The Temperature & Relative Humidity (RH) Monitoring Test ensures that these factors are kept within the optimal range, helping to prevent contamination and ensuring product quality. Here’s a simple breakdown of this important cleanroom validation process.

What is the Temperature & RH Monitoring Test?

The Temperature & RH Monitoring Test checks whether the cleanroom maintains the correct temperature and humidity levels.

Both of these factors directly impact the cleanliness, performance, and stability of your products, equipment, and processes.

How is the Test Performed?

This test follows a straightforward procedure:

1️⃣ Use a Temperature & Humidity Meter:

A digital thermo-hygrometer is placed in multiple areas of the cleanroom to measure both temperature and relative humidity.

2️⃣ Record Readings:

The meter captures the temperature (°C or °F) and relative humidity (RH%) over time, allowing for accurate and continuous monitoring.

3️⃣ Compare with Standards:

The recorded readings are then compared against cleanroom standards.

Pass: If the temperature and RH fall within the acceptable range.

Fail: If the temperature or RH is too high or low, corrective actions are required, such as adjusting the air conditioning or installing dehumidifiers.

Recommended Temperature & RH Levels for Cleanrooms

Temperature:

Ideal temperature range is 18°C to 25°C (64°F to 77°F), though it can vary depending on the specific industry or cleanroom classification.

Relative Humidity (RH%):

The recommended RH range is 40% to 60% to prevent the buildup of static electricity and reduce the risk of microbial growth.

Equipment Used for Temperature & RH Monitoring

Thermo-Hygrometer:

This digital device measures both temperature and relative humidity in real-time.

Data Logger:

A data logger records continuous readings over an extended period, allowing for long-term monitoring of environmental conditions in the cleanroom.

Why is Temperature & RH Monitoring Important?

Prevents Moisture Buildup:

High humidity levels can lead to condensation, which may result in contamination or damage to sensitive equipment.

Ensures Stable Conditions for Products & Equipment:

Maintaining proper temperature and humidity is crucial for preserving the integrity of both products and equipment. It also minimizes the risk of static electricity and microbial contamination.

Supports Compliance:

Adhering to recommended temperature and RH levels is often a regulatory requirement for various industries, such as pharmaceuticals, electronics, and healthcare.

Final Thoughts

Controlling temperature and humidity is vital for the efficient operation of a cleanroom. By conducting regular Temperature & RH Monitoring, you ensure that your cleanroom environment stays stable, free from contamination, and compliant with industry regulations.

A well-controlled cleanroom is a high-performance cleanroom!
