Techris Systems – Precision Pressure Measurement for Every Industry.

What is a Manometer or Pressure Meter?

A manometer, also known as a pressure meter, is a device used to measure pressure in gases or liquids. Whether you’re working in HVAC, laboratory settings, or industrial processes, understanding and controlling pressure is essential. At Techris Systems, we supply a wide range of digital manometers designed for accurate and reliable pressure measurement across a variety of applications.

How Does a Manometer Work?

Pressure is the result of force (F) applied over a specific area (A). The basic formula is:

P = F / A

The SI unit of pressure is the pascal (Pa), which equals one newton per square metre (N/m²). However, there are several commonly used units depending on the application:

Pascal (Pa), Kilopascal (kPa), Megapascal (MPa)
Pounds per square inch (psi)
Torr (mmHg)
Atmospheres (atm)
Bar

Manometers are engineered to measure this pressure, and many models are designed to detect differential pressure—the difference between two pressures—making them ideal for applications such as gas flow, filter monitoring, and pressure drops across systems.

Types of Pressure Measurement Gauges

There are three main types of pressure gauges, each designed for specific measurement needs:

Absolute Pressure Gauges – Measure pressure relative to a perfect vacuum
Gauge Pressure Meters – Measure pressure relative to ambient atmospheric pressure
Differential Pressure Gauges – Measure the difference between two points in a system

Analog vs Digital Manometers

Manometers can be broadly categorized into two types:

1. Analog Manometers

Analog manometers are typically lower-cost solutions, suitable where basic readings are sufficient and high accuracy is not essential. These are often used in non-critical applications or for educational purposes.

2. Digital Manometers

Digital manometers are the preferred choice for industrial and technical applications where precision, ease of use, and data readability are important. These instruments offer greater accuracy, often with selectable pressure units, backlit displays, data logging, and portability.
