Features and Benefits:
- Competitively priced
- Built-in self-diagnostics
- Easy to read, large LED display
- Four process relays with individually assignable set points
- Analog outputs for each sensor
- Excellent customer support
The Televac® MC300 vacuum controller controls up to two Televac® thermocouple gauges or convection gauges and an optional cold cathode gauge or mini BA hot ion high vacuum gauge. It features a 0 to 10 V DC analog output for each vacuum gauge, 4 relay set points for process control, and large, bright LED display, making it easy to read from a distance.
Note: sensors and cables are not included and must be ordered separately.
