Used VARIAN 938-41 #9081306 for sale

VARIAN 938-41 is a leak detector designed for use in detecting vacuum system leaks and other gas leaks. It uses a combination of acoustic sensors and an ultra-high frequency modulated signal to detect the presence of a leak in a pressurised or evacuated system. The device is typically used in applications where physical access to a component or joint is restricted or difficult. It is capable of aiding both the identification of the location and magnitude of any leak that is present. It is designed to work even in environments where there are other sources of acoustic noise present. VARIAN 938 41 leak detector uses a modulated ultra high frequency (UHF) signal to detect leaks. This signal is beamed onto the surface or joint under test, far exceeding the usual audible threshold. The signal radiates from the centre of the device and is reflected back to the instrument by sound waves passing through the material along with any leak gas molecules. The device is capable of detecting leaks by sound up to 0.6 mm in diameter. The signal is calibrated to be only triggered when a leak is present and a concentration of escaped gas is detected by the device. When a leak is present, the signal is processed by the instrument and a "Leak Detected" alert is displayed to advise the operator of a positive leak detection. 938-41 leak detector requires no calibration prior to use and its feature-set includes a robust signal processing system which is able to eliminate other extraneous acoustic noises, allowing the measurement to be focused and accurate. The instrument is supplied with an LCD display and a control knob that can be adjusted to set the alarm threshold in order to optimise its sensitivity to suit different applications as required. 938 41 is powered by 9V batteries which provide a continuous operating time of up to 8 hours. An audio output is also present if required. VARIAN 938-41 leak detector has been designed for use in a wide variety of applications. It is suitable for use in industrial, scientific and medical environments where the detection of vacuum and gas leaks is necessary. It is also capable of being employed in semi-conductor manufacturing processes such as plating, chemical vapour deposition and etching. The instrument is capable of being used as a stand-alone leak detector when connected directly to the part being tested. It can also be employed with an external vacuum pump or any other pressurised equipment defined by the user. VARIAN 938 41 is an effective and reliable leak detector ideal for use in a variety of leak detection requirements across many different industrial and laboratory applications. It provides reliable and accurate leak detection performance with the ability to adjust the sensitivity settings precisely, and it has a battery life of up to 8 hours which makes it suitable for continuous use.
