Standards: GB/T 22237-2008, JB/T 9388-2002, JB/T 18396-2001, SH/T 1156-95, GB/T 6541 – 86, ISO 1409-1995, ISO 6295-1983, GB/T 5549(ISO304-1985), ISO14090-82, ASTM D1417,EN14370,ZB2025-93, GB2960-82,GB6541-86 6.
Features
- Both Pt board and Pt ring two methods are to be used
- When using Pt board test, the displayed value is the surface tension value
- When using Pt ring test method, the indicating value auto lock the sample max force value, then the software will calculate the surface tension value
- Pt ring size: wire radius 0.185mm, ring radius is 9.55mm, ring circle length is 60mm
- When using Pt ring test method, it meets the below standards: GB/T 22237-2008 JB/T 9388 – 2002 JB/T 18396-2001 SH/T 1156-95 GB/T 6541 – 86 ISO 1409-1995 ISO 6295-1983 GB/T 5549(ISO304-1985), ISO14090-82, ASTM D1417,EN14370,ZB2025-93,GB2960-82,GB6541-86 6.
- Full automatic measurement, avoid human error
- Full scale automatic calibration, good repeatability
- Full scale onekey reset, stabile zero point no drift
- Independent work, no need any other auxiliary device
- When using Pt board, can measure the liquid surface tension or interfacial tension, for those samples that including surfactant or volatile substance, the surface tension will vary by time, this function is much more practical( the software can real time display the test curve, can obtain the tension vary detailed status)
- When using Pt board test method, can automatically test the surface tension of middle or high viscosity liquid sample
- Attached multi kinds of temperature control parts, meet different test requirements
- Can supply tailor made as per customer requirements
