Used ULVAC 531 #9004458 for sale

ULVAC 531 is a high sensitivity leak detector used to detect leaks in a wide variety of applications. It is primarily used to detect refrigerant gas leaks in applications such as refrigeration, air conditioning, and automotive systems. The detector utilizes a "filter" system to detect refrigerant leaks in gases with other elements present. 531 has an all-metal construction for durability, and it features a digital display for easy viewing of leaked gas levels. It also has a built-in alarm to alert the user when a leak is detected. The detector can be adjusted from 1 to 20 bar to measure the pressure range of the gas, and to increase or decrease the sensitivity of the detector. It also has a gas sampling valve to allow the user to pull samples of the gas for further analysis or to monitor leak levels. ULVAC 531 utilizes a diode array method for detecting leaks. This method uses a combination of electrical signals and heat, generated from the diode array, to detect the presence of gas leaks. The detector can detect gas leaks as small as 0.1 mg/m³. This is about 90 times the sensitivity of traditional leak detectors and can detect most refrigerants present in typical systems. 531 is powered by either batteriers or a standard AC power adapter. It features a set of earphones for private listening and a headphone jack. It also has an easy to read LED screen that indicates gas levels and settings. ULVAC 531 is a rugged, reliable, and easy to use leak detector that is ideal for the detection of very small leaks in a wide variety of applications. It is also very sensitive and could detect even miniscule amounts of gas leaking from equipment. The detector can be used in a variety of locations, including commercial and residential air conditioning and refrigeration systems, as well as automotive systems.
