Whether you are monitoring lamp output over time, checking UVB levels at basking positions, or assessing acrylic shield transmission, this meter gives you the data to make informed decisions about your animals' UV exposure.\u003c\/p\u003e\u003ch3\u003eWhat It Measures\u003c\/h3\u003e\u003cp\u003eThe 6.2R reads UVB irradiance across the 280–320 nm waveband — the range most relevant to reptile UVB provision and vitamin D3 synthesis. Its measurement range runs from 0 to 1999 µW\/cm², with a resolution of 1 µW\/cm² and an accuracy of ±10% referenced to NIST standards. Readings update at 3.0 per second, giving a responsive, real-time display on a 3.5-digit LCD with 0.4-inch digits.\u003c\/p\u003e\u003ch3\u003eSensor Technology\u003c\/h3\u003e\u003cp\u003eAt the core of the meter is a Silicon Carbide (SiC) photodiode housed in a hermetically sealed UV glass window cap. A metal oxide interference filter coating blocks the majority of UVA from the response, ensuring the meter reads UVB selectively rather than total UV. The diffuser is constructed from virgin Teflon (.003), and the lens is UV glass — both chosen to preserve measurement integrity across the sensor's working life.\u003c\/p\u003e\u003ch3\u003eBuild and Handling\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eCompact dimensions: 4.2in L × 2.4in W × 0.9in D\u003c\/li\u003e\n\u003cli\u003eLightweight at 4.5 oz including battery\u003c\/li\u003e\n\u003cli\u003ePowered by a single 9V DC battery, functional down to 6.5V — LCD dimming indicates when replacement is needed\u003c\/li\u003e\n\u003cli\u003eBattery life approximately 2 years under typical use\u003c\/li\u003e\n\u003cli\u003eOperating temperature range: 32°F to 90°F; humidity range: 5% to 80% RH\u003c\/li\u003e\n\u003cli\u003eSimple one-button operation — press, hold, and aim the sensor window at the UV source\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003ePractical Applications for Reptile Keepers\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eMonitor UVB output of reptile lamps and track lamp ageing over time\u003c\/li\u003e\n\u003cli\u003eCheck output at basking position to verify animals are receiving adequate UVB\u003c\/li\u003e\n\u003cli\u003eTest UVB transmission through acrylic vivarium shields or covers\u003c\/li\u003e\n\u003cli\u003eCalculate percentage UVB when used alongside a Model 5.7 total UV reading (UVA + UVB)\u003c\/li\u003e\n\u003cli\u003eCompare output between old and new lamps of the same type to determine replacement timing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eCorrect Use and Lamp Ageing Guidance\u003c\/h3\u003e\u003cp\u003eAllow lamps to warm up for at least 5 minutes before taking readings, and always measure from a consistent distance and position when tracking ageing. As a general guide, lamps producing 30% less output than their original new reading — dropping to around 70% of that initial value — should be considered for replacement. Always wear UV-blocking eyewear when working with UV lamps directly, and keep the sensor free of oil and dust, cleaning only with a dry, soft cloth.\u003c\/p\u003e\u003cp\u003eThe Solarmeter 6.2R puts objective, reproducible UVB data in your hands — removing the guesswork from lamp management and giving you confidence that your vivarium lighting is genuinely delivering what your reptiles require.\u003c\/p\u003e","brand":"Peregrine","offers":[{"title":"Default Title","offer_id":54147190128977,"sku":"CSR062","price":291.41,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0963\/0403\/8225\/files\/CSR062_1.jpg?v=1783132557"},{"product_id":"solarmeter-6-5r-uvi-radiometer","title":"Solarmeter 6.5R UVI Radiometer","description":"\u003cp\u003eThe Solarmeter 6.5R UVI Radiometer is a precision UV index meter designed for reptile keepers who need accurate, reliable UVI readings from vivarium lamps and outdoor sunlight.
