Gas deadweight tester BL513

Oxygen gas is used in a large number of applications throughout the world. The aviation, medical and diving recreation industries use oxygen to enhance breathing while other industries use oxygen in applications such as welding. The use of oxygen poses many dangers and special care and handling need to be taken when using the pressure gauges, regulators and other equipment to keep them free from contaminants. The model BL513 water deadweight testers are perfect solution for oil and grease free oxygen pressure gauge calibration and measurements. KEY FEATURES • Water media operation • Accuracy 0.05%rdg, 0.02%rdg, 0.01%rdg, 0.005%rdg (customize) • Accuracy of LLR keeps same as ULR . That means one BL513 equals three other traditioinal DWT. • The piston and cylinder is tungsten carbide, which provides stability, durability, and low thermal coefficients and distortion. • Piston/cylinder design provides stability and repeatability • High quality needle valves provide optimum control and sealing • In-field user friendly APPLICATION • Primary pressure standard for oil-free gauge • Reference instruments in field.
