| Solid state mercury-free digital regulators Model:GSF3-PT-61 | Cat.No: |
| Solid state mercury-free digital regulators supervac site:zxqc.cn supervac site:hd315.org supervac site:midwest.com.cn Solid state mercury-free digital regulators are designed for precise measurement and control for a range of laboratory vacuum applications. They are preset to control at 300mm below atmospheric pressure as needed for viscous asphalt testing with Asphalt Institute, Cannon-Manning, and Modified Koppers vacuum viscometers, but may also be user reset to control anywhere in the range from 1-410mm below atmospheric pressure. An LCD screen displays vacuum in mm Hg or any of nine other units. The vertical configuration is designed for convenient display and keypad access while minimal counter space is used. Two models are available. Model PT-61 100 Watt is for regulation of user's existing vacuum system. Model PT-62 175 Watt is equipped with an internal vacuum pump and requires no external vacuum source. Both have housings of enameled steel supported with rubber feet. Overall Dimensions: 6.75x18x18.5in （172x458x470mm）, DxH. Est. Ship Wt.: 45lb （20kg）. Purpose:Research | Solid state mercury-free digital regulators Model:GSF3-PT-61 |
| Model LP-14 water determination apparatus measures water content Model:GSF3-LP-14 | Cat.No: |
| Model LP-14 water determination apparatus measures water content supervac site:zxqc.cn supervac site:hd315.org supervac site:midwest.com.cn Model LP-14 water determination apparatus measures water content of asphalts, oils, greases, tars, and other petroleum and bituminous products. Water is distilled under reflux with a water-immiscible solvent, then condensed and separated in a graduated trap. Main components of the system include a special metal still, an adjustable ring burner for all gases with ports on its inside circumference, a 400mm glass reflux condenser, and a glass trap with stopcock graduated by 0.1ml-10ml then by 0.2ml-25ml capacity. The 1qt （0.9L） still is made of lightweight aluminum alloy for best heat conduction. The gasketed cover is fastened by a heavy yoke with steel compression screw. Inside Dimensions: 3.5x6in （89x152mm） dia. x depth. Also included are a rectangular metal support stand, a burette clamp to hold the condenser, and clamps to fasten the ring burner and burette clamp to the stand upright. Main advantage of the special metal still and ring burner system is the burner can be moved up and down on the still while testing materials that solidify. Gas and air to the burner are regulated by an integral Fletcher attachment. Est. Ship Wt.: 20lb （9kg）.
