Latest price list of differential pressure gauges used in medical clean rooms

1. Why It Is Necessary to Monitor the Price List of Differential Pressure Gauges in Medical Cleanrooms

1.1. The Importance of Pressure Differential in Medical Environments

In medical environments – especially in areas such as operating rooms, ICUs, isolation rooms, or pharmaceutical storage – maintaining a stable pressure differential between areas is mandatory in order to:

• Prevent cross-contamination between clean and contaminated areas
  
• Ensure compliance with ISO 14644 and GMP-WHO cleanroom standards
  
• Maintain unidirectional airflow from the cleaner area to the less clean area
  

The differential pressure gauge is the device that provides real-time monitoring of this pressure difference. Without it, the cleanroom system operates “blindly,” which can easily lead to:

• Severe cross-contamination
  
• Non-compliance with medical standards, resulting in failed inspections
  
• Health risks for patients and medical staff
  

Therefore, every medical cleanroom project must be equipped with an appropriate differential pressure gauge system – both to meet environmental control requirements and to comply with periodic inspection and validation.

1.2. The Need for Real-Time Price Updates

Since the healthcare sector usually operates on a project basis (hospitals, pharmaceutical plants, testing centers, etc.), regularly updating the latest differential pressure gauge price list is mandatory for:

• QA/QC teams: to plan equipment calibration and maintenance
  
• Procurement departments: to select the right model within budget
  
• Investors/Estimators: to build realistic cost projections and avoid budget overruns
  

However, the cleanroom equipment market fluctuates due to:

• Exchange rate and import tax changes
  
• Product lifecycle changes (discontinuation or release of new models)
  
• Promotions/discount policies for projects
  

Therefore, companies and contractors need to track price lists in real time, prioritizing sources that update directly from authorized suppliers to avoid purchasing outdated stock or falling for “fake” quotes on the market.

2. What Is a Differential Pressure Gauge? How Many Types Are There?

2.1. Operating Principle of Differential Pressure Gauges

A differential pressure gauge is a device used to measure the pressure difference between two areas – typically across the wall or door separating zones in a medical cleanroom.

Basic operating principle:
When the pressure between two areas differs, the device senses this difference and displays it through:

• A pointer mechanism (for mechanical types)
  
• A digital screen or output signal (for electronic types)
  

Monitoring this pressure difference is crucial to ensure that air always moves in the controlled direction (from the cleaner area to the less clean area), thereby maintaining sterile conditions, especially in:

• Operating rooms, ICUs
  
• Sterilization and packaging areas
  
• Pharmaceutical weighing rooms
  

2.2. Classification by Construction: Mechanical and Electronic

Currently, there are two common types of differential pressure gauges on the market:

• Mechanical Differential Pressure Gauge
  
  
• Uses a pointer and scale to display the pressure difference
  
• Requires no power supply
  
• Advantages: durable, easy to install, low cost
  
• Disadvantages: no signal output, difficult to integrate with automation systems
  
• Suitable for individual monitoring points that do not need BMS integration
• Electronic Differential Pressure Gauge
  
• Displays readings digitally or on an LCD screen
  
• Equipped with sensors – can output 4-20mA or Modbus signals
  
• Can connect to audio-visual alarms or centralized monitoring systems
  
• More expensive but feature-rich
  
• Suitable for hospital and pharmaceutical plant projects that require centralized monitoring
  

2.3. Classification by Pressure Range

Depending on the installation location and control level, differential pressure gauges are available in common measurement ranges such as:

Note: It is important to select the proper pressure range to ensure accuracy and avoid exceeding the gauge’s operating limit.

3. Factors Affecting the Price of Medical Differential Pressure Gauges

3.1. Type and Technology

The first factor that affects price is the type of device:

• Mechanical differential pressure gauges: lower price, usually from 2–4 million VND.
  
• Electronic differential pressure gauges: integrated with more features, priced from 6–10 million VND depending on configuration.
  

The more advanced the device, the better its display, data storage, and connectivity capabilities, which increases production and retail costs.

3.2. Accuracy and Pressure Range

Models with higher accuracy (±1–2% FS) will be more expensive than standard types (±5%).
A wider measurement range (±250Pa, ±500Pa) requires more precise sensors, leading to higher costs.
In medical environments, ±1% accuracy is typically the minimum requirement, especially in areas such as operating rooms and ICUs.

3.3. Additional Features: Alarm, Display, Signal Transmission

The following features can increase the device price by 20–50%:

• Audio/visual alarm when differential pressure exceeds the set threshold
  
• LCD screen display instead of mechanical pointer
  
• Integrated 4–20mA or Modbus RTU output
  
• Data logging and transmission to a centralized monitoring system (BMS)
  

Some high-end models even allow remote calibration or have anti-tamper functions.

3.4. Origin and Brand

Devices from the USA, Japan, and Germany are highly stable, durable, and widely used in GMP-compliant facilities.

Products from China or Vietnam are more affordable, but their accuracy and warranty must be carefully verified.

3.5. Cross-Contamination Prevention and Medical Safety

Models used in hospitals or pharmaceutical plants need:

• Dust-resistant design, smooth surfaces for easy cleaning
  
• Housing materials resistant to chemicals (alcohol, peracetic acid, etc.)
  
• Particle-free construction (does not generate airborne particles)
  
• Compliance with standards such as CE, RoHS, ISO 9001
  

These requirements make medical-grade devices more expensive than similar products used in general industry.
