SE International รหัส Alert Ranger เครื่องวัดรังสีพร้อมเซ็นเซอร์แสดงผลดิจิตอล,Digital radiation meter with internal sensor

• 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!
• Bluetooth for use with the Free Observer BLE App for Android.
• Optional wipe test plate for swipes.

• 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
  • µSv/hr - .01 to 1000
  • CPM - 0 to 350,000
  • 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)

•  Data Logging Capacity

     5,452 data points, which at 1 minute intervals as an example, equates to 3.7 days

•  Outputs

    USB for use with Free Observer USB Software for PCs

•  Power Requirements

    Two AA alkaline batteries (included)

•  Size

    140 X 68 X 33 mm (5.5 X 2.7 X 1.3 in.)

•  Includes

    Carrying Case, Xtreme Boot, Stand, Mini-USB Cable, Observer USB Software Download , Certificate of Conformance

•  Options

Wipe Test Plate, Swipes, NIST Calibration
