{"product_id":"zoo-med-uvb-meter","title":"Zoo Med UVB Meter","description":"\u003cp\u003eA digital radiometer that reads ultraviolet output in microwatts per square centimetre. Its job is to tell you when a UVB lamp is spent — fluorescent and mercury vapour lamps keep producing visible light long after their UVB has faded, so without a meter the only guide is the calendar, and calendars are conservative by design.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat it does\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\u003cstrong\u003eReads UV output in µW\/cm².\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTracks decay over time\u003c\/strong\u003e — compare today's reading with the one you took when the lamp was new.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e9V battery\u003c\/strong\u003e — included and fitted, with a low-battery indicator.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eAn important limitation\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThese readings are \u003cstrong\u003erelative, not absolute\u003c\/strong\u003e. Different lamp types have different spectral outputs, so a µW\/cm² figure from a T5 tube cannot be compared with one from a mercury vapour lamp. Use it to track a single lamp against itself over time, taking readings from a consistent distance and letting the lamp warm up for five minutes first.
