| Fluke/Victoreen 190F Area Monitor/Frisker Count Rate Meter. |
 | 
Key FeaturesThe easy-to-use, auto-ranging 190F is compatible with GM detectors, neutron probes, proportional counters, and scintillation probes operating from 300 volts to 1,300 volts. Depending on probe selection, the 190F detects alpha, beta, gamma, x-ray or neutron radiation within an operating range of l µR/h (1 CPM to 1,000,000 CPM). The unit is available with either an MHV or a BNC connector. Visual indication of selected parameters, as well as measured values, are displayed on the analog/digital display. The 190F Area Monitor/Frisker Count Rate Meter, with purchased probe, is shipped calibrated and ready-to-use. Specifications 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 Temperature range -10°C to +60°C (14° F to 140° F) Relative humidity 0 to 95%, non-condensing Housing material Molded ABS plastic, splash-proof case. Probe fits into side-mounted ABS plastic probe holder with Velcro® straps Dimensions (WxDxH) 9.2cm x 23.4cm x 5cm (3.75 in x 9.2 in x 2.1in) Weight 0.70 kg (1.56 lb) Optional accessories 190-1A Infrared Communicator 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 190F in a user defined mode of operation. NOTE: The 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. |

GM probes for qualitative radiation detection - The Geiger-Mueller (GM) detectors fulfill a wide variety of radiation
measurement needs for alpha, beta, gamma and x-ray sources. Some probes are provided with a 360º shield to permit
discrimination between penetrating and non-penetrating radiation. The GM detectors have a field-proven design to ensure dependable performance, reliability and ruggedness. Standard MHV type connectors readily allow interchange of all detector probes. The life expectancy of the counters range from 108 total counts to unlimited life depending on the type of quench gas utilized. Enhanced sensitivity to low level alpha, beta, gamma and x-ray radiation is achieved when using the unique 489-110D Pancake GM Probe. The following probe selection guide lists various probes and suggested applications. Applications include nuclear medicine, counter top surveys, leakage detection from diagnostic x-ray and linear accelerators, geological surveys, scrap metal yards and unknown wells. Scintillation probes for quantitative radiation assessment (counts/minute). The scintiallation detectors are optically coupled to photomultiplier tubes, which are then both magnetically shielded with mu-metal and specially shock-mounted to provide trouble-free performance. The entire detector, crystal and photomultiplier, are secured in a sturdy cylindrical aluminum housing. Where appropriate, a thin window has been utilized to provide alpha or low energy gamma response. Applications outlined in this guide include nuclear medicine labs, HAZMAT spills, radiation safety office surveys, industrial hygiene, industrial x-ray manufacturing, and geological surveys. |
