Step-By-Step Instructions - At Your Fingertips • Standardize Procedures - Step-by-step illustrated instructions are integrated into the app - this ensures everyone has the same set of procedures and that those important details necessary to achieving excellence in measurement are followed. • Quick and easy access to “pro-tips.” Anywhere in the app that the information graphic appears, be sure to click. These pages contain additional information about the instrument and turbidity measurements. • Fingertip Access - Leave the manual behind! Always have access to the latest features and updated instructions by using the AquaLXP App. Complete Instrument History • Every logged reading, calibration, verification, cleaning or other maintenance performed on a sensor over its lifetime is stored in one place - on the sensor. The AquaLXP™ App allows the user to easily access that information at any time. • By connecting to a PTV Sensor with a smart device, an operator, supervisor or regulator can easily confirm if scheduled verification/calibration procedures, maintenance or cleanings have been performed as planned. Calculate, Graph and Send Data • Easily generate meaningful data - Identify trends faster by viewing or exporting the data for a selected time period as a table or as a graph. • Was there an unexpected or unintended spike in turbidity? Operators can add notes to any data point so that the “why” can be easily referenced in the future. • Quickly calculate important values, such as upper and lower control limits, and percent compliance over a selected time frame. User Security and Data Protection • Uses Bluetooth® Connectivity to communicate directly with a single sensor. Only users that are within a 30M radius of the PTV Sensor has access to the data via the app. • Set passwords - with two levels of access, users who do not need access to certain features or control settings can be prevented from accidently changing anything • Establish Criteria and protocols. Supervisors can easily set pass/fail criteria for verifications and calibrations, as well as set alarms and control other key settings such as Bubble Reject and Signal Averaging. ## Key features - Step-by-step illustrated instructions - Access to instrument history - Data calculation and graphing - User security with password protection - Bluetooth connectivity to sensor - Pro-tip information access ## Recent user reviews (1 of 1) All indexed reviews: https://appshunter.io/ios/app/aqualxp/id1214047349/reviews.md ### 1/5 — Needs Work *2019-06-23* The app makes acknowledging alarms etc a process that takes twice as long as it should. When finished with one turbidimeter and trying to communicate with a second, the app crashes and has to be reopened. Every. Single. Time. It’s trash. Fix it, please! **Developer response:** Thank you for the feedback! We are currently working hard to fix the app crashes in between connecting to devices. This is an issue that was introduced by iOS 12. Update: This issue has been address with app version 1.633, please keep an eye out for its release in the coming days. ## Frequently asked questions about AquaLXP ### What is AquaLXP used for?
