1.3 Temperature

Levelogger Gold and Levelogger Junior, record temperature compensated water
levels. Groundwater and surface water temperature measurements are
particularly important in situations where temperatures may fluctuate
significantly, and when temperature is used in determining liquid level, viscosity
and hydraulic conductivity. Temperature monitoring is vital in the calculation of
certain temperature dependent contaminant reaction rates.
A Platinum Resistance Temperature Detector is used to accurately compensate
for temperature changes within the range of -10 to +40˚C. The Leveloggers
will record temperature in its thermal range of -20 to +80˚C, but outside the
range of -10 to +40˚C compensation will be less accurate. The Levelogger
Gold reacts very quickly to changes in temperature (<1 minute) to give high
accuracy. The thermal response time of the Levelogger Junior is 3-5 minutes.

1.4 Total Precipitation

The Solinst Rainlogger is designed to count the tips of an external tipping-bucket rain
gauge within a user defined sample interval and output the total rainfall over that
sample interval. The Rainlogger can store 40,000 readings. The Rainlogger is
designed to be compatible with the Solinst Levelogger series of products. The
Rainlogger is programmed and data viewed and exported using the Levelogger
Software from a PC, it can be communicated with using a Leveloader and can be
integrated into an STS Telemetry System.

1.5 Backwards Compatibility

The Levelogger Gold and the Software Versions 3.2.3 or higher are backward
compatible, with limitations. If a Levelogger Gold is to be used with the Leveloader I,
Leveloader II, a Protocol Converter or an STS or RRL Telemetry System, the
data logger must be programmed with the old Levelogger Version 2.03 Software.
Programming Levelogger Gold loggers using Version 2.03 Software limits the
capabilities of the Gold unit, to be the same as the older stainless steel Levelogger units.
If the user has a mix of Levelogger Gold and older units, they can use the Levelogger
Gold Software to program and read all the loggers. They will get the accuracy and
features inherent in the older stainless steel loggers, but will obtain the higher accuracy
and enhanced features and functions of the Levelogger Gold loggers.
