certified reference
*Note: The product line offers patented ABC Logic™ software
for self correction of drift to better than ±20 ppm per year. The system is
virtually free of maintenance and typically has a lifetime of more than 10
years.

Installation Kit
Response Time
Included with the transducer are wire nuts, mounting screws and
installation instructions.
Sampling Rate
