LOW DIFFERENTIAL PRESSURE GAUGE

Compact Diaphragm Gauge Tailored for Sensitive Pharma & Clean‑Room Ventilation

Overview

The LOW DIFFERENTIAL PRESSURE GAUGE from AIMS Control is engineered for ultra‑low pressure monitoring where even minor deviations can compromise product quality. Purpose‑built for pharmaceutical clean rooms, laminar flow benches, and critical HVAC zones, this compact, diaphragm‑operated instrument offers precise readouts down to 6 mmWC / 60 Pa / 0.25″ WC—making it the ideal safeguard for sterile environments.

Key Features & Benefits

  • High‑Resolution Diaphragm Design

Sensitive capsule element converts minute pressure changes into smooth, repeatable pointer movement.

  • Clean‑Room Ready

Smooth, crevice‑free bezel simplifies wipe‑downs and contamination control.

  • ± 2 % Ascending Accuracy

Ensures tight process control across the full span—even at the lowest end of the scale.

  • Flexible Mounting

Choose back or side connections to integrate seamlessly with panel, wall, or duct installations.

  • Dual 1⁄8″ NPT (F) Ports

Two process connections allow effortless differential hook‑up or static pressure reference.

  • Compact DN100 Dial

Large enough for distant visibility yet small enough to fit crowded equipment racks.

Why Specify This Gauge?

  1. Ultra‑Low Pressure Mastery – Detects pressure differences that standard gauges cannot register.

  2. Sanitary Surface Finish – Designed to satisfy stringent pharma GMP and ISO 14644 clean‑room norms.

  3. Versatile Hook‑Up – Back or side porting fits both panel gauges and in‑line duct monitors.

  4. Backed by pressure gauge manufacturers in Gujarat , India – Rapid delivery and localized service support.

Typical Applications

  • HEPA filter integrity monitoring

  • Clean‑room differential pressure control

  • Biosafety cabinets & isolators

  • Laminar flow benches

  • Pharmaceutical tablet‑press enclosures

  • Hospital isolation wards & ICU suites

Compliance & Quality

Every LOW DIFFERENTIAL PRESSURE GAUGE undergoes five‑point calibration against NIST‑traceable masters. All wetted surfaces are degreased and batch‑certified for clean‑room use. Test certificates and IQ/OQ documentation are available upon request.
