Microprocessor Temperature Controllers: Do They Make a Difference?

Refrigerators and cold storage equipment can be found in just about every pharmacy, lab, or clinical setting. But have you ever stopped to consider how accurately these units are performing? How well are they protecting and preserving the substances they store? What about service costs? And temperature-reading accuracy?


All these questions and more rise to the surface when considering the features of professional refrigeration. But perhaps all these questions can be answered by looking at one feature alone—the temperature controller. Why is this piece so important?


Let’s find out.  


What is the Function of a Temperature Controller?

A digital temperature control system tells you the temperature inside your unit. Generally, cold storage units calculate a specific range, from a factory set point to a certain fluctuation of degrees on either end.

The role of all temperature controllers is to regulate temperature. If the temperature has fluctuated from the original setpoint, the controller can send a signal through sensors to bring that temperature back to the desired range.

Different systems monitor temperature in different ways. But however the temperature is controlled, correct temperature devices are integral to the success of every cold storage unit.


Why Precise Temperature Control Matters

It comes as no surprise that cold storage exists to keep things cool—precisely cool. Some pharmaceuticals and laboratory substances are extremely sensitive to temperature fluctuations, however slight.

Yet the need for precise temperature controllers is often overlooked or undervalued. Why is this? Many people assume one temperature controller is the same as another. But is this true?


Let’s take a closer look.


Many sources acknowledge that traditional controllers such as analog controllers or mechanical thermostats do not provide exact temperature readings. Temperature readings on these controllers can fluctuate an unbelievable +/-10° from the dial set point. 

This is an enormous range of error, especially considering the delicate nature of many laboratory substances, pharmaceuticals, and vaccines. 


 Specifically in regards to vaccines, the Los Angeles Times states that “by one World Health Organization estimate, as many as half of the vaccine doses in previous campaigns worldwide have been thrown away because they were mishandled, unclaimed or expired.” This is a staggering amount of waste.


Much of this waste can be prevented with proper handling and precise cold storage regulation.


Introducing Microprocessor Temperature Control

So, what’s the alternative to inaccurate temperature readings and wasted substances? One relatively simple solution: microprocessor temperature controllers—the ultimate temperature reading device.

Microprocessor controllers have risen in the industry as the trusted standard for temperature monitoring and regulation. These extremely accurate controllers effectively monitor temperatures to tenths of a degree.

These devices work by capturing temperatures through an electrical voltage which is then converted into a digital format to be read on a screen. They function at an extremely fast processing rate, giving you precision, accuracy, and complete control all in one.


Why Old Temperature Controllers are Costing You

Older forms of controllers that don’t utilize these features may cost you more than they’re worth. Poor response time, inaccurate temperature readings, and low service life and reliability all contribute to the costs and challenges associated with older, less effective controllers.

For example, some digital controllers have a temperature difference of 1 degree. Microprocessor temperature controllers output a much higher degree of temperature accuracy, often at a 0.1 degree readout. This illustrates that the sensor and controls of your unit may be just as important as the unit itself.

If your control method does not maintain stability, it doesn’t matter how effective the cooling power of your equipment is. You need a combination of precise temperature controllers and quality cooling systems for your equipment to reach optimum success.


Analyzing and Upgrading your Equipment

So, what does all this information about controllers mean to you?


If your clinical setting or laboratory uses cold storage, perhaps it’s time to re-evaluate the equipment you use. If your establishment stores any kind of sensitive medical or scientific substances, microprocessor temperature control is highly recommended—if not critical—to prevent loss of money, time, and unnecessary waste.
