Special Expert Gauges: Mcleod Gauge For Vacuum Measurement
McLeod Vacuum Gauges are trusted worldwide for their high-accuracy measurement of low vacuum pressures. Designed to measure pressures in the range of 10 mmHg to 0.01 mmHg | 1 mmHg to 0.001 mmHg | 10 mmhg to 0.001 mmHg, McLeod Gauges are ideal for applications requiring precise and reliable vacuum monitoring.
At Japsin Instrumentation Private Limited, we offer high-quality McLeod Gauges engineered for performance, durability, and consistency—perfect for laboratory, industrial, and research environments
What is a McLeod Gauge?
A McLeod Gauge is a primary standard vacuum gauge that operates based on Boyle’s Law, which relates pressure and volume of a gas at constant temperature. It compresses a known volume of gas and measures the resulting pressure, allowing for direct and accurate readings without the need for calibration against another vacuum gauge.
Key Features
- Measurement Range:
- 10 mmHg to 0.01 mm Hg
- 1 mmHg to 0.001 mmHg
- 10 mmHg to 0.001 mmHg
- High Accuracy & Stability
- No Power Source Required
- Unaffected by Gas Type (Inert or Reactive)
- Long Service Life with Minimal Maintenance
- Ideal for Calibration & Reference Standards
