Operating ranges Dependent on selected probe
Toggles and selects rate units μR/hr, mR/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 typical energy dependence.
Accuracy is probe dependent
Adapter module Contains calibration data and high voltage settings
for a specified probe. The module is available with an MHV
connector
Note Additional adapter modules can be purchased for use with
multiple probes: specify Model 190060 for MHV 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 190 Survey 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 190 with multiple probes
for survey work
Log Logs 211 data points and sequentially labels data points. (Data
retrieval requires the Infrared Communicator, Model 190-1A). With the
communicator, alphanumerics up to 16 characters can be programmed
into the Model 190 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
Battery condition Automatically indicates when battery is low
Power requirements Four 9 V batteries, 200 hours operation
Warm up time 15 second diagnostic check
Check source 0.064 μCi check source,
2 x 2 yellow card

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 190 in a user defined
mode of operation
Note The Model 190EX Survey and Count Rate Meter with pancake probe is
calibrated to NIST standards. The 190 and probe are calibrated in mR/h or μSv/h units as a standard. The Model 190EX unit pancake probe is not
weatherproof. The end user may calibrate in additional radiation units using
the Infrared Communicator, Model 190-1A.
