‍Frequently Asked Questions (FAQs)

‍

1. What is a Clean Room Monitor with External Humidity & Temperature Sensors?

A Clean Room Monitor is a multi-parameter monitoring system that continuously measures Differential Pressure (DP), Temperature (T), and Relative Humidity (RH) using an integrated pressure sensor and externally mounted temperature and humidity sensors. It provides accurate environmental monitoring while allowing the sensors to be installed exactly where measurements are required.

2. Why are external temperature and humidity sensors used?

External sensors provide more representative environmental measurements by allowing them to be installed directly inside the cleanroom or at the desired monitoring location. This improves measurement accuracy, especially when the display unit is mounted outside the monitored area.

3. What parameters does the monitor measure?

The monitor continuously measures:

• Differential Pressure (DP)
• Temperature (T)
• Relative Humidity (RH)

These three critical parameters help maintain stable environmental conditions in controlled areas.

4. Why is it important to monitor Differential Pressure, Temperature, and Humidity together?

Monitoring all three parameters ensures complete environmental control. Differential pressure maintains proper airflow between rooms, while temperature and humidity help protect product quality, maintain operator comfort, and ensure consistent manufacturing conditions.

5. Which industries use this monitor?

This monitor is commonly used in:

• Pharmaceutical Manufacturing
• Biotechnology Facilities
• Hospitals & Operation Theatres
• Cleanrooms
• Medical Device Manufacturing
• Research Laboratories
• Food Processing Plants
• Cosmetic Manufacturing
• Semiconductor & Electronics Industries

6. What are the advantages of external sensors?

External sensors offer several benefits:

• More accurate environmental measurements
• Flexible sensor placement
• Suitable for larger rooms
• Easy sensor replacement without changing the monitor
• Better monitoring in critical process areas

7. Can the display unit be installed outside the cleanroom?

Yes. The monitor can be mounted outside the cleanroom while the external sensors are installed inside the controlled environment, allowing operators to view readings without entering the room.

8. Does the monitor continuously monitor all parameters?

Yes. The monitor provides continuous, real-time monitoring of differential pressure, temperature, and humidity, helping detect environmental changes immediately.

9. Can high and low alarm limits be configured?

Yes. Alarm limits for all monitored parameters can be configured according to your cleanroom classification or process requirements.

10. How are alarms indicated?

The monitor can provide:

• Visual alarm indication
• Audible buzzer alarm
• On-screen alarm notifications

11. Can the monitor communicate with a Building Management System (BMS)?

Yes. The monitor supports RS485 Modbus communication, allowing easy integration with BMS, SCADA, PLC, and Environmental Monitoring Systems (EMS).

12. Is analog output available?

Yes. Optional 4–20 mA analog outputs are available for transmitting process values to external controllers or automation systems.

13. Can multiple parameters be displayed simultaneously?

Yes. The display shows Differential Pressure, Temperature, and Relative Humidity together, allowing operators to monitor all critical cleanroom conditions at a glance.

14. Is the monitor suitable for pharmaceutical cleanrooms?
