Personal Measurement Assistant Model PMA2100
Exclusively from Solar Light Company, the Personal Measurement Assistant Model PMA2100, an innovative concept of intelligent sensor detection and data processing. Add new sensors quickly without rebuilding your meter, purchasing a new one or compromising features such as: graphic display and data storage, complex processing algorithms, selectable units, averaging, tracking minima and maxima, dose integration, programmable alarm thresholds - all in a small pocket size device. Choose from an initial offer of detectors covering the entire UV and visible spectrum - with more to come.
Enjoy flexibility. By utilizing latest sensor technology and object oriented approach in its design the PMA2100 will support virtually any sensor that generates up to 4 analog signals. The detector setup and algorithms are encapsulated in the detector.
Secure your investment. Choose a meter that will serve you for years to come. Add new detectors as you need them. If an application requires special features the PMA2100 can be easily upgraded simply by loading new software from the PC.
Safeguard your data. The data collected by the PMA2100 are stored in a non-volatile memory that retains its contents for years.
Stay in control of your measurements. There is much more to an accurate measurement than just recording it's result. Along with the measured value the PMA2100 will automatically store or print other critical data including the sensor's serial number and calibration due date.
Don't change your habits. Instead tell the meter to display the results your way. The PMA2100's sensors are smart enough to remember the last configuration, including the units and values of alarm thresholds.
Features
Variety of detectors available. Many standard detectors are available off the shelf. Due to its novel features the PMA2100 allows us to interface custom detectors quickly and inexpensively.
Ease of use. The PMA2100 automatically configures itself for the new sensor when connected. No more entering programs and calibration factors. The detector setup and algorithms are encapsulated in the detector and the detector is ready to measure immediately after being connected.
Portability. The PMA2100 with its powerful features easily fits into the palm of your hand. Up to 2 detectors can be connected simultaneously via a 1ft/5ft retractable cable enabling measurements in difficult to reach places. Rechargeable batteries suffice for 30 hours of continuos operation.
Data logging. Up to 1024 data records can be stored in the internal non-volatile memory. The storage can be triggered manually or automatically in a user-set intervals (1 minute-2 hours). Uniform record structure for all detectors simplifies data management.
Traceability. Each data sample is accompanied by a set of auxiliary information such as: date, time, detector type and serial number, currently used units, user set scale factor, detector calibration due date and a set of flags indicating the state of the meter. This encourages an implementation of Good Laboratory Practices (GLP) and eases interfacing to Laboratory Information Management Systems (LIMS).
Noise immunity. The signal amplification is done inside the detector encapsulated in a metal enclosure. The signal is delivered to the PMA2100 through a shielded cable offering high immunity to EMI and ESD.
Automatic unit conversion. The measurement result can be displayed in one of many units customary for the particular measurement. A push of a button changes the unit selection. Custom units and conversion algorithms can be programmed to the detector on request.
Dose integration. A dose integration can be started from the keypad or remotely.
Computer interface. Connection to a PC through a serial interface (RS232) enables transfer of collected data. PMA Organizer, a Windows-based software automates data retrieval, archiving and presentation.
User defined alarms. An independent alarm can be set for the instantaneous value or integrated dose for each detector. The alarm settings are stored in the detector and automatically recalled when the detector is in use.
Isolated Digital Input/Output. A process can be controlled by the PMA2100 through the optically isolated digital I/O. The inputs can start or stop the dose collection while the outputs are triggered by the dose and value alarms. A control of the dose of radiation to a subject is one possible application. Power relay is available as an accessory.
