JTZSE4 Digital Control Switch for Non-Corrosive Gases

The JTZSE4 Digital Control Switch is a popular standard model for use with non-corrosive gases [compound and low pressure]. It is a compact multi-purpose compound pressure gauge specifically designed to cover negative to normal pressure. A rear mount bracket option is available.

Features

  • Full 3-digit red LED display – gives a clear indication even in low light locations
  • Proven IP65 grade gauge body is suitable for industrial installations
  • Small, space-saving 30mm square face design
  • 2-point switch output with a total of eight operation modes possible
  • Analog output 1-5V in addition to the 2-point switch output
  • 8 different pressure units are available for selection
