CVM211 & CVM201 – Convection-Enhanced Pirani Gauge Controllers

Take your vacuum measurement to the next level with the CVM211 and CVM201, featuring convection-enhanced Pirani technology for superior accuracy across a wide pressure range.

Why Choose These Controllers?
✔ Extended Range – From atmosphere to 1.10 × 10⁻⁴ mBar
✔ Multi-Unit Readout – Pressure displayed in Torr, mBar, and kPa
✔ Better Than Thermocouple Gauges – Higher accuracy and improved low-pressure performance

Model Highlights:

• CVM211:
  • 1 SPDT setpoint relay for reliable control
• CVM201:
  • 2 SPDT relays
  • 1 linear and 1 log-linear analog output
  • RS485/RS232 serial communication (ASCII protocol) for easy integration

Setpoint Accuracy (N₂):
• 1.0 × 10⁻⁴ to 1.0 × 10⁻³ Torr: 0.1 mTorr resolution

Note: Power supply sold separately.

Perfect for industrial vacuum systems, laboratories, and R&D environments, these controllers deliver precision, flexibility, and connectivity.
