6920V2-2 SONDE
Available Sensors Temperature, Conductivity, pH, ORP, one ion selective electrode (ammonium,
nitrate, or chloride), and Depth (shallow, medium, shallow vented). Two total
optical sensors (ROX Optical DO, Turbidity, Chlorophyll, Rhodamine WT, BGA-
PC, or BGA-PE).
Operating Environment Medium: fresh, sea, or polluted water
Temperature: -5 to +50  C for most sensors
Depth: 0 to 200 feet (61 meters)
Storage Temperature: -40 to +60  C for sonde and all sensors except pH , pH/ORP, ISE and optical
sensors
-10 to +60  C for pH, pH/ORP, ISE, and optical sensors
Material: Polyurethane, PVC, Stainless Steel
Diameter: 2.9 inches (7.4 cm)
Length: Approximately 18.25 inches (46.4 cm) with no depth, 19.63 inches (49.9 cm)
with depth
Weight: Approximately 3.74 pounds (1.7 kg)
Computer Interface: RS-232C, SDI-12
Internal logging
memory size: 384 kilobytes (150,000 individual parameter readings)
Power: 8 AA-size Alkaline Batteries or External 12 VDC
Battery Life: Approximately 32 days at 20 C at a 15 minute logging interval with ROX Optical
DO, another optical sensor (turbidity, chlorophyll, Rhodamine WT, BGA-BC, or
BGA-PE), temperature, conductivity, and pH active. Battery life is heavily
dependent on sensor configuration and is given above for a typical sensor
ensemble. If you have a different sensor configuration, set up your sonde for a
deployment in the Run|Unattended menu and check the projected approximate
battery life.
6820V2-1 SONDE
Available Sensors Temperature, Conductivity, Rapid Pulse Dissolved Oxygen, pH, ORP, three ion
selective electrodes (ammonium, nitrate, chloride), and Depth (shallow, medium,
shallow vented). One total optical sensor (ROX Optical DO, Turbidity,
Chlorophyll, Rhodamine WT, BGA-PC, or BGA-PE). Note that Rapid Pulse and
ROX DO sensors cannot be activated simultaneously.
Operating Environment Medium: fresh, sea, or polluted water
Temperature: -5 to +50  C for most sensors
Depth: 0 to 200 feet (61 meters)
