KJLC® 972 Series

Note KJLC no longer offers the 972 combination gauge. Please consider the KJLC Cold Cathode / Pirani as a possible alternative. Please contact gauging@lesker.com for further details or technical support.

Features

  • Single transducer provides a wide measurement range of 10-8 Torr to atmosphere, eliminating the need for multiple vacuum gauges
  • The MEMS based MicroPirani™ sensors allows low auto cold cathode turn-on pressure (user programmable from 2x10-4 to 1x10-3 Torr) for enhanced reliability
  • Includes both analog and digital communication for ease of operation
  • MicroPirani™ is automatically zeroed during pump down cycle for improved accuracy
  • Mountable in any orientation
  • Simplified interface via a single smoothed analog output that combines the individual vacuum sensor measurements
  • Alternate analog output and electrical connectors available to match other vendors' vacuum gauges and facilitate an easy upgrade
  • Can be used with the PDR900 Vacuum Gauge Controller and Display for Series 900 Transducers for easy set up
  • RoHS and CE Compliant
