RX3000

The HOBO RX3000 is Onset’s next-generation remote data logging station that provides instant access to site-specific environmental data anywhere, anytime via the internet. The new station combines the flexibility and sensor quality of more expensive systems, an onboard LCD display, and the convenience of plug-and-play operation. The RX3000 has three configurable systems, that can be configured below, that consist of the following part numbers: RX3001-00-01, RX3002-00-01, and RX3003-00-01.

S-SMC-M005

This affordably priced soil water content sensor offers a two-tine design for easy installation. In addition, the EC-5 is a smart sensor, which allows users to launch monitoring systems quickly, easily, and affordably. Since HOBO data loggers recognize this sensor, no complicated programming or setup is required. The EC-5 integrates with the field-proven ECH2O™ Sensor and a 12-bit A/D; and provides ±3% accuracy in typical soil conditions, and ±2% accuracy with soil-specific calibration. Readings are provided directly in volumetric water content. This sensor is designed to maintain low sensitivity to salinity and textural effects.
