Product Description:


yarn tension meter
1.portable,compact,mechanical tension measuring device.
2.dependence and accuracy.

1.Brief introduction of instrument:

Measuring apparatus this adopt accurate transmission device that develop newly,can

make the instrument in measurement steady accurate reading the necessary data fast.

this instrumental error values in positive and negative 1 Newton scope.

In the screen printing of network monitoring silk screen version of the manufacture and

use of the process Screen tension values may also be used for other needs Plane tension

measurement products.


1.Before using please put the tension meter on the glass and turn round the dial to make the pointer return to zero.

2.Flick the silk screen during measuring, the indication when the pointer stopped is the tension of the silk screen.

3.Tension meter is precision meter, fall and touch is forbidden, be careful during using.

4.Tension meter has been tested precisely when leave the factory, dismounting alone is

not allowed.

5. Can’t touch the bottom side contactor by hand, put the machine vertically without using.

6. The Newton indication is the indication of the tension’s contactor, the error is +0.5N.

7. The indication of the second circle is the measured value during measuring.


NR110 digital colorimeter electronic test instruments is under warranty for 12 months from the purchase

date. Customers must provide warranty card and valid proof of purchase.

Q:What is the effect of the centrifugal fan on the wind pressure?
With the export of cross-sectional area continues to increase, air volume also increased, the pressure decreased.
Q:How does the material of the high temperature fan choose?
In the manufacturing process is strictly prohibited the use of mezzanine, heavy leather and other defects in the material, the material on the outer surface of the material shall not have obvious scratches, aluminum local scratch depth of not more than 0.3mm,
Q:What is the difference between an axial fan and a DC fan?
Axial fans are often used in situations where the flow rate is high and the pressure is low. The axial fan is fixed and moves the air. Axial fans are mainly composed of fan impellers and housings. The structure is simple but the data is very high.
Q:What is the use of two-speed fan?
As the basement by the underground conditions and space constraints, to meet the air volume and wind pressure and other parameters of the conditions, the fire exhaust system and the usual ventilation can be combined
Q:How is the suction of the centrifugal fan measured?
In a single-stage centrifugal fan, the gas enters the impeller from the axial direction, the gas flows into the radial direction when passing through the impeller, and then enters the diffuser
Q:How to distinguish the high, medium and low pressure of the fan?
N = 60-30 for the medium pressure fan; n = 30-5 for the high pressure fan, the specific speed is calculated by the calculation.
Q:How to deal with axial fan noise?
The impeller is an integral part of every type of fan that can not be left, and it produces very noticeable noise at high speeds and low loads. This noise is mainly due to the rotation of the blade around the blade and the design of the blade Uneven flow of the interaction caused by the noise. This is just one of the reasons
Q:What is the role of ion fan?
General ion fan can be divided into desktop ion fan, horizontal ion fan, hanging ion fan, micro ion fan.
Q:What is the difference between a jet fan and an axial fan?
When the fan is running, through the blade hydraulic adjustment device, can adjust the blade installation angle, and maintain a certain angle, so that it works in the variable conditions still have a high efficiency.
Q:What is the working principle of the suction blower?
And because the blade is rigid, the partially compressed air can only move away from the direction of the blade, so that the air is moved to form the effect of blowing
