Allowing for the early detection of equipment that does not meet quality standards, operates abnormally, or is broken. This enables timely repair or replacement of equipment, ensuring the quality of the product and the smooth continuation of production.

Mechanical thermometers / Digital thermometers

A thermometer is a tool used to measure temperature and indicate the temperature of a specific application or condition.

Temperature transmitters 

It is an intermediary device that helps convert the raw signal from a temperature sensor and sends it to a control center or controller. This device not only amplifies but also converts it into a form suitable for display. 

Digital and analog temperature indicators

It is a device that provides a visual display of temperature readings from temperature sensors

Thermocouple & Resistance Thermometers / Resistance Temperature Detectors (RTDs)

They are widely used temperature sensors in the industrial sector. They are primarily designed to measure unknown temperatures, components, or various physical substances. Their role extends beyond mere measurement, as they also monitor thermal quantities and relay this critical information back to a centralized control hub. 

Thermo-Hygrometer

It is a specialized device that measures both temperature and humidity. It can measure the ambient temperature like a thermometer and also provide humidity measurements like a hygrometer.
