Lighted wave graphs (on all models except 1L and Triad) are visible from a distance and indicate when temperature and vacuum levels are right for adding samples. Vacuum control valve, (on all models except 1L), maintains setpoint vacuum level. Moisture sensor, (on all models except 1L), protects the system from oil backstreaming during power outages. All models require a rotary vane vacuum pump for operation: - Models 1L to 4.5L, require a pump with at least 86L/min displacement. - Models with 6L to 18L require a pump with at least 144L/min displacement.
