Which is a good desktop hot wire tester

Hot wire tester (remote control)

It is a device used to test the flammability and flame resistance of materials or products under the action of high-temperature hot wires, widely used in industries such as electrical, electronic, and building materials. Its remote control function can improve the safety and convenience of operation. Here is the relevant introduction:

working principle

By heating a specified size and shape of hot wire to a specific temperature (such as 550 ℃, 750 ℃, 960 ℃, etc.) and applying a certain pressure and time to the sample, the combustion behavior of the sample is observed, such as whether it ignites, the duration of the flame, and whether there are droplets, to evaluate the flame retardant performance of the sample.

structural composition

•Heating wire component: made of nickel chromium alloy wire, it is the core component of the instrument, which can be heated to the desired temperature through heating elements and precisely controlled and monitored by a temperature control system.

•Sample fixture: used to fix the sample, ensuring that the sample remains stable during the testing process and maintains the correct relative position with the hot wire.

•Remote control system: equipped with a wireless remote control, the instrument can be operated from a certain distance, such as starting and stopping the test, adjusting the temperature of the heating wire, applying time, etc., to avoid close contact between operators and high-temperature components during the test process and improve safety.

•Temperature measurement and control system: high-precision temperature sensors (such as thermocouples) are used to measure the temperature of the heating wire in real time, and the temperature is controlled within the specified error range through the control system to ensure the consistency of the test conditions.

•Combustion chamber: provides a relatively enclosed space for testing, preventing flames, smoke, and other substances generated during the testing process from affecting the surrounding environment, while also facilitating observation of the combustion situation of the sample.

1、 Heating wire temperature: adjustable within the range of room temperature to 1000 ℃.

2、 The temperature measuring thermocouple adopts nickel chromium and nickel aluminum (K) type armored filament thermocouples with a nominal diameter of Ø 1.0mm.

Hot wire tester (remote control)Main technical parameters

•The temperature range of the heating wire is generally between 500 ℃ and 1000 ℃, which can be adjusted according to different testing standards and requirements. The temperature accuracy is usually ± 5 ℃.

•Heating wire application time: can be set arbitrarily within the range of 0-99.9s, with an accuracy of ± 0.1s.

•Sample size: It can adapt to samples of different sizes. Common sample fixtures can fix sample sizes of length x width ≤ 150mm x 150mm and thickness ≤ 60mm.
