Fiber Optic pH Meter, Use with Minisensors

Features

• 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
• Use with Minisensors, foils and spots
• Non-invasive and non-distractive pH measurements
• The sensors are not included within the system

Benefits

• 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
• No reference electrode is needed

Applications pHOptica Mini System

The pHOptica mini system is a one channel pH system for use with fiber optic mini sensors, foil and spot surface sensors for applications like:

• Non-invasive and non-distractive pH measurements from outside through flask walls (cell culture)
• Online pH monitoring by flow through cells
• Dipping probe pH measurement

Mini Sensor Features

• OD of the dipping sensor is 4 mm
• Sterilization of the pH sensor spots via gamma radiation
• The pH mini sensor meter is based on 2 mm PMMA waveguides
• Drift of 0.1pH units for 10,000 measurements (4 days measurement in the 30 sec data update mode).
