Muffle stove is widely used and easy to use

The wide use of muffle stoves:

1. Analytical Chemistry Industry: Sample processing as water quality analysis, environmental analysis and other fields. It can also be used for petroleum and its analysis.

2. Coal quality analysis: Used to determine moisture, ash, volatile matter, ash melting point analysis, ash component analysis, element analysis. It can also be used as a general ashing furnace.

3. Hot processing, cement, building materials industry, small workpiece hot processing or processing.

4. Pharmaceutical industry: used for drug testing, pretreatment of medical samples, etc.

Understand the following things, muffle furnace is relatively simple to use.

box type resistance furnace

   first. After opening the package, check whether the muffle stove is intact and intact, and whether the fittings are complete. The general muffle stove does not need special installation, only needs to be placed flat on the indoor flat ground or shelf. The controller should avoid vibration, and should not be placed too close to the furnace to prevent internal components from working properly due to overheating.

   Second, there is a thermocouple inserted into the furnace 20-50mm, holes and thermocouples between the gap with asbestos rope stuffing. Connect the thermocouple to the control and use the compensating wire, pay attention to the positive and negative poles, do not answer the reverse.

   Third, in the power cord introduction to the need to install additional power switch, in order to control the total power supply. In order to ensure safe operation, the Muffle furnace and controller must be reliably grounded.

   Four, before use, the temperature meter indicator will be adjusted to 0 points, in the use of compensation wire and cold end compensator, the mechanical 0 points should be adjusted to the cold end compensator reference temperature point, without the use of compensating wire, the mechanical 0 point to 0 scale, but the indicated temperature is the measurement point and thermocouple cold end temperature difference.

   Five, after checking the wiring to confirm the correct, cover the controller shell. Adjust the setting pointer of the temperature indicator to the desired operating temperature, and then turn on the muffle furnace power supply.

   Six, turn on the power switch, at this time the temperature indication meter on the green light is both bright, relay began to work, box type muffle furnace power, ammeter is the current display. With the increase of the internal temperature of the electric furnace, the temperature indication instrument pointer also increases gradually, which indicates that the system is working normally. The heating and temperature of the electric furnace are indicated by the traffic lights of the temperature indicator respectively, the green light indicates the heating, and the red light indicates the fixed temperature.
