Used PARR 1241 #9220931 for sale

PARR 1241 is a multi-purpose, low-cost laboratory device developed by PARR Instrument Company to measure the pressure of gases and liquids in applications ranging from laboratory experiments to process control. This versatile instrument is suitable for operation in a variety of temperature and pressure ranges. 1241 is equipped with a 6.2-cm2 window in a 2-cm diameter aluminum block designed to facilitate visual sample observation during the measurement process. This instrument is available with both manual and digital controllers that provide high accuracy and repeatability. Additionally, the internal memory of the digital controller can store calibration data and recall data from previous measurements. PARR 1241 consists of a stainless steel housing with a double-sealed bellow assembly. The bellow is filled with a silicone fluid to isolate pressure readings from ambient temperature changes, providing very accurate measurements. For measurements in hostile environments, the bellows assembly can be replaced with a double-sealed diaphragm assembly. 1241's sensing components are hermetically sealed within the aluminum block, allowing them to function in elevated temperatures and pressures. The sensing components consist of a movable tube and a spring-loaded sensing element that provide a linear output of pressure variations. Additionally, the stainless steel terminal block of PARR 1241 facilitates the connection of accessories and sensors to the device. 1241 is suitable for a variety of sampling methods due to its adjustable height marker and optional sampling valves. Fittings, valves, and tubing are available for operation in a variety of environments including vacuum systems, corrosive atmospheres, and high-pressure environments. PARR 1241 is an invaluable laboratory instrument that provides very accurate pressure readings and is suitable for a wide variety of applications including process control, laboratory experiments, and sample analysis.
