What if the high temperature oven is broken? A few tips for troubleshooting

In the process of using the high temperature oven, some faults may occur. What happens when the hot oven breaks down? Don't hurry to send back the oven express, you can directly troubleshoot the trouble!





Kenton high temperature air blast drying oven

1. Plug in and turn on the power switch.



* please ask electrician to help solve the power supply problem.

* if the electric heat pipe is burnt out, the resistance value at both ends of the electric heat pipe can be measured by the multimeter "ohm" file. If the resistance value is several hundred thousand ohms or infinite, it indicates that the wire is blown open.

* the power switch insert is off.

* power switch on, can check the control circuit board and the corresponding connection line.



The temperature cannot rise



* check whether the timing time has run to the timing set value; ★ most users do not understand this function, timing time to the timing value of the heating tube does not work, the fan does not turn, resulting in no heating, the temperature is not up.

.

* check the circuit control board, use the multimeter to check whether there is output, and check according to the drawing;



The motor doesn't work



* result: there is heating, but the inner tank cannot circulate, which causes the temperature to rise slowly. Check whether the fan is in operation. If the fan is broken (use a multimeter to measure whether there is 220V voltage at the two ends of the fan pin), inform the company to mail the accessories to solve the problem.



4. The temperature displayed on the control board is different from the mercury thermometer in the cabinet



Judgment premise:



The thermometer should be measured after passing the inspection of the inspection department.



Measurement and installation position of mercury thermometer: please suspend the thermometer in the center position of the inner cavity, not directly placed on the shelf for measurement.



* refer to the attached parameter adjustment table.



5. The temperature display shows random jump or stationary, or abnormal such as "□□□"



* the problem of temperature sensor can be judged and replaced.



Note: the sensor adopts Pt100 platinum resistance, and the wire ends are two blue and one red.



Above is the high temperature oven broken how to do the detailed solution? Here are a few tips to help you troubleshoot.



Kenton instrument welcome to exchange!

What incubator should I use for fungi?

图片
There are many different types of incubators and the choice of the incubator should depend on what is being cultured. If the microorganism to be cultured is aerobic, then a normal incubator is sufficient; if it is anaerobic, then you need to buy an anaerobic incubator; if it is algae or fungi, it is better to have a light incubator. A light incubator is a piece of high-precision constant temperature equipment with light function; a light incubator is a special constant temperature incubation device for the cultivation of bacteria, molds, microorganisms, and breeding tests, especially practical for biological engineering, medical research, agriculture, and forestry science, aquaculture, animal husbandry and other fields engaged in scientific research and production use of the ideal equipment.　 The main technical parameters of the fungal incubator in the microbiology room of the laboratory require 1: Temperature requirements: 2 ~ 48 c, the temperature inside the incubator temperature u

Laminar flow Cabinet architecture introduction

图片
Laminar Flow Cabinet Clean Bench, also known as laminar flow Cabinet, can be mainly divided into two- person single, single side double side, horizontal vertical, etc. The structure is divided into the box, table, bracket, support foot, exhaust pipe, HEPA filter, pre-filter, etc.   Laminar flow cabinet design should have sufficient strength and stiffness, the weight should be light under the premise of good stability, the joints should be tight, according to the needs of the support foot can be self-locking structure universal wheel, but for the high requirements of seismic workbench without support feet and universal wheel, the operating area of the working surface can be made independent of the box platform. The inner surface of the single table is made of three sides of the wall. The wall surface is smooth and the joint is sealed. The glass and metal connection parts should also be sealed. The negative pressure air duct should be designed so that the air duct, plenum, filter, and su

The Control system is the core of the constant temperature and humidity chamber

图片
The Control system is the core of the constant temperature and humidity chamber , it determines the temperature rise rate of the text chamber, precision, and other important indicators. Now the controller of the test chamber mostly adopts PID control, but also a few adopts PID and fuzzy control phase combination control mode. Because the control system of the thermostatic oscillator basically belongs to the category of software, and this part in the use of the process, generally there will be no problems. In the constant temperature and humidity chamber refrigeration principle diagram, we introduced the temperature and humidity chamber refrigeration system several important components of the working path. So how do these components work? The refrigerant is adiabatically compressed to a higher pressure by the compressor, and the work is consumed to raise the exhaust temperature. After that, the refrigerant isothermally exchanges heat with the surrounding medium through the refrigerant c
