Sweating Guarded Hotplate TF129

Rated 4.75 out of 5 based on 4 customer ratings
(4 customer reviews)

Sweating Guarded Hotplate is the most professional, stable and advanced Thermal and Evaporative Resistance test instrument in the world.

Application

Sweating Guarded Hotplate is the most professional, stable and advanced Thermal and Evaporative Resistance test instrument in the world.

Human skin simulation test plate, automatic water supply system, wind speed stabilization system, test host and climate chamber are completely separated design. Automatically adjust the height of the hotplate according to the thickness of the test sample, ensure the wind sensor is 15mm above the hotplate.

A Windows based software is offered. The main machine inside the chamber is connected with the software by Wi-Fi, so operators may control and monitor the testing in the office.

An advanced Temperature & Humidity Chamber is offered with the machine.

Why We Need the Thermal Resistance Test?

When people wearing clothes in cold or hot climates, the temperature of clothing, especially close-fitting, varies with the temperature of the skin. People should choose suitable clothes to ensure comfort, or at least in adverse weather conditions to protect the human body. The heat transfer property of fabric can ensure the comfort of clothing, for example, the clothing with high thermal resistance has a better function of preventing cold, while the clothes with low thermal resistance can give a cool feeling. Therefore, testing the thermal resistance of fabrics has an important reference for improving people’s clothing comfort.

Thermal Resistance Test Principle

The sweating guarded hot plate instrument produced by our company adopts the constant temperature method. Place the sample to be tested on an electric hot plate which has good thermal insulation at all the other surfaces. Transfer heat to an electric heating plate so that it reaches constant temperature state, and test the heat needed to maintain the constant temperature of the electric heating plate. This method has been adopted by ASTM as the standard number ASTM D1518.

Sweating Guarded Hot Plate Test Method

Assemble the instrument, install SGHP software according to instructions, connect with thermal resistance instrument through network signal, and prepare for the test.

The RCT0 test is used to express the basic parameter of a machine. The value of Rct0 will be used to calculate the final RCT value of a sample. Rct0 test should be done when the machine stopped for a long time or the environment changed great.

Cut the sample as 50 cm x 50 cm, and pretreat it according to the standard requirements. Place the treated sample on the surface of the test area. If the thickness of the sample is more than 1 mm, then adjust the height of the wind speed sensor so that the height between the sample and the sensor is about 15 mm. According to the standard requirements to set the temp and humidity and then start the test until the testing environment is stable. Record the test results and calculate the final RCT values of the sample.

Daily Maintenance

1 Keep the machine clean: Clean the surface of the test plate and the dust of the air of exhaust grid by using the towel.
2 If the Ret test is finished and another Ret test will be run in next day, then open the safety cover and open the door of the conditioning chamber, the water will be evaporated from inside of the machine, and prolong the service life of the machine.
3 If the conditioning chamber will not be used for a long time, please drain off the water of the conditioning chamber.

Q: Does the chamber have the option – control humidity?

A: No, it is not equipped with this option.

 

Q: At what humidity ranges is the machine able to run?

A: The machine is not equipped with control humidity, but Temperature & Humidity Chamber can meet your needs, with its humidity range of 25%~85% R.H.

 

Q: What advantages does the machine have?

A: 1. It can contact with WIFI.

  1. The thermal resistance and Temperature & Humidity Chamber can be used separately. And other suppliers combine the two machines into one. They must be used together.
    <start=”3″>
  2. Our Temperature & Humidity Chamber is made by a professional factory, which is more accurate. The ITS (Intertek testing service) bought this machine from a famous company, whose price is triple than ours. The test results from this machine are not precise because the machine is made by the company himself. Finally, he turned to us and bought a new one. We only do what we are good at.
