pH-Optica Fiber Optic pH Meter, Use with Minisensors

Referenced measurements with single excitation.

Key Features

• pH readings using a single-channel, portable, fiber-optic meter with small sensors
• Two 12-bit, electrically isolated analog outputs with programmability
• A single electrically isolated external trigger input
• For functioning, a computer with an RS232 port is needed
• Utilize with minisensors, foils, and spots.
• pH measures that are non-intrusive and non-distortive
• The system does not contain the sensors

Benefits

• Software that is simple to use saves and displays measured values
• One computer can link to several pHOptica meters
• A temperature sensor is used to track temperature changes
• There is no requirement for a reference electrode

Applications for pHOptica Mini System

The pHOptica mini system is a one-channel pH system that may be used with foil and spot surface sensors, as well as fiber optic mini sensors, for applications such as:

• Non-intrusive and non-distractive pH measurements via the walls of the flask (cell culture)
• Monitoring the pH online using flow-through cells
• Measuring pH with a dipping probe

Mini Sensor Features

• The dipping sensor's OD is 4 mm.
• Gamma radiation sterilization of the pH sensor spots
• Based on 2 mm PMMA waveguides, the pH mini sensor meter measures pH.
• 0.1pH unit drift across 10,000 readings (4 days measurement in the 30 sec data update mode)
