ArcAir is the app for Hamilton Arc sensors. It enables online monitoring and visualization of pH, dissolved oxygen, CO2, cell density, conductivity, and ORP sensors during biotechnological processes. With the ArcAir application, you can communicate wirelessly with up to 100 Arc sensors at the same time parallel to the process control system interface when an Arc Wi Bluetooth adapter is connected between the VP head of an Arc sensor and the VP sensor cable or the sensor has inbuilt Bluetooth functionality. Within the ArcAir application, Hamilton provides reporting and central data management of users, as well as validation reports for sensor calibration (excluding VCD sensors), verification, configuration, and communication. ArcAir embeds report’s electronic signatures, enabling paperless workflow. All of this complies with the GMP guidelines such as FDA CFR21 Part 11 or Eudralex Volume 4 Annex 11.

Verdict
The clearest difference is review sentiment: ArcAir at 100% against HOBOconnect's 8%. ArcAir also leads on rating (4.0 vs 2.2) and iOS requirement (11.0 vs 15.0). HOBOconnect's advantage is in-app purchases (none vs 2) and update cadence (every 6 weeks vs every 5 months). On price, ads and device support there is nothing between them.
