紫外线照度计型号325
照度计特点
- 探头到探头可重复性小于1%。
 - 实时测量。
 - 单通道探头
 - 双通道探头功能
 - 可互换的探头
 - 计算机接口
 - 余弦响应探头
 - 测量mw/cm2,峰值mw/cm2,mj/cm2(SP),累积mj/cm2(总时间-秒)和累积时间(总秒) 计算mw/cm2的平均值,计算mw/cm2的%均匀度和%偏离中心值 X10 范围
 - 电池在充电前大约可持续工作 18 小时
 - 充电器可从 100-240 VAC、50-60 Hz 运行,具有 UL、CE 和 TUV 批准
 
全面的UV光测量
仪器 Model 325 的内置计算机可以存储传感器读数并计算平均值和百分比偏差。两行显示格式允许同时进行多次读数。Model 325 测量 MW/CM2、峰值 mw/cm2、mw/cm2 和时间(单脉冲),并具有平均 mw/cm2 和峰值 mw/cm2。
Model 325 有四种操作模式。5点mw(mw/cm2)和5点mj(mj/cm2)允许以固定模式进行五次读数,然后显示平均值以及+/-%均匀度和+/-%偏离中心值。
可充电电池可持续使用约18小时,充电器工作电压范围为100-240 VAC,50-60 Hz,具有UL、CE 和 TUV 批准。
Model 325 可使用各种传感器包,在220nm至540nm及以上波长范围内工作。与NIST的可追溯性为+/-3.0%,探头匹配精度为+/-1.0%。
