Read full description

The DoserX application is designed to control and configure Aqua-Trend's SAMUDRA series multifunctional aquarium dispensers. The application works with the five-channel DoserX dispenser, and the three-channel DoserXs dispenser. DoserX is the sum of experience gained over 15 years by the first Polish manufacturer of aquarium dispensing equipment. The knowledge we gained, and the feedback from our customers, allowed us to build an aquarium dispenser that will meet the expectations of even the most demanding aquarists. This application will allow you to take advantage of all the functions that DoserX offers and will also help you in the daily care of your aquarium. Below you will find a description of some of the functions DoserX offers - Control operation of five (or three) precision peristaltic pumps: Schedule-based operation, manual switching of peristaltic pumps, rapid release of programmed doses, release of control doses. - Scheduler: An elaborate diagram with which you can easily program the dose release of each of the five ( or three) pumps. Thoughtful options for copying and transferring settings make it take just a few minutes to program the operation of all pumps. - Calibration: With the peristaltic pumps' calibration feature, you'll be sure that each released dose will contain the exact volume of liquid you programmed. - Calculation of consumption of pumping hoses and peristaltic heads. - Monitoring of fluid consumption: A function thanks to which you will always know when to refill the bottles with dispensed fluids. - Magnetic stirrer: Thanks to the operation of the magnetic stirrer you will be sure that suspensions and liquids containing solid particles (such as foods) will be dosed into the aquarium in the right way. - Temperature measurement: The temperature measured by the device is presented in the form of an easy-to-read graph containing historical measurements. - Temperature alarm: With DoserX, you will never miss a harmful rise, or drop in temperature. - Automatic refill with overrun alarm and operating time limit: A function that maintains a constant, safe level of water in the aquarium, in case of problems an appropriate acoustic alarm will sound and the topper will be turned off. - Aquarium maintenance logbook: With an extensive logbook, you will easily archive all activities, measurements and events in your aquarium. All entered data is presented in an easy-to-read graph that shows what changes have occurred in your aquarium over time. The application uses the BLE (Bluetooth Low Energy) communication standard in its operation.
