Introduction: HJBM-1 surface tension test device measures the surface tension data of the solution at different temperatures by the maximum bubble method; Built-in constant temperature water bath, automatic magnetic stirring, micro pressure pump, pressure trim valve, pressure sensor, etc., integrated design, printed equipment on the top of the chassis The internal structure shows. Features: 1. Determination of the surface tension data of the solution at different temperatures by the maximum bubble method; 2. Built-in constant temperature water bath, automatic magnetic stirring, micro-pressure pump, pressure trimming valve, pressure sensor, etc., integrated design, the top of the chassis is printed with a schematic diagram of the internal structure of the device, to facilitate teachers to explain the principle and operation of the device; 3. Equipped with 5-inch color LCD touch display, real-time display of real-time temperature, real-time pressure and other data, directly through the touch screen keyboard to enter the target temperature value, easy to operate; 4. The constant temperature water bath adopts a new cylindrical plexiglass water tank, beautiful appearance, good mixing effect, the heating rod and temperature sensor are fixed at the bottom of the water tank to avoid the damage during the operation process of the student. The upper part of the water tank does not have any interference operation components, and the design is reasonable. ; 5. The heating rod adopts low-power design, avoiding the power load of the lab caused by the high-power heating rod is too large, and the temperature sensor is made of high-quality stainless steel armored Pt100, with accurate temperature measurement; 6. Automatic magnetic stirring can be set stirring speed, stirring rotor with PTFE rotor; 7. The pressure recording function can automatically determine the pressure peak during the bubbling process and display the peak data on the LCD screen in a fixed manner to assist student records. Technical Parameters: Instrument Name: HJBM-1 Normal Type HJBM-2 Scientific Type Bath temperature range: Room temperature ~100.0°C Water bath temperature resolution: 0.1°C 0.01°C Water bath temperature control accuracy: ±0.2°C ±0.05°C Water Bath Heater: 250W stainless steel corrosion resistant heating rod Pressure measurement range: -10kPa~10kPa -15kPa~15kPa Pressure Resolution: 1Pa Pressure accuracy: 0.2%F.S. Pressure calibration points: 10 32 Timer function: 0~100min, accuracy: 0.1s
