The AI-DP1-1-TFT is a digital differential pressure monitor for continuous pressure monitoring in cleanrooms. Its color TFT display helps you verify the pressure relationship with adjacent areas.

It controls the direction of airflow between rooms of different cleanliness, so unwanted air stays out of the cleaner space.

It measures the pressure difference between its two connection points and shows the result on the display.

It shows the current reading and whether it is within range. The reading turns red during a violation, so a problem is visible from across the room.

Fit it where staff can see it easily, with the sensing tubes routed to the monitored rooms without leaks.

Connect it to the high and low pressure points, keep it free of kinks and leaks, and route it clear of damage or unwanted pressure effects.

Yes. The back box is about 40 mm deep and suits both modular and brick walls.

Yes, and the same applies to airlocks and gowning rooms. How you connect it depends on which space should be held at the higher pressure.

Yes. It verifies that the room holds the required pressure relative to its surroundings.

Pressure changes can point to airflow imbalance, door effects, HVAC faults, filter loading or control issues. Continuous monitoring catches them sooner than periodic checks.

Yes. Built-in high and low alarms include a buzzer with touch acknowledgement, and the reading turns red during a violation.

Yes. You can switch between the two units from the keypad.

Choose a range that covers normal operating pressure with enough resolution. A range that is too large reduces sensitivity, and one that is too small may not cover the operating condition.

Yes, through its communication or output options. This allows central viewing, alarms, trending, documentation and HVAC control.

Isolated RS485 Modbus is available as an option for digital integration. Please confirm the exact configuration against the model specification.

Yes. It is intended for continuous monitoring during production, storage, testing and other controlled operations.

Pharmaceutical plants, laboratories, hospitals, operating theatres, isolation rooms, biotech facilities, medical device and electronics manufacturing, and other controlled environments.

Yes. Match the range and configuration to the room classification, HVAC design and monitoring requirements.

It provides continuous local measurement against defined limits. When connected to a central system, values can be recorded for management, investigation and quality documentation.

Yes. Verify and calibrate it periodically, according to your accuracy requirements and quality procedures.

It reduces the need for frequent manual readings, but your established verification, calibration and documentation procedures still apply.

An indicator gives a local reading. A monitor adds a TFT display, alarms, communication and automation integration.

Both measure and alarm. The TFT shows the reading on a 3 inch screen that turns red during an alarm, while the LED version has a 4 digit readout. The TFT is better for viewing from a distance.

Facility managers, pharmaceutical manufacturers, HVAC contractors, consultants, validation and QA/QC teams, hospital engineers, lab managers and BMS integrators.

Clear digital readings, visual alerts, continuous monitoring, suitability for positive and negative pressure, and integration with building systems.

Consider the required range, display, alarms, communication, outputs, installation location and application. The Cleanroom Monitors team can help with configuration.
