First and foremost, our Survey Meter offers maximum performance in a lightweight, rugged nuclear radiation detector for surveying at the facility or in the field. Furthermore, Though designed with industrial environments in mind, it still has all of the features you’ve come to love in the lab. Moreover, it has small, handheld, digital survey meter that offers excellent sensitivity to low levels of alpha, beta, gamma, and x-rays.

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 1.77″ (45mm)
• 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 Settings – mR/hr .001 – 100 and CPM 1 – 350,000. 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.
• Averaging Periods – This radiation detector 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.
• Anti Saturation – Meter will hold at OVER RANGE in fields as high as 100 times the maximum reading.
• Display – Graphic LCD 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
• Power Requirement – USB Power or Two (2) AA alkaline batteries (included)
• Humidity – 10% to 70% Non-Condensing.
•Temperature Range – -10° to +50°C (14° to 122°F)
• Size – 140 X 68 X 33 mm (5.5 X 2.7 X 1.3 inch.)
• Weight – 291g
• Limited Warranty – 1 year limited warranty
