TOU Pressure calibration offers services for most pressure instruments.The calibration provided by our lab uses test equipment standards traceable to the National Institute of Standards and Technology (nist).
Our Client portal provides copies of your current and past calibration certificates as well as all current standard calibration records used in your procedure.
Pressure gauges are instruments used to measure the pressure of liquid or gaseous materials by calculating the force they would exert at a state of rest. The gauge displays the difference between the pressure in the area being measured and that of the surroundings, called the gauge pressure.
There are a variety of methods for measuring force, which means there are numerous types of pressure gauges. They can be classified on the basis of the principles used for measuring pressure, method of operation (mechanical or electrical), and the type of output (digital or analog).
- Commercial (Working) Pressure Gauges
These are ideal for most general purposes, commercial, and utility applications. There is a huge variety of commercial pressure gauges and they are typically found in refrigeration and HVAC systems, as well as the food and beverage industries. Due to their versatility, many end users and OEM appliances also use commercial pressure gauges.
- Industrial (Test) Pressure Gauges
These are made with stainless steel and are designed for monitoring the pressure of mediums that don’t cause obstructions in the system, like oil, gas, and other fuels. They are also commonly used in industries involved in manufacturing or processing of chemicals, mobile hydraulics, alternative fuels, and other petro-chemicals.
- High Precision (Master) Test Gauges
Testing and calibration laboratories use these precision pressure testing instruments for getting highly accurate results and measurements. These gauges are typically used in pressure monitoring panels and applications where the mediums will not cause obstructions or damage copper alloy parts
Why is Pressure Gauge Calibration Needed?
In industries, laboratories, and other commercial environments, pressure gauges are integral to processes. They are some of the most common instruments in use and almost every laboratory or manufacturer relies on them heavily. The sheer number of them in use leads to people assuming they are in working order, thus calibration is often overlooked or delayed.
Another essential function that depends on pressure gauges is safety. Employees rely on pressure measurements displayed by gauges to identify potential problems. Ensuring that pressure gauges are performing reliably, within reasonable limits of precision and accuracy, is absolutely essential for safeguarding quality and safety.
