TROLL® Shield

Product Details

When using the TROLL Shield anti-blocking system in coastal environments and high pollution places, it can effectively prevent the Aqua TROLL instrument and the conductivity cell from being blocked. Extend deployment time by more than 6 weeks. And can improve the accuracy and performance of the instrument. Copper mesh protection on Aqua TROLL 100 and 200 200 equipment. Use copper cone caps on Aqua TROLL 200. For best performance, replace every six months.

TROLL® Shield

No liquid freezing in temperature range

Typical battery life is factory calibrated during use, and temperature range depends on field conditions.

1 reading = date / time plus all available parameters for scanning or recording from the device.

1 data record = date / time plus 3 parameters of the record (no line feed)

When using linear averaging or event recording mode, an external power supply or battery box is recommended.

Parameters derived from temperature and actual conductivity range at 25 ° C 5 -100000 µS / cm Accuracy is ± 0.5% of reading +1 µS / cm

Derived from standard method 2510B

Defined in Practical Salinity Scale 1978; Standard Method 2520B

Real-time liquid level compensation based on water density

4-20 mA output accuracy term: ± 0.25% FS

Calibrates the pressure range throughout the factory.

Calibrates pressure and temperature ranges throughout the factory.
