Import Black Light Irradiation Meter Uvv420 — Buy in wholesale FOB from Supplier in China

The UVV420 is a handheld black light irradiation meter engineered for quantitative measurement of ultraviolet radiation in the near-UV to visible violet band. It operates across a spectral range of 375nm to 475nm with peak transmittance centred at 420nm, making it suitable for monitoring UVA and long-wave UVV output from black light sources used in fluorescent penetrant inspection, leak detection, and UV curing verification. The instrument provides direct irradiance readings in standard radiometric units rather than relative indices, which supports traceable calibration protocols in industrial quality systems.

The detector head typically incorporates a silicon photodiode with a narrow-band interference filter calibrated to the 420nm peak, with cosine-corrected geometry to accommodate off-axis radiation. Standard construction uses an aluminium or ABS housing with a digital LCD display, internal memory for logged measurements, and battery power for field portability. Response linearity across the stated bandwidth is a standard performance parameter for this instrument class, though the specific tolerance and calibration certificate details for this unit are not stated in the listing and should be confirmed with the supplier.

Buyers are typically quality control engineers, non-destructive testing (NDT) technicians, and facilities managers in manufacturing, healthcare sterilisation monitoring, and environmental compliance roles. The instrument is used to verify that UV lamp output remains within process specification limits, preventing under-cure in adhesive or coating applications and ensuring operator safety in exposure-critical environments. Packaging, MOQ, and lead time are not specified in the source data and must be discussed directly with Shenzhen Sanpo Instrument Co., Ltd.

Shenzhen Sanpo Instrument Co., Ltd. is based in Shenzhen, China, with a registered address at Room 905, 908 and 910, 8th Building in the Futian district area (postal code 518000). The supplier holds a 'harbor' trust tier classification, which represents a baseline verification level on the platform. The response rate is recorded at 0.00% with an average response time of zero hours, indicating that no response data is currently available for this supplier. Buyers should note that the profile does not disclose years in operation, factory size, or internal quality management certifications.

The listing presents the UVV420 black light irradiation meter as the supplier's offering, with emphasis on portable design and industrial durability. No additional product range, OEM capability, or export experience is mentioned in the source material. The supplier's specialisation appears to be in measurement instrumentation, though the breadth of their catalogue and their technical support capability for calibration or after-sales service are not specified. Any claim regarding manufacturing versus trading status, ISO certification, or client references would need to be verified directly with Shenzhen Sanpo Instrument Co., Ltd.
