Sensor stalk: Diameter 2mm, length nominally 200 mm.
Sensing
region near the tip of the stalk is the same diameter and flexibility as the rest.
Surface materials: 316 stainless steel, silicone rubber,
Teflon
(TM)
Battery life: >7 years
Position logging life: >7 years
Data memory: 256K Bytes battery-backed RAM, 30 K is
allocated to a 7 year "day log"
Light Measurement: Intensity of 470 +- 40 NM light over
a 5.5
decade range.
Temperature: -5 to +35 C, 0.2 C resolution and
accuracy.
Pressure (as depth): 0 to 510 m. Resolution 1M to 126M,
3M
beyond.
Two pressure histograms are kept, 1M resolution to 255M, and 3 M resolution to about 700 M, with the limit somewhat higher for some individual tags.
Each tag comes with a detailed calibration and final test report.
