pHOptica™ is a pH measuring system which uses fibre 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 fibre-optic meter for pH measurements with miniature sensors.
• Two 12-bit, programmable analogue 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 coloured or photosynthetically active samples

pHOptica Mini system

The pHOptica micro system is a single channel pH system for use with fibre 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
