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.
