激光测距仪对比超声波线缆测高仪的优点
和超声波线缆测高仪比起来激光测距测高仪是专门为电力，通讯，航空航天等领域的线缆高度及水平物体距离的测量而设计的。针对线缆测量时的瞄准困难，测量距离短，环境影响大，地形条件限制等等问题，激光测高仪都给出了自己的解决方法。
1、在瞄准方式上，仪器采用激光瞄准的方式，光点细小，非常容易瞄准细细的电缆；
2、由于线缆反射面积小，造成超声波测高仪或其他类型的激光测距仪无法测量较高的线缆。而激光测高仪采用线形激光，使测量时的反射面增大到80%以上，测量较高线缆变得简单容易，最大测量高度超过100米；
3、激光测量一般不受环境影响，雨天照样可以进行测量工作；
4、对于地形复杂的环境，激光测高仪可以从远处直接测量出线缆的高度，解决了其它测高仪必须线下方进行测量的问题。

We have a examine at what S . Fransisco-structured skate and streetwear tag HUF has in store for that the summer months 2011 year or so, and already this is far more Cali-cultivated shoes or boots. We begin together with the hightops where the HUF Hupper is back in all of the-black after you have driven lots of attention rolling around in its 4And20 color ways, as the HUF1 swallows a somewhat fewer careful strategy with white and red decorations with a gray suede vamp. All of those other series is trim under the foot, together with the Legitimate chukka to arrive in 2 color ways together with a person all of the Preference, Southerly and Hufnagel Pro. Just click right through to see em all then take hold of one or two from HUF on-line or maybe in-shop.
