Constant temperature humidity test box common use questions

Question 1: users who use the constant temperature and humidity test chamber for the first time may encounter this situation. The humidity suddenly shows 100% in the test process, but they do not know what causes it. Etapa 1: Check whether the wet bulb gauze is hanging on the humidity sensor.The sensor near the sink is the humidity sensor. The gauze should be hung on the humidity sensor and cover the temperature sensing part of the sensor.There are a few...

Care este motivul defecțiunii pulverizatorului în camera de testare cu pulverizare de sare

Camera de testare cu pulverizare cu sare poate testa rezistența la coroziune a unor mărfuri conform inspecției materiilor prime, corrosion resistance and corrosion working ability, as well as the processing quality of similar protective layer.The test chamber is suitable for parts, electronic components and metal composite materials.And corrosion resistance and erosion tests of industrial products.Next, let's look at the reason why the sprayer of the salt spray test chamber fails. 1. Check whether the switching power supply is plugged in,...

Demand and test method analysis of tensile force and standard distance of rubber tensile testing machine

The tensile strength and calibration distance of rubber tension testing machine are two very important parameters in the process of using, tensile strength and calibration distance change, so the demand for these two parameters is very high, they directly determine the success or failure of the tension testing machine experiment and the quality, the following summary of the following requirements for tensile strength and calibration distance: 1. Equipment to accurately depict stress-strain curves There is a close relation between the tension...

Sampling method and operating procedure of rubber material in tensile test

Rubber products have now become essential daily necessities in our daily life, such as tires, rubber pipes, benzi transportoare, sealing rings and so on.Before these rubber materials can be made into rubber products, we will do a series of tests to prove that it is qualified before it can be used for production.The rubber tensile test is one of the comprehensive physical and mechanical properties test items.Here, Suzhou Ligao will teach you the sampling method and operation procedure of...

How does the tensile machine and the tension testing machine jig affect the sample slipping?

Tensile machine, tensile testing machine is widely used in all kinds of hardware, metal, rubber plastic, footwear, Piele, clothing, textile, insulation, sârmă, cable, terminal...And all kinds of materials, test its stretch, rupere, pieliță, comprimare, bending and other materials development, inspection test, the function of its complete, widely used.But we in the use of tensile testing machine for testing sample inspection during mechanical testing, tensile testing machine clamp has often found sliding surface, and use the longer, the sliding surface,...

Calibrarea mașinii de tensiune computerizată, calibrarea mașinii de tensionare software de calculator, calibrarea mașinii de testare a tensiunii

Calibrarea mașinii de tensiune pe computer, software de calculator calibrarea mașinii de tensionare, Senzor de putere interfață de calibrare a mașinii de testare a tensiunii, senzor de călătorie, rubber extenometer, metal extenometer and system Settings five TAB, select each TAB for the corresponding sensor calibration or setting. 1. Calibrate the force sensor Select the force sensor TAB, as shown in Figure 6.There are four force sensor channels shown on the left: "50kg", "0.0kg", "0.0kg" și "0.0kg". The calibration process is as follows: 1. Plug in the force sensor to be calibrated, ca...

What is yield strength, tensile strength/yield strength formula

Tensile machine, mașină de încercare la tracțiune, universal material testing machine yield strength refers to the material tensile stress-strain curve yield strength Is the critical stress value of the material yield. (1) For materials with obvious yield phenomenon, the yield strength is the stress at the yield point (yield value);(2) For materials whose yield phenomenon is not obvious, the stress when the limit deviation of the stress-strain linear relationship reaches a specified value (usually 0.2% permanent deformation).It is usually used as the evaluation index...
