Benefit from the protection of the PetriSense® Fixed alarm and monitoring unit, with its 35 mm petri dish sized sensor, in a variety of laboratory equipment.
The New PetriSense® Fixed alarm unit provides continuous protection by monitoring CO2 and hence related pH in a variety of laboratory equipment.
The PetriSense® Fixed is easy to install in various types of laboratory equipment without expensive retrofit or modifications.
PetriSense® Fixed can be used as a standalone alarm unit or as part of a comprehensive alarm system, using the 4-20mA or volt free relay outputs to connect to the existing laboratory alarm system, providing 24 hour protection and alerts.
PetriSense® Fixed uses the established relationship between CO2 and pH to provide reproducible indications of pH culture conditions allowing early intervention to correct potential damaging changes in pH. Waiting for changes in pH may be too late.
The PetriSense® Fixed unit is programmed to take into consideration the buffering effect of the media providing real time information.
PetriSense® Fixed removes the need for the lengthy and costly daily calibration and sample preparation of other methods of pH monitoring.
- Easy to Install - Fits easily into a variety of laboratory equipment
- Adaptable - Use as a standalone alarm unit or as part of a more comprehensive laboratory alarm system.
- Reliable - Provides continual rather than point in time readings
- Peace of Mind - Monitoring CO2 provides early warning of potentially damaging changes in pH
- Protective - Provides 24 hour protection rather than intermittent readings.
PetriSense® Fixed Alarm Unit is supplied with software application for configuration and calibration of the alarm unit.1 Configuration for both media buffer parameters and alarm limits is available via this software.
PetriSense Fixed units are supplied with both standard volt-free relay outputs and 4-20mA, enabling connection to any laboratory alarm system which accepts these inputs. Alternatively the unit will operate as a standalone alarm unit providing audible and visual notification if limits are exceeded.
Weekly calibration of the unit in air is recommended and can be performed without connection to the calibration software.
