Case Studies
Overview
Manta+ water quality sondes are suitable for use in any natural water from -5°C to 50°C. It can be used as an unattended logger, used for spot testing and profiling with use of a tablet / PDA or installed with wireless telemetry systems.
Ideal applications for our water quality sonde include groundwater interaction, saltwater intrusion, surface water, reservoir and lake monitoring, estuary monitoring, watershed and source water protection, beach monitoring, storm water runoff, NPS monitoring, NPDES discharge, wastewater influent, effluent, vertical profiling, process water and aquaculture.
Different sizes of sonde are available depending on which sensors the user intends on installing. The Manta + sizes (outside diameter)available are 1.95 inches, 2.45 inches, 2.95 inches, 3.5 inches and 4 inches. All sizes are 19 inches in length including the weighted sensor guard and cable locking sleeve.

Sensor Details:
Optical Dissolved Oxygen Sensor
The optical dissolved oxygen sensor has no replaceable membranes or caps and requires no circulator. It provides exceptional accuracy and uses luminescent dissolved oxygen technology. It is insensitive to hydrogen sulfide (H2S) compared to polargraphic DO sensors and is not damaged by sunlight.
Turbidity Sensor
The turbidity sensor is highly accurate up to 3000NTU's. It has a self cleaning wiper that is user programable up to 5 wipes to remove biological growth or debris.
Chlorophyll a Sensor
The Chlorophyllsensor accurately measures in 3 ranges from 0.03 to 500 ug/L. It has ambient light and turbidity rejection circuitry and fast response time and compact design. An adjustable secondary standard is available for calibration and quick check.
Blue-Green Algae Sensor
The Blue-Green Algae sensor accurately measures in 3 ranges from 0 - 2,000,000 cells/mL Cyanobacteria (phycocyanin or phycoerythrin). It identifies potential algae blooms and provides substantial cost savings by eliminating cell counting.
Rhodamine WT Sensor
The Rhodamine WT Sensor measures accurately in 3 ranges from 0.04 to 1000 ppb. It is available with a secondary standard for quick and accurate calibration. Accurate readings and a fast response time are ensured with its ambient light rejection and fast response time. Small sample size volume design and high quality optics provide turbidity rejection
Depth
Depth sensors are available in 5 ranges from 0 - 200 meters in absolute or vented. It has automatic temperature and salinity compensation.
Temperature Sensor
The temperature sensor is a 30k ohm thermistor and has a 316 Stainless Steel housing. The temperature sensor is used to provide compensation for Specific Conductance, Dissolved Oxygen, pH, and Ion Selective Electrodes.
pH Sensor
The pH sensor is easily maintained. It has a rebuildable reference with PTFE/FEP Junction so there is no sensor to replace.
Conductivity Sensor
A very accurate sensor for measuring conductivity, specific conductance, salinity and TDS. It requires virtually no maintenance and is accurate up to 100,000 uS/cm. It automatically compensates temperature.
Ammonium
The Ammonia Ion Selective Electrode with replaceable plasticized tips and has a maximum depth of 25 meters. It provides automatic calculation of ammonia and total ammonia concentrations. It is designed for agricultural industry and fertiliser runoff in fresh water. Ammonia ISE's will not work in sea water and interfering ions will effect reading.
Chloride
The Chloride Ion Selective Electrode with replaceable plasticized tips and has a maximum depth of 25 meters. It is ideal for measurement of saltwater intrusion or as an effective tracer for pollution.
Nitrate Ion Selective Electrodes
The Nitrate Ion Selective Electrode with replaceable plasticized tips and has a maximum depth of 25 meters. It provides automatic correction of temperature and automatic compensation for ionic strength concentrations.
