Stevens, with its Tyco / Greenspan strategic alliance, offers a product line of water quality analyzers, water quality multi-parameter sensors, and water quality single parameter sensor, all designed for long-term, unattended monitoring and analysis.
Multi-Parameter Sensors
Stevens range of single water quality parameter sensors, which are a cost-effective alternative solution to a multi-parameter sensor for those interested in only one or two of the following water parameters.
- Dissolved Oxygen
- Electric conductivity
- pH
- Turbidity /TSS
- Oxidation Reduction Potential (ORP)
Analyzers
Stevens / Greenspan analyzers perform chemical and physical water analyses automatically using standard laboratory methods for laboratory-comparable results. Chemical parameters include:
- Nutrients:
-Ammonia/Ammonium
-Nitrate
-Phosphate
- Total Phosphorous and dissolved reactive phosphate
- Total Nitrogen
- Total Organic Carbon
When combined with external-monitoring equipment, the analyzer can provide you with a comprehensive environmental monitoring system.
Software
Stevens' mission is to design and provide our customers with instruments that are easy to configure and use. An integral element towards this mission is enabling our sensors, loggers and telemetry modems to provide outputs that can easily be processed by other third party databases, data management, modeling, forecasting or GLS software programs.
Stevens provides various software programs under the following categories:
On-Line Data Management Service
Data Management Programs
Instrument Setup / Configuration Programs
Programs to Download
On-Line Data Management Services
Stevens offers two Internet Data Managment services on line:
- E-Monitoring.net
- GOESLink.com
Both these services collect the data from remote monitoring locations phone modem or other wireless telemetry procedures and permanently stores the data in a data base that can be accessed any time from any computer with Internet access. Advantages to these services include:
- Users need no customized software program.
- Users require no special or dedicated computer hardware and base station reception equipment.
- Users require no special training or knowledge of data management programs or hardware.
- Automatically incorporates a backup data management procedures for the users.
- Data security is enhanced with automatic off site storage.
Data Management Programs
Stevens offers the following Data Managment Programs for use on a lap top computer for field analysis, and for use as a base station management, control and analysis program for multiple montitoring locations:
- GOESLink with Microsoft SQL for Satellite DRGS
- DAQ Factory Data Acquisition and Control
- AquaGraph
- Logger Suite for PC and for PDA
- AxRead
Instrument Setup/Configuration Programs
For Stevens’s instruments, Stevens provides the following software programs for easy setup and configurations:
- GHT Set (for the Stevens GOES HDR Transmitter)
- Logger Suite (for the Stevens DOT Logger)
- AxSet (for the Stevens AxSys data logger)
- SmartComm (for the Stevens/Greenspan data logging pressure sensors and water quality sensors)
