Senva TGM-A4X-A : Metal Wall Mount R410A Refrigerant Sensor/Controller, 0-10V, 0-5V, 1-5V and 4-20mA Selectable Output, LCD Display, 7-Year Warranty

The Senva TGM-A4X-A is a wall-mounted sensor/controller that detects refrigerant leaks (including R410A, R134A, and others) in mechanical rooms. It features an LCD display, alarms occupants of high gas levels, and can directly control exhaust fans. It's pre-calibrated for R410A, offers multiple output options, and boasts a 7-year warranty.

Applications

  • Refrigerant leak detection in mechanical rooms
  • Pre-calibrated for R410A and also senses refrigerant including R134A, R410A, R407C, R404A, R22, R123
  • Monitor multiple gases with one mounted unit
  • Alert occupants of elevated gas levels
  • Directly control exhaust fans
