KELLER ARC-1 Autonomous Remote Data Collector

The ARC-1 is the latest-generation data logger from KELLER, superseding the GSM-2 device. The unit remotely tracks pressure measurements and fill and water levels, and monitors limit values.

In the interests of compatibility, the ARC-1 incorporates the same functions as the GSM-2 but includes some new features including: ARC-1 communicates via the 3G or 4G mobile network; Micro SIM card; system status information has been supplemented by a moisture sensor; integration of a real-time clock to improve accuracy.

At 48 mm in diameter, the ARC-1 can be easily placed into the top of a 2″-wide sounding tube, standard in the groundwater-measuring industry. Complete with energy-efficient electronics and a premium-quality lithium battery (3.9 V/32 Ah), the logger can transmit the results of 24 measurements every day.

DataManager software covers the key functions of a monitoring, collection, control and organisation. Third parties can access the measurement data by means of various export and internet functions for integration into their own data collection systems.

KELLER’s Kolibri Cloud offers access to measurement data with a personal login and SSL encryption. Measurements can be displayed as graphs and the export function allows download of data as Excel or CSV files.
