Description
Testo 545 Digital Lux Meter (0563 1545) — a compact, Class C illuminance meter that lets technicians quickly verify workplace lighting, tune LED installs and document results with the Testo Smart App. It measures 0–100,000 lux to the V-lambda curve and sounds an audible alarm on threshold breaches. No dramas—fast, accurate, and built for Australian job sites.
Key Features & Trade Benefits
- 0–100,000 lux range, V-lambda compliant — capture office, warehouse and task lighting accurately, so your AS/NZS lighting checks hold up.
- Class C per DIN 5032-7 / EN 13032-1 — the right accuracy class for reliable workplace assessments and fewer call-backs.
- LED-ready (excl. single-colour blue LEDs) — one meter for today’s LED installs and retrofits.
- Smart App workflow — configure thresholds, view trends, store readings and export PDF/CSV reports straight from site—too easy.
- Timed & point averaging — document realistic lighting performance over time, not just snapshots.
- Audible limit alarm — set min/max lux targets and get a beep when levels drift—saves time during audits.
- Rugged, lightweight build (IP40 instrument) — easy to carry and tough enough for daily site work.
Why This Product Matters
On a Sydney office fit-out, you’re checking task areas after an LED swap. With the 545, you’ll nail the 300–500 lx brief in minutes, log averages, and export a clean report before the lift hits ground. Fair dinkum time-saver. If you’re comparing options, see our Environmental Testers to build out your test kit.
Tip: Many AU regulators reference the AS/NZS 1680 series for interior/workplace lighting—use a compliant meter and document it properly.
Pro Tip
Hold the remote sensor flat at the work plane (e.g., desk height), avoid shading with your body, then log multi-point and timed averages for each zone. Name locations in the Smart App as you go—she’ll be right when the report lands.
Compatibility & System Info
- Light sources: All common lamps incl. LEDs (excl. single-colour blue LEDs).
- Smart App: iOS 13+ / Android 8.0+ via Bluetooth (BLE 4.2 or higher).

Local Jobsite Note (AU)
From bright retail fit-outs in Melbourne to big shed aisles in Brisbane, ambient glare and skylight spill can throw readings. Use timed averaging and the alarm to keep it tidy—no worries.
