Manish engineering company offers the c 9500 series microprocessor multi-scale digital pressure meters and calibrators with flexibility and performance. These easy to use meters are available in a wide range of scale selection such as psi, mbar, in h2o, in hg, mm hg, torr, pa , kpa, mm h2o, cm h2o, kg.Cm². Each model has a carefully selected measurement range and can measure positive and negative [vacuum] gauge or differential pressures. These measurements include maximum and minimum readings held on display in any available scale, adjustable zero value to compensate for ambient temperature fluctuations by the user and selectable average reading to provide a further aid to accuracy by filtering out transient readings to give a stable readings. Additionally the pressure gauge along with test kit [hand pumps, etc] is an ideal portable pressure calibrator. Advantages: simplicity of use and excellent performance in terms of accuracy, resolution and linearity; high accuracy of ± 0.2 percent of full scale; due to its electronic sensor no tubes with liquid is required; digital display is easy to read and eliminates manual error; and also available in intrinsically safe models.
