It can sample and measure light source parameters anytime and anywhere, and can also be connected to PC software test in the laboratory to efficiently analyze and process the test data saved by on-site test, with extremely high measurement linearity and accuracy.\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan class=\"a-text-bold\"\u003eApplication standards:\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul class=\"a-unordered-list a-vertical\"\u003e\n\u003cli\u003e\u003cspan class=\"a-list-item\"\u003eGB 40070-2021, JJG_245-2018, GB55016-2021, GB∕T 5702-2019, GB∕T 5702-2019, GB∕T 5699 -2017, GBT 5700-2008, GBT 24824-2009, GB30734-2014, GBT 9473-2017 and other lighting standards.\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan class=\"a-text-bold\"\u003eMain test functions:\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul class=\"a-unordered-list a-vertical\"\u003e\n\u003cli\u003e\u003cspan class=\"a-list-item\"\u003eSingle test, continuous test, timed test, multi-point test, timed save.\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan class=\"a-text-bold\"\u003eGraphical interface:\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul class=\"a-unordered-list a-vertical\"\u003e\n\u003cli\u003e\u003cspan class=\"a-list-item\"\u003eCIE1931, CIE1960, CIE1976, color rendering index, spectral similarity index, spectral fit\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan class=\"a-text-bold\"\u003eDisplay interface:\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul class=\"a-unordered-list a-vertical\"\u003e\n\u003cli\u003e\u003cspan class=\"a-list-item\"\u003e3.5-inch touch screen, mobile phone APP, WeChat applet, PC software\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan class=\"a-text-bold\"\u003eSave and share format:\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul class=\"a-unordered-list a-vertical\"\u003e\n\u003cli\u003e\u003cspan class=\"a-list-item\"\u003ePicture format, PDF file, EXCLE original data\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan class=\"a-text-bold\"\u003eData storage:\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul class=\"a-unordered-list a-vertical\"\u003e\n\u003cli\u003e\u003cspan class=\"a-list-item\"\u003eData saved by mobile phone APP, applet, PC software, touch screen are interconnected\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan class=\"a-text-bold\"\u003eMeasurable items:\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul class=\"a-unordered-list a-vertical\"\u003e\n\u003cli\u003e\u003cspan class=\"a-list-item\"\u003e1) Correlated color temperature Tc\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan class=\"a-list-item\"\u003e2) Illuminance lx\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan class=\"a-list-item\"\u003e3) Irradiance Ee(W\/m²)\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan class=\"a-list-item\"\u003e4) Color coordinates (x,y), (u,v), (u ′,v ′)\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan class=\"a-list-item\"\u003e5) Relative spectral power distribution P(λ)\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan class=\"a-list-item\"\u003e6) Color rendering index Ri(i=1~15)\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan class=\"a-list-item\"\u003e7) Color rendering index CRI (Ra);
