二、性能及特點 1、本儀器溫度計夾裝在立柱上,可上下調節高度,以保證溫度計的水銀球位于內坩堝。 2、氣體導管內孔表面清潔,通過調節,能使點火器的火焰長度穩定為3~4mm。 3、本儀器加熱爐采用電子固態調壓方式,0~220V電壓任意調節,數字顯示工作電流電壓,顯示直觀。由一個電位器控制,可無級調節加熱功率,操作維修十分方便,從而保證試樣的升溫速度達到標準要求。 JSH3801 petroleum product opening flash point and ignition point tester
This instrument is suitable for determining the flash point and ignition point of lubricating oil and dark-colored petroleum products, in accordance with GB/T267 standard.
1. The thermometer of this instrument is clamped on the column, and the height can be adjusted up and down to ensure that the mercury ball of the thermometer is in the center of the crucible.
2. The surface of the inner hole of the gas conduit is cleaned. Through adjustment, the flame length of the igniter can be stabilized to 3 ~ 4mm.
3. The heating furnace of this instrument adopts electronic solid-state voltage regulation mode, 0 ~ 220V voltage is adjusted arbitrarily, digital display of working current and voltage is intuitive. Controlled by a potentiometer, the heating power can be adjusted stepless, which is very convenient for operation and maintenance, so as to ensure that the heating speed of the sample can meet the standard requirements.
