UVC254 : เครื่องวัดแสง UVC Light Meters, ยี่ห้อ Nicety
Accurately measure UVC
UVC light meter is a precision instrument and is operated correctly. The measured value will be slightly low with narrowed measuring range if it is operated improperly. It is suggested to seal the instrument and drying agent with tape when it is standby and replace the drying agent regularly. Therefore UV sensor will be used for a long time.
The instrument is applicable to the measurement of UV radiation intensity in fields of sterilization, photoetching, water treatment, health care and breeding.
