Area Monitor/Frisker Count Rate Meter

Victoreen® Model 190F



Model 190F shown with
optional GM Pancake Probe
(Model 489-110D)

Introduction

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

 
  • Adjustable Alarm
     

  • Backlit analog/
    digital display
     

  • Interchangeable
    probe adapter
    module
     

  • Multiple probe
    use
     

  • Redundant power supply
     

  • Available in SI units

 

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
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/hr R/hr
CPM CPS  
µSv/hr 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

Power requirements 9 VDC regulated power converter

Batteries Three 9 V batteries, 150 hours operation, automatically indicates when battery is low

Warm up time 15 second diagnostic check

Check source Natural uranium, mounted on the case

Environmental

Temperature range 14º to 140ºF (- 10° to + 60°C)

Relative humidity 0 to 95%, non-condensing

Construction Molded ABS plastic, splash-proof case. Probe fits into side-mounted ABS plastic probe holder with Velcro® straps

Dimensions 3.75 (w) x 9.2 (d) x 2.1 in (h) (9.2 x 23.4 x 5 cm)

Weight (without probe) 1.56 lb (0.70 kg)

Optional accessories

Infrared Communicator (Model 190-1A), additional features can be activated, such as Log Mode, Alarm Setpoint, Energy Specific Calibrations, and default setting changes. Features and pushbuttons can also be locked-out to set up the Model 190F in a user defined mode of operation

Note: The Model 190F Area Monitor and Count Rate Meter, with the customer selected probe is calibrated to NIST standards. The 190F and probe is calibrated in mR/h or μSv/h units as a standard. The end user may calibrate in additional radiation units using the 190-1A Infrared Communicator

Available model(s)

190F Area Monitor/Frisker Count Rate Meter

Tested. Meets applicable standards.
