DIGITAL MICROR SURVEY METER by Ludlum Measurements

The Model 3019 is an ergonomically-designed, low-weight digital background survey meter used for background measurements of gamma radiation levels up to 500 µSv/hr (50 mR/hr). An internally installed Csl scintillator provides 175 cpm per µR/hr sensitivity. This instrument’s alarm set points can be designated through Setup Mode using the onboard keypad, or alternatively by USB connection via the optional software. Other features include a large, easily-readable LCD (liquid crystal display); an audio warning tone; and easy, intuitive design. Splash-resistant construction matched with a housing made of durable, high-impact plastic enables this instrument to be used indoors or outdoors. The padded handle is shipped pre-configured for datalogging operations with the built-in logging push button and warning light, making the device ready if the customer chooses to acquire the optional datalog software. Operators can access several setting adjustments, including calibration constant, dead time correction, efficiency, high voltage, high voltage current overload level, pulse threshold, response time (fast or slow), count time, operational modes (Rate, Max, or Count), and minimum and maximum display levels. The user may also set Primary and Secondary units, unit alarm levels, count units, count alarm levels, and zero pulse protection time limit. Zero pulse protection will warn the operator by causing a zero reading to flash and triggering an audible alarm after a user-selected number of seconds with no pulses from the detector. Another alarm, the sigma audio feature, assists search efforts by issuing an audible alarm when radiation levels outside set parameters are detected. An internal switch is used to enable or disable the front-panel setup feature to protect desired settings from inadvertent modification.

• Large Backlit LCD for Ease of Reading
• Autoranging - Hands Free
• Sigma Audio and Bright LED Simplifies Searching
• Light Weight and Ruggedly Built
• Splash-Resistant Construction for Outdoor Use
• 4-Button Intuitive Interface for Easy Operation
• USB Port
• Rate, Max, and Count Modes of Operation
• Reading within 10% of true value
• Built-in ambient light sensor automatically activates low-power LED backlight, unless internal dipswitch is set to continuous-On (will reduce battery life)
• User-selectable from 1 to 60 seconds, or Auto-Response Rate FAST or SLOW
• Alarm setpoints adjustable over the display's range (see manual)
• 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
• High count rate saturation protection prevents false display of lower count rates
• 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
• Employs first and second order corrections for extended performance
• Greater than 75 dB at 0.6 m (2 ft), approximately 4.5 kHz
• Approximately 750 hours of operation (as low as 100 hours with backlight configured for continuous-on), 16-hour low battery warning
• High-impact plastic with water-resistant rubber seals and separate battery compartment
• NEMA rating of 5x or IP rating of 53

Control:

• Press to turn ON
• Tap to acknowledge alarms and silence alarm tone
• Press to reset Sigma Audio alarm
• Hold for OFF
• NORMAL (count rate)
• MAX (captures peak rate)
• COUNT (user-selectable preset count time from 0 to 10 min.)
• Number of modes can be reduced in setup
• Turn “click” audio On/Off
• Turn Sigma Audio beep On/Off

• Very Sensitive Internal CsI Detector
• Large, Backlit, Easy-To-Read LCD Screen
• Auto-Ranging
• Rate, Max, and Count Modes
• Sigma Audio Mode
• Splash-Resistant Construction for Outdoor Use
• All Digital Calibration
• Lightweight yet Rugged
• Simple 5-Button Interface
