Waterra-In-Situ - Leaders in water level and water quality monitoring instrumentation

Durable Dataloggers

Now we have been working with the In-Situ Inc. TROLL® range of water level instruments for several months some of their key features are being very apparent to both us and our clients.

We are particularly impressed by their versatilty (vented cable and absolute pressure options are available across the range), the detailed calibration record provided to customers with each logger, and their proven ability to operate accurately over a wide temperature range - unlike many competitor models which drift significantly in response to temperature changes.

It's all down to 4 factors:

• Most of the TROLL® products have a titanium casing. This use of high quality titanium in manufacturing makes the units inherently corrosion and chemical resistant - and far superior to coated stainless steel alternatives.


• Sensors are made of ceramics or titanium, which makes them particularly hardy and resistant to fouling. Further protection is possible with In-Situ anti fouling systems.


• Loggers are fully sealed unit, avoiding the problem of damage due to water intrusion frequently associated with non sealed alternatves.


• Batteries are guaranteed to last for 5 years when reading every 15 minutes. TROLL loggers use the same batteries as competitors who will not offer any guarantee on battery life despite making bold statements suggesting 10 year longevity!

The TROLL® range is suitable for a wide variety of groundwater and surface water monitoring applications.
