For years, KELLER’s GSM-2 has provided a simple way of ­remotely tracking pressure measurements, fill and water ­levels, and monitoring limit values. Now, this proven data logger with remote data transmission unit has been upgraded and given a new name: ARC-1, the Autonomous Remote Data Collector.

The ARC-1 incorporates the same functions as the GSM-2 but also includes some new features:
• Communication via mobile network 3G
• Micro SIM Card
• Moisture sensor
• Real-Time Clock

More information on the replacement can be found on the product site of ARC-1.
