Let’s first talk about the occasions where people will use office chair. Office chairs are mainly used in work places. This is undoubted, because most of your work time is done in the office, and then at home. This is also the topic of this article: do I have to office chairs for back and neck problems at home?

Why buy an ergonomic office computer chair for back and neck problems

With the continuous development of information technology, everyone's work has gradually transformed from manual labor to mental labor. Many people no longer need to work by themselves. They are all using modern machine automation, and there are many design and scheme actions that are even more difficult. It requires manual labor. Most of them work on computer chairs, so computer chairs have become an essential piece of furniture in our lives.

The so-called ergonomic chairs, compared to everyone already know what kind of office computer chair is ergonomic, so is it necessary to buy leather office chair at home? This needs to be decided according to the situation, according to their needs. Here’s the discussion to whether it is suitable to buy ergonomic office computer chair at home according to several kinds of people.

Discuss who needs to buy an ergonomic office computer chair for back and neck problems at home

Some people work most of the time in the office and work at home for a short time. In this case, these people do not necessarily have to buy an ergonomic computer chair, because most of their work is done in the office. After returning home to rest and relax, if they still spend more time using computer chairs, they can choose to buy ergonomic computer chairs according to their economic level and home decoration style. They should consider the computer chair price, style and how much they like certain chair. Buy a suitable office computer chair for their own good at home.

Busy at work, usually with little exercise, some people still need to complete their work at home for a while. For these people, it is recommended to buy ergonomic computer chairs at home, because these people work longer hours and are already exhausted in their own spine. There is still some work to do at home, so at home they should also take good care of their body. The home computer chair must conform to ergonomic principles, which is the first consideration.

As for the elderly and children, because the body of the elderly is not as strong as the young, the bones need more protection. Because children are growing, it is important to maintain the normal curve of the bones. Therefore, people with elderly and children at home must buy computer chairs that conform to ergonomic principles.

In a word, the choice of buying what kind of home computer chair is more flexible. Whether one has to buy an ergonomic office computer chair at home must be decided according to each person's own situation, and according to each person's need. No matter what style of the computer chair is, it must be the most suitable. Want more details of different kinds of computer chairs that victorage can offer?

Overview

WDet-5000UVI is the first full-spectrum (200-800nm) immersion UV water analyzer at home. With features of the delicate and convenient structure, plug and play, auto cleaning function, it can be widely applied to measure indexes including COD, BOD, and turbidity in surface water, underground water, and municipal sewage.

Technical Principle Of WDet-5000UVI Immersion UV Water Analyzer

The portable water quality analyser adopts a pulse xenon lamp as the light source and ultraviolet spectrometer as a detector, which can collect the absorption spectrum of water pollution between 200nm and 800nm in real time. The water pollutant content can be analyzed in real time through the chemometrics algorithm technology. The optical path is shown as the following figure.

The spectral probe can record a complete spectrum between 200nm to 800nm (UV-visible light) and distinguish the spectrum into 256 wavelengths to obtain "Spectral fingerprint". It can monitor multiple parameters simultaneously through the information contained in spectral fingerprint and compensate those parameters aiming at possible cross-sensitivity. The relevance between measuring result and laboratory result achieves high quality that simple optical instrument can never obtain before.

Features Of WDet-5000UVI Immersion UV Water Analyzer

Adopt a full spectrum (200-800nm) (UV-visible light) measurement technology and chemometrics algorithm. Compared with dual wavelength background deduction technology, it can measure more parameters and be less affected by composition change of sewage.

Use high-pressure gas to clean probe automatically, or employ immersion electrical brush to clean.

Not required for reagent preparation; save operating cost and no secondary pollution.

Fast response time(about 2s), applied to occasions with high requirements for real-time.

Without interference by chloride.

Volatile Organic Compounds (VOCS) are carbon based compounds that pose a significant health hazard due to their toxicity. VOCs online monitoring system adopts PIO (photoionization detector ) for gas detection. The target gas is irradiated I bombarded by ultraviolet light produced by the ion lamp, and is ionized after absorbing enough uv energy. The concentration of the target gas can be detected by detecting the tiny current generated after the ionization of the gas.

The system consists of sampling unit, condensing unit, zeroing unit, calibration unit, display unit, pressure alarm unit and analysis instrument. The sample gas enters into the PIO under the action of filtration and condensation of the suction pump. The detector transmits the processed concentration signal to the display unit, the end user, and the EPA platform. The user can set the auto zeroing and calibration period according to the actual situation. While the pressure alarm unit outputs a pressure alarm signal when the injection port of the analysis instrument is blocked, prompting the end user to clean the filter in time.
