The Luo Wei Peng colorimeter is an instrument for measuring the color of an object. In the grain and oil detection, the Luo Wei Peng colorimeter is also widely used. However, as a professional detector instrument, it is necessary to extend the service life of the instrument. To play the instrument's efficient and accurate measurement performance, then we must pay attention to the maintenance and maintenance of the instrument. Here is a brief introduction to the daily maintenance of the Lovibond colorimeter .
The structure of the Luo Wei Peng colorimeter is simple, mainly composed of observing system (including eyepiece tube, white background observation room), sample chamber, color filter combination filter holder, light source and sample cell. The daily maintenance should be carried out around each part. The main maintenance contents are as follows:
1, light source bulb
During the operation of the Lovibond colorimeter, since the bulb will be naturally damaged, the lumen of the two light sources will be different from the measurement results of the contrast meter. Therefore, the bulb that has been naturally damaged should be replaced in time, and generally It is to replace both bulbs at the same time. During the replacement of the lamp, pay attention to the operating specifications to avoid some danger. Also avoid direct contact with the bulb to avoid reducing the life of the bulb.
2, sample compartment
When the colorimeter is used, there is a case where the sample overflows. The spilled samples must be cleaned up in time to clean up the emergency in case of spillage, and the sample compartment is designed to facilitate this. When cleaning and replacing the sample compartment, the same as the light source bulb replacement operation, after the sample compartment is replaced and cleaned, it is necessary to check whether the optical path system is normal and whether the sample compartment and the instrument are tightly coupled.
3, sample pool
After the sample is tested using a colorimeter, the sample cell should be cleaned in a timely manner. Because of the different material properties of different sample types, different sample cleaning methods are used. Generally, the sample pool is cleaned without using materials such as cloth, and the sample is cleaned according to different samples using laboratory cleaning agent and corresponding cleaning method, and then washed and dried to achieve the purpose of sample pool cleaning, in the sample pool. When storing, pay attention to the maintenance of its observation window and prolong its service life.
4, observation tube
For contaminated observation cylinders, timely cleaning is required. The general observation cylinder is capable of being removed for cleaning. However, when installing after disassembly and cleaning, pay attention to check whether the optical path is smooth and strengthen the lock.
The above is the introduction of the daily maintenance methods of the Luo Weipeng colorimeter. In the past, the above content can help the correct use of the instrument.
We producesquare steel bar by cold drawing through square mould from hot rolled steel round bar or hot rolled square steel bar. In this way, square steel bar has precision size tolerance, better surface and sharp corner radius. Except cold drawn square steel bar, we can also produce heat treated square steel bar. For example, annealed square steel bar, qhenched and tempered Q&T square steel bar. After heat treatment, you can get the proper square bar hardness according to your end usage. For heat treated square steel bar, straightness is very important. We have fine straightening machine to do straightening to keep good straightness.
