DatasheetCrowcon IQhub – Intelligent Test and Calibration Station for Gas Detectors
The Crowcon IQhub is a compact, automatic testing, calibration and charging station for portable gas detectors. Compatible devices can be configured, assigned, bump tested, calibrated and charged at one central station.
The innovative tubeless design simplifies operation and reduces maintenance requirements. At the same time, it supports reliable testing with a wide range of gases, including challenging gases such as ammonia (NH3) and hydrogen sulphide (H2S).
Fast Automatic Bump Tests and Calibrations
The IQhub is designed for fast and standardised testing procedures. A bump test can be completed in less than 10 seconds, while a full calibration takes less than 30 seconds. This makes the station particularly suitable for companies that regularly need to test and manage larger fleets of portable gas detectors.
Centralised Management with Crowcon Connect
In combination with Crowcon Connect, the IQhub supports centralised management of portable gas detection equipment. Test and calibration data can be assigned to individual instruments and used for fleet and compliance management.
Crowcon Connect supports the management and evaluation of information including:
- Alarm events
- Device usage
- Device configurations
- Bump tests and calibrations
- Compliance data
- Test and calibration certificates
Flexible Connectivity
The IQhub provides USB-C, Bluetooth®, Ethernet (RJ45) and NFC connectivity for communication and data transfer. NFC enables continuous bidirectional communication with the connected gas detector.
