Model: HJBM-1 (common type) HJBM-2 (Scientific Research) ■ Instrument features ● with a 5-inch color LCD display, user-friendly interface, through virtual touch key operation ● integrated design, compact and exquisite structure ● Built thicken plexiglass water bath, precise temperature control, rapid heating. Temperature control parameters by a touch-screen virtual keyboard, easy to operate. Stirring motor speed control via touch-screen buttons. Water bath heater rod power is small, multiple instruments simultaneously will not exceed the power load. ● capillary height adjustable, precise control of capillary and page tangent ● Built precision micro booster pump, controlled by step-down switching valve, high-intensity explosion-proof buffer tank. Precision trimming by capillary pressure valve adjustment, convenient and accurate operation (with 32 pressure calibration points) ● precision pressure sensor, responsive and accurate ● pressure recording function, recording automatically determine the peak pressure, the peak time of recording data and appear in color LCD indicators on the instrument panel ■ Temperature resolution 0.005 ℃ (Normal) 0.001 ℃ (Scientific Research) temperature range of room temperature ~ 100.00 ℃ temperature fluctuation pressure resolution 1Pa 0.005 ℃ (Normal) 0.001 ℃ (research-based) Pressure Accuracy 0.2 % FS timer range 0.0s ~ 999min59.9s, precision: 0.1s heating power 250W glassware sample tube, capillary capillary height adjustment range 0 ~ 5mm, 0.01mm precision micro-pressure adjustment pump adjustment range -10.000 KPa ~ + 10.000 KPa ( Normal) -15.000 KPa ~ + 15.000 KPa (Scientific Research) Adjustable sensitivity: ± 1Pa / s Pressure measuring range -10.000 kPa ~ + 10.000 kPa, built-in 32-point pressure calibration automatically determine the maximum and minimum pressure, automatic timing and display the latest 5 set of pressure, time
