Fluke Biomedical / Victoreen model 190I Survey Meter
The
Victoreen Model 190I is a Geiger-Mueller (GM) based survey meter operating with
an internal detector. The Model 190I is calibrated in mR/h or μSv/h. It also
accumulates dose and time in the integrate mode. The Model 190I features several
user-selectable parameters entered via the top panel push buttons or via
computer through an optional Model 190-1A Infrared Communicator.

Dimensions
2.6 (w) x 2.0 in (h) (6.6 x 5.1 cm)Analog scale (bar graph) 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 0.000l to 1 million (dependent on the activated units)
Alphanumeric display 16 character display shows digitized average on the bar graph value It displays operational units such as radiation unit changes, response time changes, data, and labels
Pushbutton controls
Mode Toggles and selects rate units:
μR/hr, mR/hr, R/h, CPM, CPS, μSv/h, mSv/hand the complementary units in the integrate mode:
μR mR, R CTS, μSv, mSv,
with the integrated time value in seconds.Log Logs 211 data points and sequentially labels data points.(Data retrieval requires the Model 190-1A Infrared Communicator)
Rate/Integrate Toggles between rate and integrate
Response time Toggles and selects: 24 seconds, 12 seconds, 6 seconds, or 3 seconds response time during operation
Audio Turns audio on and off. Acknowledges alarm
Light Turns back light ON for a preset time
Note: Using the Infrared Communicator, default settings can be programmed into the Model 190I. Features and push buttons can also be locked out to set up the Model 190I in a user-defined mode of operation
