The ISA and BlueScan – UV/Vis Spectrometer Systems are capable of simultaneously detecting multiple parameters. With the corresponding calibration formulas, it is possible to calculate up to 99 different parameters. This is a standard function of the ISA and BlueScan – UV/Vis Spectrometer Systems.

The Calibration Monitoring feature provides a real-time evaluation of the trustworthiness of measurement readings by means of a Spectral Quality Index (SQI). The SQI indicates the validity of the calibration. Thereby it is possible to determine how well the calibration fits to the current water matrix and to automatically select the most suitable calibration at all times. With this unique feature it is possible to obtain an on-line quality detection of the spectrometer results and ensure the proper operability of the system.

The ISA and BlueScan – UV/Vis Spectrometers feature an integrated and automatically controlled pressurised air flushing for the cleaning of the optical windows. No mechanical parts protrude from the measuring head, which eases the installation in armatures and prevents the settling of dirt particles on the optical windows. With the pressurised air flushing the service expenditure can drastically be reduced.

The measurement heads of the ISA and BlueScan UV/Vis Spectrometer systems are ATEX certified and allow for the installation in potentially explosive atmospheres.
The measurement heads fulfil ATEX class III as standard. Optionally, ATEX class II is available.

With the help of the flexible communication possibilities of the BlueBox-System it is possible to transmit events locally or via telephone, network, mobile network, and satellite, if required through redundant paths, in a swift and reliable manner. All usual services like SMS, email, FAX and network protocols are available for the transmission. Response times for alarms and events can thereby be minimized and the reliability of operation can be optimized.

The BlueGate cloud data service automatically backs up all data and provides remote access via any web browser. The service offers a live data view, visualisations, and the and ability to export all measurement data. BlueGate also allows to set up alarms such as notifications for the exceedance of thresholds. All communications over public networks between BlueBox – BlueGate – and customer systems are encrypted.

The measurement head of the ISA – UV/Vis Spectrometer allows for an infinitely variable adjustment of the optical path length between 0.5 to 20 mm, which is a unique feature of the ISA Spectrometer. The optical path length of the BlueScan measurement head can be adjusted in discrete steps between 1 to 30 mm. The path lengths can be changed directly in the field by using a simple screwdriver. The adjustment of the measuring path is an imperatively necessary feature for optimal adaptation to the local specific water matrix.

The measuring head features an extremely high-temperature durability of +80 °C (for short periods, up to +110 °C). This substantially extends the range of applications, particularly for industrial implementations. The temperature insensitivity of the ISA and BlueScan is an advantage for cleaning and sterilization of the probe head. Since there are no electronic components in the measuring head, temperature influences (drift) on the electronics, UV/Vis lamp, and Spectrometer unit are eliminated.

The UV/Vis Spectrometers do not require any reagents or other consumables and can be operated maintenance-free except for necessary cleaning on location (dependent on the installation). The calculated life-time of the flashbulb is > 10 years. In the case of a defect, service on location is possible because all electronic components are external to the submersible probe.

The robust design of the ISA and BlueScan – UV/Vis Spectrometer Systems features a saltwater resistant measurement head that is made from high-quality stainless-steel (1.4404). Optionally, the measurement head is also available in titanium.
Furthermore, there is no electrical connection between the measuring head and the electronics. The separation prohibits etching due to the occurrence of corrosion currents between the measuring head and medium.

Individual components can easily be linked, which allows for the expansion of the system. Through the use of a field bus system (CAN bus), the ISA and BlueScan measurement systems can be extended at any time with other sensors and actuators. The systems allow the management of up to 200 sensors and actuators. Furthermore, the spectrometer systems feature all of the usual interfaces and protocols to communicate with other PLC or SCADA systems.

GO Systemelektronik offers open-access to all settings and calibration parameters of the system. The calibration parameters are disclosed and accessible for the customer. Thereby, the user is given complete control over their application and can make full use of the calibration functions. The customer can obtain the necessary software tools to calculate calibration functions. Specially tailored chemometric software allows for the simple production of individual calibrations, even for difficult and complex tasks.

A connection via internet or mobile networks facilitates the transmission of measurement data and results at any time and allows for remote access and control of the system. Thereby it is possible to change settings or transmit calibrations remotely.
