Shipping Policy : Battery Not Included During the Shipping Introduction UV power meter can measure the UV energy density, UV irradiance and temperature at the same time. It can be used to: 1. Detect the UV energy density, UV irradiance and temperature of UV curing machine which using UV LED light source. 2. Measure the UV irradiance and temperature of machines which using UV LED light source, such as UV drying machine, exposure machine and printing machine etc. Technical Specifications Spectral range: 340nm --- 420nm Irradiance measuring range: 0 --- 20000mW/cm2 Irradiance resolution: 1 mW/cm2 Energy measuring range: 0 --- 999999mJ/cm2 Energy measuring accuracy: +/-10%, +/-5% (typical) Temperature measuring range: -50°C --- +125°C Sampling speed: 2048 times/second Irradiance data storage interval: 32 times/second Temperature data storage interval: 2 times/second Recording period: 32min Power supply: 2 AAA alkaline dry batteries（Battery Not Included In the Package） Display: 240*160 Dot matrix LCDDimension: Diameter 120mm * thickness 13 mm Weight: 327g Features It is equipped with a USB port, and the computer software can read the record data, drawing curves and print out testing reports. It has a high precision fast response temperature sensor and can measure the real temperature in the curing machine dynamically.It has a built-in heat resisting sheet, can resist high temperature and operate at 100oC for long time.A built-in large memory and can record irradiance data up to 60,000 and temperature data up to 3800.The stored data will not be lost when the the power is off and the last testing data will be displayed automatically when power is on; the test data can only be deleted manually.It is with high accuracy, and has passed many tests of authoritative testing organizations and got certificates.
