Clean rooms need to be just that: clean. The best way to ensure this is by accurately monitoring the pressure, temperature, and the humidity of the room. Let’s take a deeper dive into why each of these is important:
Air pressure: This is one critical parameter to measure accurately because it will help determine what classification level the clean room is rated for as well as protect the people and products inside the cleanroom. Whether a high- or low-pressure clean room, maintaining accurate pressure monitoring ensures the environment will be able to protect against any contaminants entering the area (in high/positive pressure applications) or contaminants leaking out of the clean room (in low/negative pressure clean rooms).
Temperature: Temperatures in the clean room should be maintained at 69.8°F and not fluctuate more than 2 degrees. This is important for the comfort of personnel in the clean room. If the personnel inside the clean rooms either begin to sweat or shiver, these human responses to the environment can cause particles to be released into the cleanroom and result in contamination or human error. Contamination has the potential to compromise the production and materials within said cleanroom, and human error can cause inconsistent and poor results or processes.
Humidity: Without accurately monitoring humidity, you run the risk of several common issues occurring, which could directly impact the quality of the product in the room or losing ISO certification. Common issues seen with fluctuations in humidity include:
- Static charge – Having products in the clean room with a static charge result in issues such as comprised sanitation, where dust or fibers can become attracted to otherwise sterile products, essentially rendering them useless or worse, dangerous
- Metal corrosion – Any sort of degradation of the metals used in these rooms can be breeding grounds for bacteria and other airborne containments
- Condensation – Having solvents condense from a gas to a liquid may compromise the quality as well as the process control
- Bacteria growth – growth of bacteria will result in the clean room no longer living up to its name
- Comfort of personnel – If the personnel in these clean rooms are too hot and sticky, they will begin to sweat and become uncomfortable, which may result in costly mistakes that could translate to extended production times or even serious mistakes
If these variables are not accurately monitored or are done so in such a way that lacks quick response time, both safety and compliance now become an issue. If the clean room can’t accurately adjust to daily changes related to temperature, pressure, and humidity, people’s health and safety become what is at stake.
KS98-2 - By accurately monitoring these three variables, you can better understand where and when issues begin to arise before they have a catastrophic effect on the process or people working in the clean room. With the KS98-2 multi-function controller, you now have the capability of accurately and consistently controlling the conditions within the room. When using the controller, measuring, visualizing, and recording the information from any attached sensors allows you an easy-to-use localized all-in-one device. Tie all the sensors needed without the worry or hassle of running out of space or using multiple controllers, as this unit can handle a plethora of signals, from RTDs, mA, mV/V, and TC to name a few. This modular unit can also be expanded to measure the values from up to 12 dual channel IO extension modules, meaning you can hook up 24 sensors seamlessly and display the value of each of these locally. This can give you localized display of either 8 different locations within the clean room, or 8 clean rooms monitoring all three of these critical variables.
