Testo 545 Digital Lux Meter with App Connection

The Testo 545 Digital Lux Meter (0563 1545) helps Aussie tradies and WHS pros quickly and accurately measure illuminance from nearly all common light sources. This compact unit is essential for anyone needing to verify lighting levels in commercial, industrial, or office environments to meet safety and productivity standards.

Anyone who's done a site audit knows how quickly poor lighting can chew into productivity or cause eye strain. This meter is designed to give you reliable data without fuss, directly on the job.

Best For

• Electricians and HVAC technicians
• Workplace Health and Safety (WHS) officers
• Property managers and facility maintenance teams
• Building commissioning and energy auditors

Compatibility

The Testo 545 is designed for use with almost all common light sources, including most commercially available LEDs. It accurately measures illuminance according to the V-lambda curve, ensuring reliable readings across diverse lighting setups.

If you're running a different model or working with highly specialised lighting, check fittings and specs before ordering.

Features

• Precise Illuminance Measurement: Get simple, fast, and accurate lux readings for all standard light sources, following the V-lambda curve.
• Broad LED Compatibility: Works with most common LEDs, expanding its application range across modern lighting installations (Note: not compatible with single-colour blue LEDs).
• Testo Smart App Integration: Configure the meter, view graph history, use your smartphone as a second screen, and store or document measurement data directly in the app.
• Audible Alarm: A built-in alarm sounds if user-defined limit values are exceeded, providing immediate notification for out-of-spec conditions.
• Automatic Averaging: Automatically calculates time and point average values, simplifying complex lighting assessments.

What's in the Box

Using It on the Job

1. Power Up & Connect: Insert the included AA batteries, power on the meter, and optionally connect it to the Testo Smart App on your smartphone for enhanced functionality.
2. Position Sensor: Place the meter's sensor at the point of measurement, ensuring it's not shadowed by your body or other objects to get accurate readings.
3. Take Measurements: Activate the measurement function. The meter will display illuminance in lux. Use the app for real-time monitoring and to set up averaging functions.
4. Monitor Limits & Document: Keep an eye on the readings or set audible alarms in the app for limit breaches. Save data and generate reports directly from the Testo Smart App for compliance or client records.
5. Post-Job Care: Wipe the sensor clean with a soft cloth after use and store the meter in its transport bag to protect it from dust and impacts.

Limitations & Safety Notes

• Not compatible with single-colour blue LEDs; accuracy may be affected.
• Always follow local Australian Workplace Health and Safety (WHS) guidelines for lighting assessments.
• Keep the light sensor clean and free of obstructions for accurate readings.
• Ensure batteries are charged before critical measurements to avoid interruptions.

Tradie Pro Tip: When you're assessing large areas, use the Testo Smart App's averaging function. It saves you from manually noting multiple points and helps you get a reliable overall picture quickly. Makes reporting much easier.
