pH OPTICA

A novel fiber oprtic pH system
FEATURES
pHOptica™ is a pH measuring system which uses fiber optic sensors and patented DLR technology. This method allows referenced measurements with single excitation to be implemented.
Features of pHOptica Meter
• Single-channel, compact, easy to transport fiber-optic meter for pH measurements with miniature sensors.
• Two 12-bit, programmable analog outputs, with electrical isolation.
• One external trigger input, with electrical isolation.
• Computer with RS232 interface required for operation.
• User-friendly software saves and visualizes measured values.
• Several pHOptica meters can be connected to one computer.
• Temperature variation is recorded using a temperature sensor.
Features of pH optical sensors
• No reference electrode is needed
• Immune to electrical interferences and magnetic fields
• Low drift
• High spatial resolution due to small tip size
• Measurement in very small sample volumes
• Additional optical isolation of the sensor tip is available for measurements in colored or photosynthetically active samples
pHOptica Mini system
The pH Optica micro system is a single channel pH system for use with fiber optic mini sensors, foil and spot surface sensors. The applications include:
• Non-invasive and non-distractive pH measurements from outside through flask walls (cell culture)
• Online pH monitoring by flow through cells
• Dipping probe pH measurements
POF Coated with a pH-Sensitive Foil—Small and robust pH dipping sensor; no reference electrode needed.
Flow-Through Cell with Integrated pH Sensor—On-line monitoring; can be easily connected via Luer-Lock adapters.
Planar pH Sensitive Foils and spots—non-invasive and non-destructive measurement from outside through the wall of the flask; online monitoring.
