Using The Right Calibration Process
Have you ever wondered if your organization is utilizing the correct temperature calibration method for your application? In many industries, the calibration of ovens, refrigerators, freezers, and controlled environments is critical. This equipment often houses food, pharmaceuticals, medical devices, and other consumer products. There are various methods for calibrating controlled environments, but we will be examining one point and temperature uniformity studies.
First, the one, or single, point calibration method is the simplest type of calibration that can be used to meet some temperature regulation and guideline standards. A point calibration is where your equipment is measured in a specific point(s). This as before is the simplest of the calibration methods as it is usually shorter and doesn’t require as many processes.
Temperature Uniformity Study
Temperature uniformity studies or temperature mapping is the process of mapping the differences in temperature within a single temperature-controlled system. Although the center of this type of equipment is generally the most constant, the temperature in the corners can vary greatly from that constant. The variation is caused by numerous factors such as the quantity and type of material inside, the opening and closing of any doors, nearby cooling, heating systems, etc. This variation in temperature can be described as a gradient, as the temperature in the center in the middle is the most accurate growing outward to potentially less. Do you know what the gradient spread of your equipment is? Temperature mapping is the more complex of the two calibration methods but also the most accurate of the two.

What's Your Gradient Look Like?
For example, the spread on the right is showing high amounts of heat in the red area and grows colder as it moves away from the heat source. This can be a problem let’s say if you are baking something that needs a temperature of 500 degrees. The center will be at the correct temperature, whereas the sides could be much cooler making those items not at the correct temperature.

Both the point calibration and uniformity study are reliable ways to calibrate temperature. Depending on what your needs are and how big of an oven or heating equipment you are using a uniformity study may be the best way to go. We know temperature calibrations are vital to some business functions. If you need calibrations for your applications and equipment, contact us here!
