Light Meter LM vs HPLC Advisor

Turn your smartphone into a professional-grade light meter. Measure illuminance (lux/foot-candle) and color temperature (CCT in Kelvin) with unmatched accuracy — trusted by photographers, engineers, and lighting professionals worldwide. Why waste money on a hardware meter when you’re already carrying one in your pocket? The LM-3000 offers the same quality and usability as a traditional hardware light meter. Developed by optics scientists at the Zurich University of Applied Sciences, LM-3000 is the only light meter app scientifically validated for accuracy. It achieves professional-grade precision by leveraging your iPhone's front-facing camera sensor with advanced RAW image processing. Unlike relying on estimates like other apps, it adheres to the ISO/CIE 19476 standard, ensuring measurements you can trust for critical applications. MEASUREMENTS ⎷ Illuminance in lux or foot-candles ⎷ Correlated color temperature in kelvin FEATURES ⎷ Industry-leading accuracy, matching professional high-end lux meters ⎷ Pre-calibrated for your specific device ⎷ Excellent low light sensitivity to detect light pollution ⎷ No ads ⎷ No Bluetooth and location permission required ⎷ In-app manual ⎷ Save peak reading ⎷ HOLD function with acoustic signal ⎷ Custom calibration option to align readings to another meter DIFFUSER REQUIRED Like every real light meter, the LM-3000 requires a diffuser to measure accurately. A diffuser scatters incoming light evenly on the sensor and prevents hotspots. While it may sound complex, the solution is surprisingly easy. You have two options: 1) Easily build a diffuser yourself in less than a minute using standard printer paper. This is accurate enough for most use cases. 2) Get the dedicated Diffuser Accessory (free worldwide shipping) for best accuracy and convenience. More details on https://lightray.io/diffuser/ (!) Avoid apps that don’t require a diffuser! They are inaccurate because they ignore the basic physics of light measurement. TRY BEFORE YOU BUY The LM-3000 is free to download and comes with a free trial period. The trial period lasts for two non-consecutive days, giving you enough time to see if the app fits your needs. The status of your free trial will be shown as the "battery level" on the top right of the LM-3000's display and on the "Battery Status" screen. Once your light meter's "battery" is depleted, you may choose a Charging Option to keep using the app. You can pick what works best for you: → Single Charge — top-up for another 48 hours (perfect for occasional use), → Continuous Charging — a monthly subscription (great if you use it regularly), → Unlimited Battery — a one-time purchase for unlimited lifetime access LM-3000 is the result of over five years of dedicated research and development, ensuring you get a tool that is precise and reliable. Every in-app purchase supports future development and helps keep the app ad-free for everyone. As a member of 1% for the Planet, we donate at least one percent of all revenue to environmental non-profits — this is our way of giving back. ACCURACY Accuracy is not an afterthought — Apps developed by Lightray Innovation are developed according to the ISO/CIE 19476 standard. Thanks to RAW image processing and a default calibration per device model they’re able to match the performance of high quality traditional hardware light meters. To ensure quality we rigorously test our apps regularly on upcoming devices. DOWNLOAD FOR FREE. TRUSTED BY MILLIONS. LM-3000 is the go-to light meter for photographers, professionals, engineers, and lighting enthusiasts who rely on accurate measurements — not estimates or guesswork.

The Agilent InfinityLab HPLC Advisor app offers tools to save you time with HPLC troubleshooting, method development, and more. Once installed, it works also offline—no matter if you are next to or away from the instrument. Moreover, these tools work for all HPLC instruments, regardless of brand and model. Troubleshooting Typical HPLC problems are summarized and organized in groups—so you can quickly define the issue in a couple clicks. For each problem, you can choose to view all potential issues for tips or get guided step-by-step help to troubleshoot your issue. This flexible app offers two ways to help users solve their HPLC problems. Calculators Method translation This calculator helps you translate your legacy methods to new columns and systems. Simply enter the information from your legacy method (column, system, experimental conditions, and gradient) along with the new column and system that you are going to use. Then, the calculator determines the experimental conditions and the gradient of your new translated method. For all fields in these calculators, you can either use default values or values that are specific to your method, column, and system. All results can be saved as a PDF. Chromatographic performance This calculator helps you predict how a chromatographic method will perform. Fill in parameters such as column geometry, system dwell volume, mobile phase, experimental conditions, etc. Then, this app will calculate the expected chromatographic performance (e.g., gradient slope, number of plates, peak capacity, backpressure, optimal flow rate). For all fields in these calculators, you can either use default values or values that are specific to your method, column, and system. All results can be saved as a PDF. Data Library Conversions This section shows you LC-related information, such as the conversion factors between different units, details of selected physical constants, powers of ten, and concentration values. Formulas This section lists LC-related formulas. The search function helps you find formulas easily and quickly. All formulas, as well as all related parameters, are listed and linked to other related formulas if applicable.
