Overheat Protection
: Room temperature to 399°C
: Proportional-integration type of zero cross
switching system
: ±0.1°C
: When the temperatures of the column
oven and the injection port/detector have
reached the set points, the respective
READY lamps are lit.
:
From room temperature to 350°C in 13 minutes.
: From 350°C to 100°C in 3.5 minutes.
: Stainless steel: 6m x 2
Glass: 5.4m x 2
: Two-stage protection:
(1) If the temperature exceeds the
programmed (preset) temperature by 50°C,
the heater will be automatically turned off.
(2) If the temperature reaches about 420°C,
the heater will be automatically turned off.
