PASCO Spectrometry is specifically designed for all levels of students and teachers to integrate spectrometry into the teaching and learning of physics, chemistry and biology. Simply connect a PASCO Wireless Spectrometer (PS-2600) and insert a solution to measure absorbance, transmittance and fluorescence of solutions. The Spectrometry software specifically supports full spectrum analysis along with Beer’s law and kinetics experiments. Use a PASCO Fiber Optics Cable (PS-2601) to easily analyze the spectrum of light emissions.   Key features: • Measure and analyze intensity, absorbance, transmittance and fluorescence. • Auto-set the integration time to determine optimum spectrum • Compare multiple spectra to each other and to a set of reference lines of common elements including Hydrogen, Helium, Mercury and more • Quickly calibrate dark and reference spectra for solution spectrometry • Plot absorbance and transmittance on the same graph • Apply a linear fit to determine relationships • Determine unknown concentration based on standard curves and user feedback • Calculate inverse and natural logarithmic data with built-in calculator functions • Annotate the graph • Take Snapshots of pages for journaling and assessments Common user experience across platforms: Spectrometry provides the same user experience for tablets and computers. No matter the mix of technology in the classroom or the school, teachers and students all share the same user experience--placing the learning experience in the forefront and simplifying classroom management. Awards: • 2015 SIIA CODiE award, Best Education App for a Mobile Device (Finalist) • 2015 BETT award, Digital Devices (Finalist) for the Spectrometer + Spectrometry app Equipment and accessory: The Wireless Spectrometer (PS-2600) and the Fiber Optic Accessory (PS-2601) can be found at pasco.com/spectrometer About PASCO: PASCO Scientific brings a rich history of innovation and support for science education, with 50 years of service to educators around the world. ## Key features - Measure absorbance, transmittance, fluorescence - Full spectrum analysis - Beer's law and kinetics experiments - Compare multiple spectra - Calibrate dark and reference spectra - Plot absorbance and transmittance - Determine unknown concentration ## Recent user reviews (1 of 1) All indexed reviews: https://appshunter.io/ios/app/spectrometry/id893384720/reviews.md ### 5/5 — AP Chem *2023-09-05* It worked 👍 ## Frequently asked questions about Spectrometry ### What can Spectrometry measure? Spectrometry can measure and analyze the intensity, absorbance, transmittance, and fluorescence of solutions. It also supports full spectrum analysis and experiments related to Beer's law and kinetics. ### What equipment is needed for Spectrometry? To use Spectrometry effectively, you will need a PASCO Wireless Spectrometer (PS-2600) and potentially a PASCO Fiber Optics Cable (PS-2601) for analyzing light emissions. These can be purchased from pasco.com/spectrometer. ### Does Spectrometry offer offline functionality? The provided description does not specify whether Spectrometry can be used offline. However, it is designed for classroom integration, suggesting potential reliance on connected hardware. ### How does Spectrometry help with learning? Spectrometry integrates spectrometry into physics, chemistry, and biology education. It allows for hands-on analysis of solutions, comparison of spectra, and determination of unknown concentrations, facilitating deeper understanding. ### What are the key analysis features in Spectrometry? Key analysis features include the ability to compare multiple spectra, calibrate spectra, plot absorbance and transmittance on the same graph, apply linear fits, and determine unknown concentrations based on standard curves. ### Is Spectrometry suitable for all student levels? Yes, Spectrometry is specifically designed for all levels of students and teachers, aiming to simplify its integration into the curriculum. ### What is the update frequency for Spectrometry? The latest version of Spectrometry is 2.5.0, last updated on March 27, 2023. This indicates a relatively recent update, suggesting ongoing development and support. ### Does Spectrometry have ads? No, Spectrometry does not contain advertisements. It is a free application designed for educational use without commercial interruptions. ## Version history (last 5 releases) ### 2.5.0 — 2023-03-27 ====================================================================== Release Notes for Spectrometry v2.5.0 ====================================================================== - Added support for the new PS-2600A BLE capability - Added a Wavelength Calibration Tool ### 2.4.3 — 2022-11-09 This version fixes the issue on 9th and 10th generation iPads where the software would lockup when trying to open a menu or dialog. ### 2.4.0 — 2021-05-19 Improved the smoothing capability ### 2.3.0 — 2021-03-25 - Added support for the UV-Vis Spectrometer - Added Help to the application - Fixed a crash that could occur after calibration. - The unknown values in the table were not being plotted on the graph. This is no longer a problem. - When editing a cell in a table, the entire page (except for that cell) would go black. Squashed that bug. - Fixed an issue where in the Analyze Solution, Absorbance/Transmittance tab, the user was not being prompted to calibrate when they clicked record. ### 2.2.1 — 2019-01-21 Quality Improvements ## Apps similar to Spectrometry | App | Rating | Price | Category | | --- | --- | --- | --- | | [阅燃](https://appshunter.io/ios/app/id1186238420) | — | Free | Education | | [抖英-短视频学英语听力口语](https://appshunter.io/ios/app/id1469348440) | — | Free | Education | | [Asram Education Centre](https://appshunter.io/ios/app/asram-education-centre/id1471096400) | — | Free | Education | | [ABC Agendinha](https://appshunter.io/ios/app/abc-agendinha/id1477111120) | — | Free | Education | | [Teaching724](https://appshunter.io/ios/app/teaching724/id1475513500) | 5.0 (2) | Free | Education | | [试题库](https://appshunter.io/ios/app/id1478850740) | — | Free | Education | ## More apps by PASCO scientific - [SPARKvue](https://appshunter.io/ios/app/sparkvue/id361907181) - [MatchGraph!](https://appshunter.io/ios/app/matchgraph/id884297779) - [PASCO Chemvue](https://appshunter.io/ios/app/pasco-chemvue/id6478240171) All apps by PASCO scientific: https://appshunter.io/developer/361907184 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
