Description
The Sanitary Pressure Gauge (also known as Hygienic Pressure Gauge or Tri-Clamp Pressure Gauge) by Aavad Instrument Pvt. Ltd. is purpose-built for food-grade, pharmaceutical, biotechnology, and clean-room applications where product purity, surface hygiene, and CIP/SIP (Clean-In-Place / Sterilize-In-Place) compatibility are non-negotiable requirements.
The smooth internal diaphragm prevents media entrapment, bacterial growth, and cross-contamination — making it the definitive choice where hygiene validation and traceability are mandatory.

FAQs
1. What is a Sanitary Pressure Gauge?
A Sanitary Pressure Gauge is a hygienic pressure measuring instrument designed with a flush diaphragm and a Tri-Clamp (Tri-Clover) process connection for accurate pressure measurement in food processing, dairy, beverage, pharmaceutical, biotechnology, and other sterile process applications. Its hygienic design minimizes contamination and supports clean-in-place (CIP) and sterilize-in-place (SIP) processes.
2. Why does a Sanitary Pressure Gauge use a Flush Diaphragm?
A flush diaphragm eliminates dead spaces and cavities where product residue, bacteria, or contaminants can accumulate. This improves cleanability, hygiene, and process safety, making the gauge ideal for sanitary applications requiring strict cleanliness and compliance with hygienic processing standards.
3. What is a Tri-Clamp Connection?
A Tri-Clamp (Tri-Clover) connection is a hygienic quick-connect fitting widely used in the food, beverage, dairy, pharmaceutical, biotechnology, and cosmetic industries. It enables fast installation, easy removal, leak-free sealing, and efficient cleaning, making it the preferred connection for sanitary process equipment.
