BL513 WATER MEDIA DEADWEIGHT TESTER 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. ■ All wet pats, special pressure connections are rinsed with an extractant ■ All valves and fittings are cleaned for residual hydrocarbon determination ■ High quality needle valves provide optimum control and sealing ■ Any accessories are also cleaned and inspected, usually through an ultrasonic method immersed in the solvent. ■ Accuracy: 0.02% reading, 0.01% reading ■ Piston material: Tungsten carbide ■ Cylinder material: Tungsten carbide ■ Mass material: 304 stainless steels ■ Hydraulic base material: Stainless steel, aluminium ■ Seal material: Buna-N, Cu Alloy ■ Medium: Deionized water ■ Gravity: Standard 9.80665 m/s2, or custom ■ Pressure units available: MPa (bar and psi is optional) ■ Connector: Metric, (NPT and BSP is optional) PRESSURE SELECTABLE SHEET ■ BL513 Water deadweight tester base ■ Piston cylinder unit ■ Mass carrier plate ■ 304 stainless steel mass set OPTIONAL ACCESSORIES AND SERVICES ■ Customize 0.005% of reading accuracy ORDERING MODEL NUMBER ■ Calibration of oil grease free pressure gage ■ Chemical, pharmaceutical, aviation industry Balun Technology Co., Ltd T: +86-10-6240 6768 E: [email protected] Add: 1322, F/3, Bldg 1,33 Zique Rd, Haidian,
