Brief introduction: JML04S balance is based on the double drive membrane JML04LB film analyzer instrument, without tension membrane function, other functions are consistent with JML04LB film analyzer. Other liquid trough area can be customized. Features: 1. The operation process and data acquisition by PC computer and front single-chip microcomputer control, automation and intelligent, may make the artificial operation error to a minimum; 2. Key parts and components (including sensors), test data precision, good repeatability; 3. All Chinese operating software based on Windows WINDOW, user friendly interface, graphics printing, can store data can be secondary processing; 4. Liquid trough large surface area, high sensitivity, small leakage; 5. Can be automatically measuring the liquid surface tension. 6. Draw r - A and PI - A curve. 7. According to the r - A and PI - A set made membrane tension on the lower limit curve, sliding compression and expansion into A film. 8. Constant tension can be set, sliding barrier during tensile membrane move to maintain constant tension. 9. Thoughtful design can guarantee the equipment for conventional testing environment, and general configuration of the PC online work, smooth operation, little vibration, low noise Technical indicators: Surface tension measurement range: 0 mn/m - 150 mn/m Resolution: 0.05 mN/m Detection methods: hanging piece (WILHELMY TYPE) Mode of liquid trough: LANGMUIR Liquid tank material: all four fluorine material The compression area: 90% Sliding BARRIER: LEAKPROOF or BARRIER Sliding speed: 0.48-97 - mm/min Power supply voltage: AC220 plus or minus 10 v Power frequency: 50 hz Most consumed power: 150 w Working temperature: room temperature, can be an external waterbath Working humidity: 30% ~ 85% relative humidity
