ZL-A series of Surface Tension Tester
Physical method is applied to measure the tension of liquid.This
kind of tensiometer is widely used in science institutes and
universities as well as water and power sectors.
1.Using advanced electromagnetic balance force sensor, with high
precision, high repeatability characteristics.
2.5 inches wide touch screen control, current environment
temperature, current tension, peak tension, equivalent tension and
other information integration display, operation is very simple.
3.Design platinum plate, platinum ring at the same time two test
methods, can choose one of them, can also choose two at the same
4.Fully automatic operation, eliminate all human error. Automatic
lock liquid interface, display tension curve, automatic lock peak
tension, without any conversion, direct screen display tension
value. Automatic stop measurement, no manual operation, reduce
5.Full range automatic calibration, weight calibration support
weights, distilled water and anhydrous ethanol calibration
6.The sample table automatically rises and falls with no noise. The
rising and falling speed can be adjusted at the same speed through
the touch screen (1-300mm/min).
7.Convenient lifting bracket for platinum plate and platinum ring,
which is very easy for users to unload, and the accuracy of force
value can be calibrated by standard weight at any time.
8.One-key peeling function, the number does not jump, zero drift.
9.Environmental temperature automatic compensation, on the basis of
water, ethanol, automatic conversion sample 20 ° C under tension
10.Configure data acquisition software for all Windows systems (WIN
7,WIN 8,WIN 10,WIN XP).
11.Meet but not limited to the following standards:
GB/T6541-86 ISO1409-1995 GB/T22237-2008 SH/T1156-95
ISO6295-1983 JB/T18396-2001 GB/T5549(ISO 304-1985)
12.Have the patent certificate of the instrument
