South Fork Instruments provides superior quality NIR probes and housings for applications of all scales and difficulties.
Too often, manufacturers and processors tolerate the high costs resulting from sensors which are fragile and short-lived, as well as semi-automated and automated systems which fail to deliver on their promises. South Fork Instruments specializes in providing sensors and housings which are designed specifically for clean-in-place (CIP) and steam-in-place (SIP), biotech applications, energy production and wastewater treatment.
We can accommodate the demands of your applications, allowing you to better optimize and automate your processes, reducing your overhead costs and increasing your profitability.
Whether you are seeking sensors which have the highest possible surface quality for pharmaceutical applications, or been designed to meet the hygiene guidelines governing food/beverage processors and manufacturers, or utilize high-quality plastic or stainless steel to ensure safety and durability, South Fork Instruments can deliver the measurement solutions you need.
EXNER EXSPECT NIR PROCESS PROBES
EXspect probes are manufactured from 316L stainless steel to the highest standards and have sapphire optical windows for durability and resilience. A touch screen display allows for setup and continuous indication of process turbidity value. EXspect probes are installed inline using a sanitary metal to metal sealing method, removing the need to periodically replace elastomer seals. For installation, a range of fittings are available to facilitate easy implementation in your plant.
Expect sensors have the following exceptional features:
- Compact design with integrated electronics and touch screen display
- Resilient sapphire windows
- Hygienic design – suitable for CIP/SIP
- LED NIR source guarantees steady and long-life signal
- Integrated digital and analog output
- Intuitive configuration
- Process monitoring and documentation
- Liquid free calibration and testing using EXcap solid state reference filters
EXNER EXPLORE PROCESS SENSORS
EXplore sensors are compact and provide continuous turbidity measurement at a very economical price point. Used for applications such as phase separation/product change detection and filtration monitoring, hygienic EXplore sensors are process color independent and provide a high level of accuracy and repeatability. Designed for integration into a supervisory control system, sensors have a 4 – 20mA output.
Expect sensors have the following exceptional features:
- Compact design
- Resilient sapphire windows
- Hygienic design – suitable for CIP/SIP
- LED NIR source guarantees steady and long-life signal
- Integrated analog output
- Factory calibration – plug and play
- Liquid free testing using EXcap solid state reference filters
EXNER EXCAP CALIBRATION ACCESSORIES
Make calibration checking and verification easy using EXcap solid state calibration reference standards. EXNER calibration standards are available for both Absorbance and Backscatter technology instruments with a range of different values to ensure that probes and sensors are working to specification.
Simple to use, these reference materials are supplied in a protective case. Each standard is permanently marked with its value. Each is put over the active sensor interface and the subsequent instrument response checked to confirm operation and compliance.
