Multi-Parameter Sensors
The Greenspan multi-parameter range of sensors provides a choice f ombinations of water quality and level parameters to meet the majority of environmental monitoring requirements.
The technology employed in the design and construction of the sensors allows for long-term deployment with a minimum requirement for field visits.
All sensors have on-board data loggers and are capable of communicating data direct to your office PC from remote locations.
Linked to a rain gauge and auto-sampler, the sensors can provide complete site monitoring and the capture of critical events
Features
• All Multi-parameter sensors are provided with an on board data-logger with 0.5Mb memory upgradeable to 1Mb. Typically, with 1Mb of memory a four-parameter sensor can log 15 months data when sampling at 15-minute intervals.
• SDI-12 output available with CTDP300 and CS304 configurations.
• Double O-ring seals and moulded cable gland to ensure long-term reliability.
• Toroidal conductivity sensing technology eliminates electrode corrosion effects, guaranteeing long life and reduced field service.
• On-board microprocessor controlled temperature compensation and linearisation delivers accurate conductivity data normalised to 25°C. Alternatively, raw data may also be provided.
• Ceramic capacitor pressure sensing transducer offers unmatched reliability.
• Innovative optically isolated signal conditioning electronics ensure true and accurate pH readings at all times.
• Field proven gel-filled double junction pH electrode provides long-term stability.
• The DO membrane design is suitable for longterm deployment with minimal user intervention for cleaning and maintenance. Improved response time (T in 60 mins) when in minimum flow conditions (1mtr/min).
• Software calibration allows users to quickly and accurately recalibrate the sensor, eliminating the down time required when sensors have to be returned for factory calibration. Easy to use Windows based calibration software runs on a Laptop PC.
• A Detachable cable set is available as an option and this can be used on all Greenspan sensors.
