Leak Detectors

Buy a leak detector to ensure safe operation of your equipment
By Howard Robertson A leak detector is a key device, as fluid leakage harms your products and pollutes the environment. The leak detection business has evolved from a simple bubble detection system to modern helium detection techniques. Modern leak detection equipment is more sensitive, less power consuming and more compact compared to the conventional bubble or air leak test equipment.

The industries for which leak detectors have become a necessity are aircraft, automotive, gas production, medical, petrochemical and HVAC (heating, ventilation and air conditioning). You can buy a leak detector that alerts you with visual, audio or digital signals.

Some of the important parameters you must consider before purchasing a leak detector are:

1. Fluid flowing through the system
2. Required sensitivity and reliability of the leak detector
3. Operating temperature, pressure and viscosity ranges
4. Required type of output: visual, audio or digital

Buy a helium leak detector for vacuum leak detection

A helium leakage detector is the best choice for identifying vacuum leakage for your system. Helium leak detection, a modern sophisticated leak test technique, also offers the benefit of being a user friendly and cost-effective instrument.
Try:  INFICON offers a variety of helium leak detectors in mobile, portable and cabinet models. MKS Instruments is another manufacturer of battery-operated helium leak detectors. Alcatel Vacuum Technology produces an extensive range of helium leak detectors that have high sensitivity.

Buy an ultrasound leak detector for gas or air leak detection

Ultrasound leak detectors are most suitable for the testing of compressed air systems. You can also use a refrigerant leak detector in the HVAC industry. The ultrasound leak detector indicates the leak by giving an audible buzz tone. Some ultrasonic detectors also have digital output facility.
Try:  UE Systems offers ultrasonic inspection instruments including leak detectors. EXAIR Corp. is another supplier of ultrasonic leak detection devices for pressure vessels and compressed air piping. Superior Signal Co. offers ultrasonic leak detectors for industrial compressed air leakages.

Buy a liquid leak detector

Liquid or water leak detection equipment is important for industrial, office and domestic requirements. Liquid or water can ruin your machinery, computers or even buildings. Install proper liquid leak detectors to avoid such problems.
Try:  General Pipe Cleaners manufactures detectors for liquid leakages under the floor surface. You can also buy a spot or lineal leak detector from Hydro-Temp. Invetex Corp. provides water leak detectors in the form of ceiling tiles and pads. Dorlen Products is another reputable manufacturer of water leak detection devices.

Buy a suitable leak detector from a retailer

You can buy new or used leak detection equipment from a retailer. Retailers also provide a list of manufacturers of ultrasonic leak detectors and helium leak detectors.
Try:  The Test Equipment Depot is a retailer of new or pre-owned testing equipment, including leak detectors. Duniway Stockroom Corp. provides leak detectors and their accessories. You can find a list of various leak detector manufacturers on ThomasNet and IQSDirectory. 

• Calibrate the leak detector regularly.
• Consider the quality of the leak detector as the main purchasing criteria as an improper leak detector may cause irreparable damage.
