Improve results when doing surface coating and concrete pouring. Ensure worker and equipment safety by knowing accurate local weather conditions.For years construction professionals have been using Kestrel Meters to monitor the weather on the job site. Now NK has partnered with industry experts to develop a customized Kestrel instrument for construction professionals who place concrete.Features","Calculates Evaporation Rate","The new Kestrel 4300 Construction Weather Tracker measures and displays evaporationrate — a function of relative humidity, temperatureand wind speed. Evaporation rate is a critical environmental indicator that concrete contractors use to ensure they avoid plastic shrinkage cracks in concrete installations especially concrete flatwork. Plastic shrinkage cracks occur when the surface of the concrete dries too quickly and shrinks before the bed has cured enough to resist cracking. This is especially relevant in specialty applications like decorative concrete, Ready Mix Concrete (RCM) and Tilt-up concrete.","Helps Prevent Plastic Shrinkage Cracks","Plastic shrinkage cracks can be prevented by properly assessing the weather and the fresh concrete conditions. Previously, construction contractors used a Kestrel Meter to measure the relevant conditions, then referenced an American Concrete Institute chart to calculate the evaporation rate. The new Kestrel 4300 Construction Weather Tracker does the work for them! The user simply enters the concrete temperature (obtained via an infrared thermometer or probe thermometer*) and the 4300 calculates the evaporation rate instantly. In addition to evaporation rate, the Kestrel 4300 remains the perfect rugged all-purpose construction weather tool, measuring and logging the following relevant weather conditions right where the workers and equipment are operating.","For maximum accuracy when measuring the evaporation rate:","For the best accuracy, use the Kestrel's convenient averaging mode to average the evaporation rate over the recommended 6-10 seconds.","Documents Work Conditions
多年来,我们的客户一直要求风向与风速一致。新的2007年,红隼4500做的只是它的内置数字指南针。但它不会就此停止。它还参照用户设置的目标航向计算侧风和逆风/顺风,并将信息和所有其他环境读数存储在其1400数据点存储器中。,把4500测风仪和红隼叶片安装在一起,你就有了一个数据记录气象站,它在几秒钟内建立起来,在微风中旋转。我们有没有提到整个套件在便携性上是最棒的?它可以装进一个2 x 6英寸的袋子里,重量不到8盎司。,在NV配置中可用,在黑暗中飞行的军事人员和飞行员经常关心保持他们的夜视。由于来自我军客户的巨大需求,红隼NV系列于2005年增加。红隼4500NV具有夜视保护背光,帮助用户维持自然夜视。NV的背光包含一个光学滤光片,以降低整体亮度,并尽量减少蓝色和绿色光谱光,以保持夜视。此外,NV背光也比标准背光暗得多,使得在夜间操作中更难用肉眼检测。这种背光灯呈现柔和的灰粉色,而不是红色,而且仍在可见光谱范围内,因此与夜视设备不兼容。,一般眼睛需要30到45分钟才能适应黑暗并最大限度地提高夜视能力。即使是短暂的白光、黄光、绿光或蓝光也会滤过眼睛中的视杆细胞感光细胞,导致夜盲症,直到整个适应过程再次发生。红色光谱中的光不会导致这种情况,防止夜盲和夜视疲劳。特征,红隼4500措施,红隼4500附加特征
