 Cryogenic Temperature Instrument Selection Guide |
|
|
|
|
|
Features
- Resistance measurement ranges from 2 mW to 2 MW
- 21 excitation levels from 3.16 pA to 31.6 mA
- Displays real-time sensor excitation power
- One sensor input (up to 8 or 16 with one of the three scanners offered)
- PID temperature control
- IEEE-488 and RS-232C interfaces, alarms, relays, and analog outputs
- Patented current source preserves common mode noise rejection and optically isolated measurement electronics eliminates the potential for ground loops
