Used VARIAN 925 VFT #71737 for sale

VARIAN 925 VFT is a compact, reliable and economical vacuum breaker and leak detector that helps detect and locate the presence of vacuum, gas and vapor leaks. This leak detector utilizes a combination of three internal components: a vacuum regulator, a pressure switch and a flow meter. The vacuum regulator is used to monitor and control the amount of vacuum within the system. The pressure switch is the main component of 925 VFT, as it is used to detect any drops in pressure or vacuum levels. In normal operation, the pressure switch should open when the pressure or vacuum drops below its setpoint. If a leak is present, the pressure switch will close and trigger an alarm to indicate the presence of a vacuum or gas leak. The flow meter of VARIAN 925 VFT is used to measure the rate of gas or vapor leakage. It is supplied with a flowrange adjustment knob for changing the sensitivity of the detector. This flowmeter is also equipped with a flow limit alarm that is set to the maximum allowable flow of the system. When the flow limit is exceeded, an alarm will be triggered. By monitoring the rate of flow, 925 VFT can help identify the approximate size and location of the gas or vapor leak. The main purpose of VARIAN 925 VFT is to help prevent costly damages due to vacuum or gas leaks. This leak detector is designed to be easy to install, highly reliable and cost effective. It is also designed to meet the toughest environmental and safety requirements. Compatible with many gas and vapor types, it is the ideal solution to help protect against the damaging effects of vacuum and gas leaks.
