FITUR BARU RANGER :

DENGAN FITUR TERBARU KINI SMARTPHONE ANDA BISA TERHUBUNG DENGAN SURVEYMETER DIGITAL RANGER

Radiation Alert Ranger

• Small, handheld, microprocessor-based instrument
• Excellent sensitivity to low levels of Alpha, Beta, Gamma, and X-rays
• Backlit digital display
• Red count light
• Audible Beeper that sounds with each count detected, providing instant indications of the radiation level.
• Selectable alert levels
• Adjustable timer for performing Timed Counts
• Built in efficiencies for common isotopes to calculate activity in Bq and DPM. (Important: The Ranger does not identify isotopes - to use this feature, you must know the isotope in advance).
• Internal memory, data logging, and USB connectivity
• Free Observer USB Software to download your data, set computer alarms, and calibrate your instrument!
• Optional wipe test plate for swipes.

SPECIFICATIONS

DETECTOR

Internal Halogen-quenched, uncompensated GM tube with thin mica window, 1.4-2.0 mg/cm² areal density. Effective diameter of window is 45 mm (1.77 in.).

OPERATING RANGE

mR/hr - .001 (1µR) to 100 CPM - 0 to 350,000 µSv/hr - .01 to 1000 CPS - 0 to 5000 Total Counts- 1 to 9,999,000 counts

Accuracy (Referenced to Cs137) Typically ±15% from factory, ±10% with NIST Source Calibration

ENERGY SENSITIVITY

Detects Alpha down to 2 MeV. Detects Beta down to .16 MeV; typical detection efficiency at 1 MeV is approx. 25%. Detects Gamma down to 10 KeV through the detector window. 3340 CPM/mR/hr (¹³⁷Cs). Smallest detectable level for ¹²⁵I is .02 µCi at contact.

BUILT-IN EFFICIENCIES

Sulfur (³⁵S), Strontium (⁹⁰Sr/y), Cesium (¹³⁷Cs), Phosphorus (³²P), Carbon (¹⁴C), Iodine (¹³¹I), Cobalt (⁶⁰Co), and Alpha

SELECTABLE ALERT SET RANGE

mR/hr .001 - 50 and CPM 1 - 160,000. Pulsating beeper sounds the alert. Adjustable alert levels are used for mR/hr / CPM, and µSv/hr / CPS. 70db @ 1m. Alarm will sound when in Timer Mode when set alarm threshold is reached.

ANTI-SATURATION

Meter will hold at OVER RANGE in fields as high as 100 times the maximum reading.

AVERAGING PERIODS

Display updates every 3 seconds. At low background levels, the update is the average for the past 30-second time period. The timed period for the average decreases as the radiation level increases.

DISPLAY

Graphic Display with Backlight

COUNT LIGHT

Red LED flashes with each radiation event

AUDIO INDICATOR

Internally mounted beeper (can be switched off for silent operation)

OUTPUTS

USB for use with Free Observer USB Software for PCs

POWER REQUIREMENTS

Two AA alkaline batteries (included)
