Features
The Model 190F Area Monitor/Frisker Count Rate Meter is compatible with GM detectors, neutron probes, proportional counters, and scintillation probes operating from 300 to 1300 volts. Depending on probe selection, the Model 190F detects alpha, beta, gamma, neutron, or x-ray radiation within an operating range of 1 μR/h to 1 R/h or 1 CPM to 1,000,000 CPM. The unit is available with either an MHV or a BNC connector, to provide the user with versatility in probe selection. Visual indication of selected parameters, as well as measured values, are displayed on the analog/digital display. The Model 190F Area Monitor/Frisker Count Rate Meter, with purchased probe, is shipped calibrated and ready-to-use.
Applications
The Model 190F Area Monitor/Frisker Count Rate Meter is an easy to use instrument with error-free visual indication and auto-ranging. This instrument is designed to meet the high technology requirements of Health Physics, Medical Physics, and Non-Destructive Testing applications.
Features
- Adjustable Alarm
- Backlit analog/digital display
- Interchangeable probe adapter module
- Multiple probe use
- Redundant power supply
- Available in SI units
LCD display readout
- 2.6 in wide (6.6 cm) x 2.0 in high (5.1 cm)
- Analog scale has fifty-one elements arranged in a radius arc. Each element represents 2% of full scale. Scale markings are 0, 2, 4, 6, 8 and 10. Scale length is 2.2 in (5.6 cm)
- Scale multiplier is 0.0001 to 1 million, dependent on probe selection and the activated units
- 16-character alphanumeric display shows digitized average of the bar graph value. It displays operational units such as radiation unit changes, response time changes, data and labels
Pushbutton controls
- Light – Activates a background light for a preset or indefinite amount of time
- Mode – Rolls through and displays the available units for the selected mode of operation
- Log – Enters and sequentially labels the displayed data into a data log
- Rate/Integ – Allows the user to select the mode of display
- Resp – Time Rolls through and displays available response times (3, 6, 12 and 24 seconds) for user selection
- Audio – Allows the user to turn the audio indicator on or off
Specifications
Operating ranges (dependent on selected probe)
Toggles and selects rate units:
µR/hr, mR/hr, R/hr, CPM, CPS, µSv/h, mSv/hr, DPM, Bq/cm2, µCi/cm2
and the complementary units in the integrate mode:
µR, mR, R, CTS, D, µSv, mSv, Bq, µCi
with the integrated time value in seconds.
Accuracy
Within 10% of reading between 10% to 100% of full scale indication on any range, exclusive of energy dependence. Accuracy is probe dependent
Detector
Accepts GM detectors, neutron probes, scintillation probes, and proportional counters operating at high voltages between 300 and 1300 volts
Adapter module
Contains calibration data and high voltage settings for a specified probe. The module is available with an MHV or a BNC connector. Specify the type of connector with order
Note: Additional adapter modules can be purchased for use with multiple probes
Specify Model 190060 for MHV adapter module
Specify Model 190070 for BNC adapter module
By using multiple replaceable probe adaptor modules, each module can be assigned to a specific probe. The module’s EEPROM stores the calibration factors for a specific probe. When plugged into a Model 190F Area Monitor and Count Rate Meter, it automatically sets the high voltage and activates the calibration data set for the specific probe. By using modules married to specific probes, the user has the convenience of using only one Model 190F with multiple probes for survey work
Log
Logs 211 data points and sequentially labels data points. (Data retrieval requires the Model 190-1A Infrared Communicator). With the communicator, alphanumerics up to 16 characters can be programmed into the Model 190F to name the locations of individual data points to be collected. The location name is displayed when the Log button is pressed. Press the Log button again, and the data point is stored
