The Model 3019 is a portable and versatile instrument with an internal detector used for background measurements of gamma radiation levels up to 500 µSv/h (50 mR/hr). The internal CsI scintillation detector has a sensitivity of 175 cpm per µR/hr. It features a large, easy-to-read LCD screen and audible alarms and is controlled using a simple five-button interface. The meter body is made of high-impact plastic and splash resistant construction allows the instrument to be used outdoors.

Three modes of operation are available - RATE, MAX, and COUNT - which can be selected by pressing the MODE button. Measurements can be collected in two sets of units (primary and secondary) for RATE and MAX modes in cps, cpm, mR/h, or µSv/h units. The user can switch between the two sets of units by pressing the UNITS button. A sigma audio mode can be enabled that allows the user to find small increases above the background radiation level. When enabled with the optional Lumic Data Logger Kit (see Options), data can be logged in any of the operational modes using the LOG button on the handle. Up to 1000 data points can be stored internally.

Instrument setup can be done either through the front-panel controls or via the Lumic Calibration Kit (see Options). The Model 3019 is shipped ready to use with batteries and calibration certificate.

Note: While the detector used in this instrument is sensitive and is often used for detection of near-background levels of radiation, its nonlinear energy response means that dose and exposure measurements may be over/underreported. (See graph below.)

Specifications

Detector (D x L)	Internal CsI scintillator, 2.5 x 1.9 cm (1 x 0.75 in.)
Sensitivity	175 cpm per µR/hr
Energy Range	Nonlinear (see Energy Response Curve in the Graphs tab)
Linearity	Reading within 10% of true value
Display	3 digit LCD with large 20 mm (0.8 in.) digits. Units: (k)cps, (k)cpm, (µ)(m)R(/h), (µ)(m)Sv(/h) Indicators: bar graph, MAX, ALARM, USB, audio, low-battery.
Detector Range	Background to 500 µSv/h (50 mR/hr)
Backlight	Built-in ambient light sensor automatically activates low-power LED backlight, unless internal dipswitch is set to continuous-On (will reduce battery life)
User Controls	ON/OFF: Extra-long press to turn ON; short press to acknowledge alarms; extra-long press plus 3 seconds to turn OFF UNITS: Short press changes the units between count rate, dose/exposure, or disintegration, an extra-long press to change count time in COUNT mode AUDIO: Short press to adjust audio level MODE: Short press alternates between modes: RATE (displays count rate), MAX (captures peak rate), and COUNT (captures rate or dose readings for a user-selectable preset count time from 0 to 10 min.) LOG: Short press to log current display (requires Lumic Data Logger Kit, see Options) or initiate count in COUNT mode
Data Logging	Can store up to 1000 data points internally. Requires Lumic Data Logger Kit (see Options).
Response Time	User-selectable from 1 to 60 seconds, or Auto-Response Rate FAST or SLOW
Alarms	Two adjustable count rate, exposure/dose, and count alarm setpoints adjustable over the display range (see manual)
Sigma Audio Mode	Alarm that allows user to find small increases above the background radiation level. The instrument will beep whenever it measures a rate that exceeds a threshold rate above the measured background rate.
Overload Protection	High count rate saturation protection prevents false display of lower count rates. "OL" will appear on the display and an audio warning will be triggered.
Loss of Count Protection	After a user-settable time interval (default of 60 seconds) of no pulses from the detector, unit will flash a zero reading and the alarm audio will be triggered
Dead Time Correction	Employs first and second order corrections for extended performance
Overrange	If the reading should exceed the predefined detector range, the instrument will flash a maximum reading and trigger an audio warning.
High Voltage	400 to 1500 Vdc
Threshold	-20 to -100 mVdc
Audio	Approximately 4.5 kHz, click audio greater than 65 dB at 0.6 m (2 ft), alarm audio greater than 72 dB
