JB DMG2-8 2-Valve Digital Manifold, Monitor (diagonal): 4 1/3” / 11cm, Pressure measurement range: -14.5 to 870 psi, Precision (at 71.6°F):+/- 0.5% fs, Temperature measurement range:-58°F – 392°F, Working temperature:14°F – 122°F

The latest addition to the JB manifold line-up, the 2-Valve DMG2 digital manifold stands out from the competition with a large, easy to read back-lit screen with intuitive buttons that make getting the job done even easier. The DMG2 is stored with over 80 refrigerants, simultaneous calculates superheat and subcool, and features a robust transducer that is as reliable as a traditional manifold.

  • Its ergonomic design features a soft grip protective overmold with slip-proof notched knobs and a convenient hook to hang your manifold in tight spaces.
  • It includes a rugged carrying case and heavy duty clamps.
  • Preprogrammed with 80+ refrigerants.
  • Simultaneous calculation of superheat and subcool.
  • Robust transducer design.
  • Sturdy body designed for resiliency.
  • Heavy duty K-TYPE Thermal Couples included.
  • Simple and Accessible data display.
