Name: Digital Measuring Computer Complex for Chemistry (Teacher Edition)
Brand: ULabs
Availability: InStock

A teacher set of eleven wireless standalone sensors that collect, process and visualise experimental data in real time during chemistry lessons in K-12 schools. Each sensor shows its reading on its own colour screen and sends data to a computer, mobile device or cloud service, where a digital course with an AI assistant helps students work with the results.

Specification

Purpose: teacher demonstrations, laboratory, practical and research work in the chemistry classroom
Configuration: teacher set — sensors for temperature, surface temperature, carbon dioxide, oxygen, dissolved oxygen, gas pressure, conductivity, pH, drop counting and optical properties of solutions
Number of sensors: 11 devices (10 types; gas pressure sensor supplied as 2 pcs)
Sensor type: wireless and standalone; a data logger or other analogue-to-digital converter is not required
On-sensor readout: own colour LCD screen, 1.8 in diagonal, showing the measured value at the moment it is taken
Data transfer: wireless, from several sensors at once, to a computer, a mobile device or a cloud service
Software: displays data as tables and graphs, exports data to spreadsheet editors and other programs
Interface language: Ukrainian by default, English available as an option
Digital course volume: 70 academic hours
AI assistant: integrated into the platform, built on retrieval-augmented generation
Licence (right of access): 12 months

Powered by AI

Data from the sensors reaches the platform automatically, with no manual entry, and is processed there by an AI assistant integrated into the learning management system and built on retrieval-augmented generation over a localised knowledge base aligned with the national curriculum of Ukraine. The assistant is a separate tool of the digital course and uses generative artificial intelligence.

AI Assistant Functions

Task selection: automated selection of research tasks and experiments matching the topic of the lesson
Methodological support: step-by-step description of the procedure for conducting experimental research
Error analysis: identification of typical student errors and personalised recommendations for correcting them
Adaptive difficulty: adaptation of task difficulty to different levels of student preparation
Reports and conclusions: support in compiling reports on research results and in structuring the conclusions drawn from experiments
Knowledge base: operation on a localised knowledge base aligned with the national curriculum of Ukraine
Licence: right of access to the software and materials valid for 12 months
Language: content, interface and learning materials in Ukrainian

Work with experimental data

Visualisation: presents the measured values as graphs and tables
Analysis: analyses the results obtained in the experiment
Patterns: identifies the relationships observed during the experiment
Reference comparison: compares the measured data with reference values
Interpretation: helps students form hypotheses, conclusions and interpretations within a defined 'knowledge corridor'

Assignments on the platform can be completed individually or in groups.

Digital Learning Materials

The digital course is a multimedia methodological guide for demonstrations, practical and laboratory work, hosted on the learning management system. It is an integral part of the set and is supplied with it; access is activated with the registration data included with the product.

Volume: 70 academic hours, compiled in line with the national curriculum of Ukraine
Research modules: structured modules in physics, biology, chemistry and STEM
Experiment scenarios: scenarios for running practical experiments
Laboratory instructions: step-by-step instructions for laboratory work
Video demonstrations: recorded demonstrations of experimental research
Interactive content: interactive exercises and assignments
Equipment alignment: every experiment is written for the sensors supplied, following the scheme equipment → method → learning outcomes
Teacher-specific scope: demonstration scenarios for the class, plus experiments the student set does not cover — titration with a recorded curve, gas composition in a closed volume and parallel experiments on two set-ups
Language: content and methodological materials in Ukrainian; platform interface multilingual, Ukrainian enabled by default and English available as an option
Licence (right of access): 12 months
