The lab heating board chooses what your zui values
The laboratory heating plate is made of aluminum plate with good thermal conductivity, which has the effect of safe heating and constant temperature control. The laboratory heating plate is widely used in the laboratory with high safety system, including fixed safety circuit, overheat display and error display. The laboratory heating plate can also be equipped with a contact electronic temperature sensor, which can achieve high precision temperature control effect. Functionality, safety and durability are the three main characteristics of laboratory heating plates.
Compared with general fuel heating, laboratory heating plate can obtain a higher temperature (such as arc heating, the temperature can reach more than 3000℃), easy to achieve automatic temperature control and remote control, car electric heating cup can keep a certain temperature distribution of the heated object. Electric heating can generate heat directly in the heated object, so the thermal efficiency is high and the heating rate is fast. According to the technical requirements of heating, uniform heating or partial heating (including surface heating) can be achieved. It is easy to achieve vacuum heating and control atmosphere heating. In the process of electric heating, there is little waste gas, residue and smoke, which can keep the heated object clean and do not pollute the environment. Therefore, laboratory heating plate is widely used in production, scientific research and testing. Electric heating is used especially in the manufacture of single crystal and transistor, mechanical parts and surface quenching, smelting of ferroalloy and manufacture of artificial graphite.
Face numerous laboratory heating plate brands on the market, all kinds of heating plate material and selection of parameters, how to choose and buy zui is suitable for the type of the heating plate, we want to make choice, first of all to understand well the meaning of the various parameters, manufacturer or instrument manufacturers to product labeling technology parameters, or complex refractory, or simple empty, these all have no relation, good you just focus on the following key parameters can be.
1. Temperature uniformity is an important parameter of heating plate zui. Temperature uniformity of heating plate refers to the uniformity of temperature distribution on the panel when the heating temperature is displayed to the set temperature, and the temperature difference between the high point of temperature zui and the low point of temperature zui.
2, the resolution, that is to read, that is to show you the temperature value to the decimal, is an important indicator to measure the display control ability of the heating plate, the general heating plate is 1, that is, the integer display, more precise degree can be up to 0.1.
3. Sensor temperature control refers to the control ability of the internal temperature control system of the heating plate. The error range when the heating plate reaches the set temperature is one of the important indexes to measure the heating system performance of the heating plate, just like the temperature uniformity of the heating plate.
