VD8TC - Vacuum Tester / Data Logger for Thermocouple Sensors
25 mbar to 1.0 x 10-3 mbar (9999 mTorr to 1 mTorr)
The VD8TC compact vacuum tester is used for measuring total pressure in combination with the following types of thermocouple sensors
Teledyne Hastings DV4, Teledyne Hastings DV6 or Televac 2A.
Benefits
- Automatic detection of the sensor type (pat. pend.)
- Steady measurements within a few seconds
- ADiscs used in conjunction with the VD8TC give each thermocouple sensor a unique electronic identity. For the first time, the user has a way to automatically record and maintain measurement data (pat. pend.)
- Storage of measurement parameters by push of a button: sensor ID, date, time and pressure values
- Long battery life
- USB interface for data transfer to a PC
- A user defined configuration can be done at the instrument or when using a PC operating VacuGraphTM software, connected to the VD8TC with a USB cable
- The VD8TC includes a rugged protective carry case and battery
Typical Applications
- Vacuum jacketed cryogenic vessels and delivery lines
- Air-conditioning and refrigeration system manufacture and service
- Monitoring house vacuum systems and lines
- In-process testing during vacuum system manufacture
- Vacuum pump repair and service
- Leak testing
