The Extech SDL470 measures both 365 nm UVA and 254 nm UVC energy with a single handheld body, and it does so with ±4 % full-scale accuracy. Thanks to its cosine-corrected sensors the readings stay trustworthy regardless of lamp angle, and therefore routine compliance checks remain swift.
Instant Data Capture
Operators tap one key and the Extech SDL470 stores every result to an SD card, and the files open directly in Excel so reporting time plummets. Manual recall holds ninety-nine readings for quick checks on site, while automatic logging scales effortlessly to long validation runs.
Built-In Thermal Insight
A Type K or Type J thermocouple input extends the Extech SDL470 into temperature surveys as well, and that means lamp ageing effects can be tracked in real time. The wide –100 to 1300 °C span lets technicians verify both cryo storage and furnace chambers without swapping instruments.
For field service the Extech SDL470 ships with a rigid case, a universal AC adaptor and six AA batteries, so work can start on arrival. Its tilt stand keeps the screen within easy sight, and auto power-off preserves battery life during lengthy audits.
