Rugged Digital Temperature Sensor with SDI-12 Interface,RS485 Modbus-RTU
The DigiTEMP is a high precision digital temperature sensor ideal for high-accuracy readings in water, soil, and air. It features fully-potted components, robust stainless steel housing, making the sensor ideal for harsh environments. The sensor is small enough to easily deploy through standard 1” (2.5cm) PVC conduit with 8” (20.3cm) factory bend corners. It also offers a loop hole which can be used to mount weights or pull the sensor through pipes or other small areas.
The SDI-12 output provides universal compatibility with any SDI-12-enabled data logger and low power applications, or use a RS-485 physical interface for applications that require long cable runs or many sensors.
