Description
Seametrics T1 Offering both SDI12 and Modbus® interfaces, the Seametrics T1/T1Ris a smart choice for upgrading to digital and replacing your analog temperature sensors. The T1/T1R’s rugged construction of 316 stainless steel, fluoropolymer, and PTFE resists weathering and data interferences, making it safe for long-term deployment.
The T1 is easy to interface with SDI-12 recorders and can be daisy-chained on one cable up to 200 feet, making it a preferred choice for many environmental professionals with existing SDI-12 systems. The T1R is powered internally with two AA batteries.
Alternately it can be powered with an external auxiliary power supply for data-intensive applications. While most will use the T1R with our free, easy-to-use Aqua4Plus software, it is by no means limited to that software. You can use your own Modbus®RTU or SDI-12 software or logging equipment to read measurements, thus tying into your existing systems and databases
