Manual Surface Tensiometer, 0-200mN/m, 0.02mN/m, Shanghai HengPing Instrument and meter Co.,Ltd. (CAT#: STEM-AI-0369-YJL)

Manual Surface Tensiometer, 0-200mN/m, 0.02mN/m, model BZY-4B is manufactured by Shanghai HengPing Instrument and meter Co.,Ltd. The main technical indicators of this table/interface tension instrument still meet the full -automatic basic standards. Except for the test platform of the instrument from automatic lifting to manual lifting (including fast and fine -tuning second gear), the test process is still automatic test. Calculation is calculated.And display.Under the premise of ensuring technical indicators, it is an economic practical product.

Measuring range: 0-200.0mN/m
Measurement accuracy: 0.02mN/m
Repeatability: ±0.03
Platform lifting distance (mm): fast 16, fine-tuning 18, fine-tuning scale 0.02 per grid
Signal output interface: RS232C
Dimensions(mm): 300×190×400(L×W×H)
Net weight (kg): 7
Synchronous curve software: Real-time curve software function: Connect the computer to display the real-time tension curve, move the mouse to any point on the curve, the tension value and time of the point will be displayed, and the test curve, data and time can be saved and queried. The vertical setting can realize the enlargement and reduction of the tension value curve, and the horizontal setting screen can be enlarged 1-10 times, and the data can be set according to the tension value of the measured liquid.

Compared with other surface tensiometers, BZY series manual surface tensiometers have the following advantages:
* The sensor is responsive, high precision, LCD display;
* Automatically read the surface tension balance value;
* There are two fast and fine-tuning gears for manual lifting, which is easy to operate;
* One-key reset;
* One-key calibration, with the standard weights attached, accurate and fast;
* The error caused by the instrument itself is small, and various errors in the measurement process are more effectively controlled;
* Using platinum plate method or platinum ring method, connected to computer, optional real-time curve software:
The rise or fall of tension over time due to the presence of surfactant can be clearly displayed.
It can display the curve and time of the liquid interface of two different densities from the lowest to the largest tension value, such as the oil/water interfacial tension value.
* Optional sample constant temperature cup, external constant temperature bath can control the temperature of the liquid to be measured.
* Easy to operate.
