Description

The DV series digital viscometer adopts the advanced micro computer driving technology, imported step motor, LCD backlight display, has the function of program setup, automatic control, features stable rotation speed, high accuracy, easy operation, fault alarming. This viscometer passed the full scale, linearity calibrations with standard silicon oil via PC interface, thus guaranteed the high sensitivity, accuracy, high repeatability, it’s kind of advanced viscometer in lab.

Features

1. Large LCD backlight display, English display, can indicate the rotor number, rotation speed, viscosity, torque, sample temperature etc.

2. Auto scan function, can advise the best matching of rotor and rotation, thus guarantee high test accuracy

3. Can use multi kinds of rotor: (1#,2#,3#,4#); small quantity adapter(21#,27#,28#,29#) as well as the 0# rotor for ultralow viscosity measurement

4. More advanced accuracy calibration technology, passed the full scale, linearity calibrations with standard silicon oil, thus guaranteed the high sensitivity, accuracy, high repeatability.

5. Has over range prompt function

6. Can select the temperature measuring probe, real time measure the sample temperature

7. Equipped with RS232 (or optional USB2.0) interface, connect with computer

8. Equipped with data processing software, real time record the relative change of viscosity along with the shear rate, time, temperature change, thus provide sufficient method to learn the non-Newton liquid viscosity characteristics

Full automatic Platinum Automatic Surface Tensiometer/ Interfacial Tensiometer

Full automatic Platinum Automatic Surface Tensiometer/ Interfacial Tensiometer

Full automatic Platinum Automatic Surface Tensiometer/ Interfacial Tensiometer

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

1. Both Pt board and Pt ring two methods are to be used

2. When using Pt board test, the displayed value is the surface tension value;

3. 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

4. Pt ring size: wire radius 0.185mm, ring radius is 9.55mm, ring circle length is 60mm;

5. When using Pt ring test method, it meets the below standards:

6. 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.

7. Full automatic measurement, avoid human error;

8. Full scale automatic calibration, good repeatability

9. Full scale onekey reset, stabile zero point no drift

10. Independent work, no need any other auxiliary device

11. 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)

12. When using Pt board test method, can automatically test the surface tension of middle or high viscosity liquid sample

13. Attached multi kinds of temperature control parts, meet different test requirements

14. Can supply tailor made as per customer requirements
