Temperature Monitoring: A Crucial Aspect for Industries

Temperature monitoring is a pivotal aspect across various businesses and industries. It plays a vital role in ensuring the safety and quality of products and processes. In this context, temperature is one of the most significant parameters to keep under control. This is particularly true for the food industry, where consistent temperature regulation can make all the difference in quality and safety. In this article, we will delve into two major types of temperature monitoring: manual and automated, examining their pros, cons, and the transition between the two.

What we will cover:

Manual Temperature Monitoring System

The manual temperature monitoring system is a long-standing method for tracking temperature in various settings. It’s a traditional approach that employs basic devices like temperature gauges, frequently used for measuring the temperature of a product, and necessitates the consistent use of recording and logging devices to manage temperatures.

The operation of a manual system requires a thorough process, encompassing multiple checkpoints, regular observations and comprehensive data collection. This necessitates continuous vigilance and diligent documentation of temperatures, either done entirely by hand or with the assistance of a manual logging device.

In this traditional method, temperature measurements are often logged onto paper using a pen, a method that may seem outdated in today’s digital age but is still widely practised in many industries. Some businesses also opt for manual data entry into digital devices like tablets or PCs, but the common thread is that all these procedures require direct human involvement.

The data collected from these manual evaluations is then subject to analysis. This review helps identify any potential issues or discrepancies in the temperature of the product or process, serving as a necessary step to ensure quality control and safety standards.

The manual system has been the staple technique in various industries, ranging from food businesses to equipment-intensive sectors, to comply with differing regional standards. It requires manual labour dedicated to regularly checking temperatures, and capturing this data either on paper-based logbooks or through manual input in digital devices.

However, in recent years, there has been a growing debate over the benefits and drawbacks of traditional temperature monitoring systems. Many businesses are reassessing their methods in light of technological advancements and the increasing need for efficiency and precision. Despite the simplicity and directness of manual temperature monitoring, it comes with its own set of challenges, including human error, potential forgetfulness, labour intensity, lack of real-time alerts, and difficulties in maintaining an audit trail. These considerations have sparked ongoing discussions and have encouraged many to reevaluate their temperature monitoring strategies.

Advantages of Manual Temperature Monitoring

    1. No Technology Required: One significant advantage of manual systems is their independence from technology. They do not require any advanced software or devices to operate, making them accessible in resource-limited environments.

    2. Ease of Use: The simplicity of manual methods means they are easy to implement. Employees require minimal training to understand how to take readings and record them accurately.

    3. Regular Inspections: Manual monitoring ensures regular inspections of equipment and storage facilities, which can encourage diligence and attention to detail among staff.

Drawbacks of the manual temperature monitoring system

When we evaluate old-fashioned manual temperature monitoring systems with state-of-the-art advanced temperature monitoring practices, we will find some drawbacks that prevent businesses from performing efficiently. These may include but are not limited to inefficiency, multitasking, extra labor, human error, inaccuracy and lack of real-time data or proper records.

Let’s discuss them one by one. 

1. Require intensive labor and a strict schedule

Monitoring temperature regularly is a tiresome and difficult task, and it involves a lot of time to measure and record the temperature of each equipment on the floor. The labor needs to follow a strict schedule to monitor and record temperature which requires total commitment to avoid any problematic situation.

It requires someone to be present, recording the temperatures and then documenting all that data by hand on logbooks or sheets, which is overwhelming for the employees at times. 

2. You have to be sure that it is accurate

While logging temperature, you must ensure that the data you collected is correct, on time and recorded according to the specifications given in the compliance framework.

You may be asked to present these logs to the food inspector when he comes to examine your premises and determine whether you are following the set guidelines. Any discrepancy here can endanger both your business and your reputation.

3. Intermittent checks can lead to catastrophe

Manual checks only occur at certain intervals of the day, and the employees are not bound to watch the temperature around the clock. So, you may not know what happens between these inspections. What if the electricity outage hits? What if any system or equipment malfunction occurs in these intervals? Or what happens if your employee gets too busy or lazy to perform the routine checkup?

The temperature fluctuates throughout the day for so many other reasons for example, people open and close the doors to walk-in freezers, refrigerators, and storage pantries. Manual checkups usually overlook these issues, which can sometimes be terrible, impacting the food integrity and quality.

4. There is no audit trail for this manual process

      • Lack of real-time data and any significant change in temperature readings that were not recorded is a serious concern to the regulatory bodies. The absence of this critical data can lead to hazardous situations, and you will be left with no other option but to discard or waste the food items.
      • The manual checklist also has limited information of temperature readings only. These do not record and maintain the images and any other important information they can be helpful while the inspections are in progress.
      • Useless piles of hard copies and lost paperwork will not be helpful when a health inspector comes for the assessment. It is also difficult and time-consuming to retrieve data for analysis for the past years, months or even days.

5. Inventory rotation is a challenge

Businesses often face challenges when no technology is involved in monitoring their inventory temperature data which helps them maintain its integrity and quality over time. Their inability to detect real-time temperatures prevents them from moving the inventory in time and prevents potential loss and damage.

It’s difficult enough to keep track of temperature readings when you’re in charge of a single busy restaurant. This can be more complicated and tiresome if you manage a whole food chain or franchise with multiple locations.

Although analog sensors are considered the most cost-effective system to ensure safety compliance, they are a thing of the past since now automated versions of this technology have been launched.

Automated Temperature Monitoring System

Manual temperature tracking with an analogue system is time intensive and prone to mistakes. A digital temperature monitoring device eliminates the need for man hours, and it also eliminates the possibility of human errors. If you need to follow food safety compliance standards, a wireless temperature monitoring system is your best option for success.

The state-of-the-art automated temperature monitoring systems can transcend any business to the next level. They are cost-effective and HACCP-complying systems that ensure there is no waste of time and resources.
