  At the end of the day, I’m a staunch advocate of working very hard and making financial sacrifices in order to bring your business to life without going into debt or sacrificing partial ownership of your idea. If that means growing your business a little slower than you otherwise would, then in most cases I’d argue that’s a worthy cause—in order to retain ownership and not expose yourself to as much financial risk.Z E I g ey

  T PIWhen I first launched this blog, I knew that traffic building was going to be my biggest challenge. All of my plans hinged on my ability to build traffic. If I couldn’t build traffic, it was going to be very difficult to succeed. So I didn’t even try to monetize my site for the first several months. I just focused on traffic building. Even after 19 months, traffic building is still the most important part of my monetization plan. For my current traffic levels, I know I’m under-monetizing my site, but that’s OK. Right now it’s more important to me to keep growing the site, and I’m optimizing the income generation as I go along.K T F

      扬尘检测仪现在好多地方都要用到了,一般传统的扬尘检测仪利用光散射法原理,容易受到湿度的干扰,而湿度大了会显得数值偏高,而且光散射法误差大,数据并不十分精准。贝塔射线扬尘在线监测仪具有自动除湿、自动校准和报警功能,以及数据采集、传输、存储、分析和处理功能,从而更准确地监测各种粉尘污染数据,促进城市空气质量的改善。
      贝塔射线扬尘监测仪就是基于β射线法研究的监测仪器,其实原理并不是很复杂。通过利用β射线衰减测量技术,再结合其他设备,24h自动监测PM2.5、PM10颗粒物浓度。β射线扬尘监测仪主要由4个部分组成——采样、测量、传动及数据处理,实现建筑工地扬尘污染在线监测、管理一体化,提高科学管理的效率和能力,掌握施工现场粉尘污染的真实情况。
      贝塔射线扬尘在线监测仪由监测子站与数据平台构成。监测子站集成了噪声监测、大气颗粒物浓度监测、气象五参数、七参数视频监控及污染物超标视频抓拍、有毒有害气体监测等多种功能;数据平台是一个互联网架构的网络化平台,具有对各子站的监控功能以及对数据的报警处理、实时查询、记录、统计、趋势图显示、报表输出等多种功能,并能及时、准确地通过网络传给各个管理部门,简单易用。
     

     

      贝塔射线扬尘在线监测仪作用与优势:
      1、使用智能加热技术对采样空气动态加热除湿,提高测量精度。
      2、使用PID恒流算法,泵转速调控自适应,保证采样空气流量稳定精准。
      3、使用五级校准法,确保PM10浓度无论高低皆能准确测量。
      4、使用全程零点校准,保证每一次测量都不受滤纸均匀度的影响。
      5、采样周期连续可调,最小周期3分钟,最大周期60分钟
      6、支持省纸模式,滤纸可根据使用情况循环利用,能有效延长滤纸使用时间。
      7、贝塔射线扬尘在线监测仪支持本地数据查询展示,可查询任意时间段数据。
