A lux meter is a device that measures light and has numerous industrial applications. It's critical to understand what they are, how to calibrate them, and why Testo's lux meters are on the cutting edge of this technology. In any scenario, lighting is an essential aspect that must be considered, not just in industrial settings, but also at home.
What is a Lux Meter?
A lux meter measures brightness in lux, which is equivalent to one lumen per square meter. The device captures the light intensity in its sensor and relays the result through an internal memory system or data logger. Not only is light intensity measurement becoming increasingly significant for safety reasons, but it can also help improve workplace productivity under specific conditions. Furthermore, by selecting the proper lighting levels for your budget, you may save money on your electricity bill. The same light bulb might last longer and be more cost-effective.
Visible light is a critical aspect of workplace safety and employee productivity. Lux meters aid in ensuring that visible light conditions are within acceptable parameters, such as the office or an industrial greenhouse.
How to Use a Lux Meter
Testo offers a range of lux meters to meet your various needs, each with its own set of features. The Testo 540 - Miniature Lux Meter, for example, may provide fast readings while being small and having the perfect measurement range. The majority of the home lighting meters have similar fundamental features, such as brightness and light measurement, but some of them also offer additional functions for various applications.
Lux meters from Testo are highly precise, with three different components that guarantee the process is done correctly. Here are a few examples:
- Light sensor type: This is how the tools view ambient light, similar to how a person's eye does.
- V-Lambda curve: All standard light sources, such as incandescent and halogen bulbs, are assessed with lux meters that use the V-Lambda curve.
- Operation: Testo's light meter may be activated from the operation menu in an easy and intuitive manner. Automatic data loggers increase measurement efficiency and accuracy, as well as reduce the risk of potential human error.
- Display size: The large display aids in the reading of the lux measurements quickly and accurately. This also helps to prevent mistakes when recording measuring values, such as when readings must be recorded immediately.
Extended use features
As mentioned earlier, the lux meters you can purchase from Testo have many extended use features to boost efficiency. Here are some examples:
- WiFi data loggers: The data loggers can store the information they collect and identify when particular limit values are breached once connected to the internet.
- External probes: Small lux probes, for example, are utilized in display cabinets and on exhibition pieces to check light-sensitive items without drawing attention to themselves.
When utilising a lux metre, keep in mind that the amount of light decreases as the tool moves away from the light source, despite the fact that the amount of illumination being produced doesn't change. The light disperses as you get further away, resulting in a smaller reading on the lux meter.
Choosing the Right Lux Meter
Testo offers a wide selection of different measurement tools and related products, each suited for a specific purpose. Here are some of our top recommendations to choose from, depending on your situation and demands:
- Lux meter integrated into the WiFi data logger: This is a great measuring tool for long-term data recording. Combine an air velocity and IAQ logger with an integrated light sensor, temperature, humidity, and UV sensors to ensure that museum lighting conditions and illumination are comprehensively tracked.
- Multifunction measuring instruments with connectable probes: Similar to the above, lux meters often come with many other options and sensors for a multifunctional tool that measures several different parameters. The Testo 400 – Universal IAQ instrument is a great example of this.
- Luxmeter with the built-in probe: The Testo 540 pocket-sized lux meter is an example of a product with built-in measuring probes for fixed items.
Lux meters have a lot of applications, but we know that you want your light levels to be precise and accurate in order to protect worker safety and preserve display items. There can be no doubt that Testo offers a measurement tool to ensure that you receive the most up-to-date information as well as tracked data with precisely designed and wired equipment that can be further calibrated by a specialist to fulfil each requirement.
