Descrizione
Overviews
Le forze intermolecolari formano la tensione di interfaccia e la tensione superficiale dei liquidi. Il valore della tensione riflette le proprietà fisiche e chimiche e la struttura del materiale, che è uno dei più importanti per l'ispezione della qualità del prodotto.
Surface Tension Tester is used to test various liquid surface tension and interface tension based on the ring method that is simple and high accurate , which is widely applied on electric, petroleum, chemical,medicine, food and teaching filed.
Caratteristica
- Adopts unique and quick electromagnetic balance sensor for improving the measurement accuracy and linearity.
- Real-time indicates equivalent tension value and current weight .
- Only uses one point calibration to solve the problem of previous sensor that needs multi-points calibration. It is no need to use zero potentiometer and full range potentiometer.
- Integrated temperature detection circuit and auto temperature compensation of measurement result.
- 240X128 lattice LCD screen. No marked button has the function of screen protection.
- Built-in high speed thermal micro-printer to print out quickly . It has the function of off-line printer.
- Equips with RC232 interface , it can connect with computer to deal with measurement data .
