In any vacuum-based process, the pressure gauge is your system's eyes. If it drifts, responds slowly, or fails to repeat readings consistently, your product quality suffers.
The CX-PRN12 Vacuum Pressure Gauge is engineered specifically for air and nitrogen applications. It delivers fast response, excellent repeatability, and rugged construction — all in a plug-and-play package that gets you running in minutes.
Here's why it's becoming the go-to choice for coating lines, semiconductor tools, and R&D labs.
A vacuum coating facility was struggling with inconsistent film thickness. Their existing gauge responded too slowly and showed significant reading drift between batches — especially in the critical 0.1–1000 Pa range.
After switching to the CX-PRN12, they saw immediate improvements:
| Challenge | CX-PRN12 Solution |
|---|---|
| Slow response caused pressure overshoot | <100 ms response kept pressure locked in |
| Readings varied batch to batch | ±2% repeatability ensured consistency |
| Installation was a hassle | Power adapter included – up and running in 15 minutes |
| Flange mismatch | Standard DN16 ISO-KF fit perfectly (custom options available) |
Their production lead summed it up: "Finally, a gauge that just works — no drift, no delays."

The CX-PRN12 is constructed with durability in mind. All vacuum-exposed materials are carefully selected for corrosion resistance and low outgassing:
SS316L Stainless Steel – superior corrosion resistance for the chamber body
Tungsten & Kovar Alloy – matched thermal expansion prevents seal failure
Glass – reliable electrical insulation
This material combination ensures long-term stability even in demanding industrial environments.
| Parameter | Range |
|---|---|
| Operating Temperature | 0°C – 45°C |
| Storage Temperature | -10°C – 75°C |
This gauge is the right fit if your system:
Uses air or nitrogen only (not for oxygen-rich or flammable gases)
Operates in the 0.1 Pa to atmospheric pressure range
Demands fast (<100 ms) and repeatable (±2%) pressure readings
Needs a cost-effective, reliable solution without unnecessary features
