  • Guide to Minimizing User Errors in pH Measurements
    concentration. Error is different for almost every acid Error may be as high as 0.5 pH There is no clear theoretical explanation and no clear relationship to pH glass compositions Magnitude of error can be determined by using solutions of known concentration
  • Properties of 17-4 PH Stainless Steel Produced via Press and Sinter Route
    MPa, 87 KSI in tensile strength) and a moderate ductility, alloys from the precipitation strengthened family of stainless steels are often considered as potential candidates. The most popular alloy of this family is 17-4 PH. Full dense version of this alloy, produced via MIM route, has gained a high
  • Application Note - New USEPA Rules for Drinking Water - A Compliance Strategy (.pdf)
    be taken of the source water and the distributed water after flocculation/softening. The TOC removal requirements are based both on the TOC concentration and the alkalinity of the raw water and adjusted for alkalinity because the optimum pH for TOC removal is often below 6.0. Thus, high alkalinity
  • Delrin
    electrical insulating characteristics. Delrin is resilient and resists creep. It is also maintains natural lubricity at a wide end-use temperature range. The main property limitations are repeated use in steam or hot water, and exposure to strong acids or bases outside the pH range of 4-9.
  • Application of Pick-and-Hold Modules
    Geeplus's Pick & Hold Modules are designed to work with a wide range of different solenoids, and over a wide range of operating voltage. We recommend the use of a high source voltage to minimise electrical time constant, but modules will work down to 20v supply. Control inputs are opto-isolated so
  • The conversion
    and Kraft linerboard (KLB) on their three-ply KLB machine. The sizing philosophy on the machine has followed the traditional route of acid sizing. Sizing has been achieved with alum and a rosin emulsion size in the pH range of 4.5 to 5.0. There have been periods of excessive size usage and pH swings
  • Monitoring Water Quality Runoff From a Coalmine
    of the surrounding farming district. Therefore it was necessary to closely monitor the quality of water in the retaining dam across several key parameters including pH. Management began searching for a data logging solution with the versatility to connect to a wide range of sensors and capable
  • The conversion of a kraft linerboard machine
    the traditional route of acid sizing. Sizing has been achieved with alum and a rosin emulsion size in the pH range of 4.5 to 5.0. There have been periods of excessive size usage and pH swings with many of these relating to the white top liner makings. It has long been known that paper and board produced
