The Quanta is a complete system capable of monitoring
multiple water quality parameters simultaneously. Each unit is
custom configured to the parameters you want to monitor, and
can operate at depths up to 100 meters.
It has been designed for monitoring in rivers, lakes,
streams, oceans and everything in between. It can be used
in polluted or non-polluted water. When equipped with the
optional flow cell, it can be used to monitor water quality
parameters in ground water as well.
Streamline Measurement offers land-based and buoy-based logging and
communications systems for the Quanta and by utilising advanced
telecommunications technology, you can access your data
from anywhere in the world.
A Quanta system is composes of the Quanta
transmitter, which houses the sensors, the Streamline Measurement SDI-12 Micrologger (or the Quanta display for spot measurements), a power source (typically a 12V lead acid battery) and a connecting cable. At the heart of the Quanta is Hydrolab’s superior sensor technology. These sensors have been rigorously field-tested and are proven to deliver reliable water quality data.
Temperature; The Quanta is fitted with a high stability thermistor in a 316 stainless steel tube. It never needs calibration.
Dissolved Oxygen; is measured with field-proven Clark Cell technology which provides a continuous steady-state reading. It is low maintenance, easily and affordably cleaned and maintained with no need to recondition sensor.
pH; measured using a standard pH glass sensor and unique rebuildable reference electrode. The reference electrode is more reliable, lasts longer, is easier to maintain, and refills in seconds. There is no need to replace the sensor.
ORP; The Quanta uses the standard platinum electrode.
Specific Conductance; Measured using the standard four electrode cell methodology. The open cell design is easy to maintain and provides more reliable data. Air bubbles and sediment do not affect sensor.
Depth; The Quanta is fitted with a custom-made high stability
pressure sensor. _Two ranges are available; 0 - 25 meters and 0 - 100 meters.
Vented Level; The Quanta is available with 0.003 meter accuracy over the range of 0 - 10 meters. This accuracy is valid for the full temperature range, not just
at 25°C. The vent provides automatic correction for changes in atmospheric pressure.
Turbidity; Only Hydrolab offers the 4-Beam turbidity sensor, a fouling resistant
and accurate sensor. This accuracy is valid for the full temperature range, not just
at 25°C.
