A rugged portable vacuum gauge for processing applications that pairs unparalleled vacuum measurement with the Agilent 536 sensor that has an integrated baffle which provides protection and helps reduce risk of sensor failure

Numeric & Graphical Displays

  • See vacuum readings in either numbers or easy-to-read graphs
  • Has 12 measurement units for implementation in almost any vacuum application
  • Torr, mbar, bar, kPa, inches of Hg, mm Hg, millitorr, microns, inches of water, PSI, Pa

Calibrated & Precise

  • Delivered pre-calibrated with Agilent/ Varian 536 thermocouple sensor under actual vacuum against the NIST standard. Note: NIST certification sent with the gauge is an available option here
  • The 536 all stainless steel sensor with baffle has extended sensor life in the presence of condensable gases and improved performance at higher pressures
  • Vacuum Interface: KF25 or NPT or KF16 | optional purchase with the Stainless NW25 Wing Clamp and Centering Ring
  • Wetted materials: 304L Stainless steel, glass, Type P thermocouple

Extended Battery Lifespan

  • Portable | Solid state electronics built into a handheld gauge that operates using AA batteries that lasts up to 70 hours
  • In-lab use | Power gauge using the integrated Micro-USB port for long-term use without the need to change batteries

Ideal Vacuum Gauge for Processing Applications

  • Laboratory, freeze drying, low pressure distillations, foreline monitoring, Schlenk lines performance, and transformer dry-out
  • Or any application with higher levels of condensables where sensor failure is more likely
