ST-900B industrial and laboratory weak light illuminance meterIt has a smaller detection range and higher resolution than a low light illuminance meter. Using liquid crystal digital display and silicon photodetector, the spectrum undergoes strict calibration. Can be used for illuminance measurement in industry and agriculture.

In order to provide better convenience for users, our company also provides measurement and inspection services on behalf of customers. We can send certificates of qualified standards issued by third-party national measurement and testing institutions according to user needs. If users need to submit for inspection, they can inform us in advance.

Zhuhai weak light illuminance meter sales, one-year quality warranty, lifetime maintenance, allowing you to use it without any worries. Different from traditional illuminance meters, it can meet the needs that traditional illuminance meters cannot detect. Three different models to meet different testing needs.
