Components:
Standard configuration：Capillary with surface tension scale (2 or 4 pcs), Teflon dish, dropper head, instruction manual, Dedicated case
Technical data：
Scale range：0 ～ 80 mN/m
Resolution：1 mN/m
Quality：
The accuracy of the capillary rise method mainly depends on the quality and processing accuracy of the capillary. Only carefully selected and processed capillaries are used for products.
Feature：
Thanks to our inorganic material basis lyophilic coating, which is produced with highly developed sol-gel synthesis method, and our careful coating work, Surfgauge has overcome 2 main problems of complete wetting of samples and clearing of inner wall of the capillary. These 2 problems prevented the capirally rise method from being comercialised.

FAQ：
Q:
What is the accuracy?
A:
The accuracy mainly depends on the tolerance of inner diameter of the capillary. We carefully select only the capillaries which keep the accurate within +-3%.
Q:
What is the effect of viscosity?
A:
Basically, as long as the tested fluid has no yield stress it can be measured. But the greater the viscosity is, the longer the rising time becomes.
Q:
How does the inclination of the capillary during measurement affect the measurement results??
A:
No effect unless tilted beyond viewable level.

Q:
How to convert mN/m to dyne/cm?
A:
Both of the read values in mN/m and dyne/cm are the same. N (Newton) is now used as SI (International System of Units).
Q:
Measured value seems higher or lower.
A:
a) Correction for fluid density is required according to following equation:
surface tension = read value × density
b) Be careful not to leave any residue such as cleaning solution or previously measured liquid.
c) Be careful not to contact any contaminants, directly or indirectly, with the sample, including the sample container and the parts that come into contact with the capillary.
Especially in the case of water-based solution, even a slight amount of sebum greatly reduces the surface tension.
d) High surface tension tends not to reach proper height if inside the capillary completely dried. Please try pre-wetting according to the instruction manual.
Q:
Any attension for maintenace?
A:
Do not leave the capillary with tested fluid remaining inside the capillary. It or its precipitate tend to strongly bond to interior of the capillary as time passes. After using, rinse the tested fluid off under running water first and then remove the remaining water inside with acetone.
Q:
What are recommended washings?
A:
Basically, acetone and benzene. Also, alkaline cleaner solution can be used for strong contamination, but please note that its pH should be under 10.0 and below 50 dgrees. Proper washings for your samples also can be used as long as they doesn't damage glass.
A:
OK to use an ultrasonic washing machine?
Q:
Yes, but please do not avoid lengthy washing with it.
Components：
Standard configuration：Display and control box(standard or WiFi), sensor stick(Type-L for low vicosity or Type-H for high viscosity), instruction manual
Option/accessory：Calibration tool, carrying case
*WiFi compatible model includes the browser-based loggking software
Technical data：
Measuring force：40 ～ 1600 mN
Viscosity range(approx.)：50 ～ 1000 mPa・s(Type-L), 500 ～ 10000 mPa・s(Type-H)
Measuring temperature： 0 ～ 100 ℃
Feature：
We do blending, mixing, foaming, beating, kneading, etc. in our daily lives. By feeling the flowing resistance we determine how the material is easy to mix or guess the changes of material state. The flowing resistance we feel does not come from only viscosity but also certain or uncertain other factors like postural change, stability, distortion or human habit. The SVE-1 measures "real" flowing resistance force and evaluating viscous of the fluid in human stirring motion.。
WiFi：
The SVE-1 equips WiFi module(optional), which is capable of directly transmitting to your tablets/PCs to browse, log and visualize the data.

FAQ：
Q:
How to select Type-L and Tyep-H?
A:
Tyep-L is for lower viscosity and Type-H is for higher viscosity. Estimated suitable viscosity ranges are
Tyep-L： 50 ～ 1000 mPa・s
Tyep-H： 500 ～ 10000 mPa・s
Q:
What can I do with the WiFi module?
A:
By directly communicating with your PC or tablet device equipped with WiFi, the logger software which is not needed to be installed starts on the browser. It is possible to visualize data and record values on the data sheet.

Feature：
This is a surface tension meter based on the du Nouy method, which is one of the most typical surface tension measurement methods. By simply pulling the platinum ring away from the liquid surface, accurate surface tension values are automatically measured. The DRT-2 supports sample density correction.

FAQ：
Components:：
Standard configuration：Main device, 4 syringes, 4 needles(stainless steel), Power supply, Instruction manual
Option/accessory：Fluorine resin needle, Carrying case
Technical data：
Displayed output：Surface tension[mN/m], Deinsity[g/cm^3], Dropping time[sec.]
Resolution：0.1 mN/m (surface tension), 0.1sec (dropping time)
Density correction setting range：0.60 ～ 1.80 g/cm^3
Dropping velosity：3 steps switching
Dimension：120(W) x 70(H) x 35(D) mm (without syringe)
Power supply：6V, 2A
Feature：
Due to the sensitivity of surface tension measurements, it was difficult to perform immediate measurements on-site because it required measurements in a laboratory after sampling, and the need for instrument cleaning. However, the ADC-1, a handheld device, can be used on the spot and is compatible with disposable syringes. After measurement, the syringe can be discarded or cleaned later, eliminating the need to bring it to the laboratory or perform measurements while cleaning.
It is a surface tension meter with a focus on on-site measurements, allowing for measurement of surface tension at the actual location.

FAQ：
Q:
How many drops for measurement?
A:
A minimum of 10 drops or approximately 20 drops is recommended as a guideline
Q:
Is it possible to use my own syringe?
A:
A syringe with a diameter that can be securely attached to the holder can be used. Please be cautious when using syringes of the piston type, such as the rubber piston, as there is a concern about contamination from lubricants applied to the piston, which may affect the sample. We recommend using all-plastic type syringes.
Q:
What is the recommended guideline for setting the drop rate?
A:
In the following cases, measurements are performed using a low-speed setting:
・The drop interval is short (using a fine needle, measuring low surface tension liquids)
・The sample contains surfactants (to avoid the influence of dynamic surface tension)
・Measuring viscous liquids.
Q:
The sample wets up on the needle.
A:
Please use a fluororesin needle (optional) in such cases.
