Specialized manufacturer of Digital Pressure Meters and Load Cells



Low Pressure Transmitter (Wetted Part: Equivalent to hastelloy C-22)
VAR3(G3) series
100kPa–700kPa abs

  • Adoption of hastelloy C-22 equivalent diaphragm offers high corrosion resistance.
  • Diaphragm structure enables high accuracy measurement even in lower pressure range. (Non Linearity: ±0.2%R.C.)
  • Gauge pressure reference and absolute pressure reference available.
Measured medium Water, oil, gases or other media that will not corrode SUS316L and Hastelloy C-22 equivalent.
Pressure Type Positive and absolute pressures can be measured.
Measured Range Can be specified within the range of 100 kPa to 700 kPa (Calibration: 50 to 700kPa) of rated capacity.
Specify more than 50% of rated capacity as the calibration range.
