Short video · Russian
Presentation materials. The interfaces and values illustrate a use case, not an operating Citadex Engineering network. Platform and analytics functions are agreed as part of the project.
What the station measures
Based on the QuakeLogic technical proposal dated 24 September 2026. Specifications are confirmed for the selected configuration.
PM2.5 and PM10
Laser measurement of airborne particles. Ranges, sampling and data-processing requirements are agreed for the monitoring programme.
Measurement context
Wind speed and direction, air temperature, relative humidity and atmospheric pressure help interpret changes in pollutant concentrations.
From the station to the system
Local storage, remote diagnostics and resumed transmission after a connection outage. Software and integration scope are defined by the project.
Configuration and integration
| Measured gases | H₂S, O₃, NO₂, NH₃, CO, SO₂ |
| Airborne particles | PM2.5, PM10 |
| Weather parameters | Wind, temperature, humidity, pressure |
| Operating conditions | The proposal specifies −40…+60 °C and IP66 |
| Connectivity | 4G in the standard configuration; Ethernet/Wi-Fi and modem are confirmed per project |
| Power supply | 220 V ±10%, 50 Hz; backup power selected for the task |
| Backup runtime | The project proposal includes a UPS with at least 4 hours of backup |
| Formats | CSV/XLS as standard; XML/JSON through the QuakeLogic integration layer |
| Integration | API and connection to the customer’s system within the agreed scope |
| Maintenance | Calibration, filters, consumables and maintenance schedule are confirmed when ordering |
Video summary
An overview of the station, gas and particle measurement, weather module, centralised platform connectivity and possible analytics. The materials show a proposed station-network scenario; the device count and implementation conditions are not a published commitment by Citadex Engineering.
