The Model 3276 is a versatile instrument that can be used for multiple radiation detection or measurement purposes. It is used with either an internal or an external radiation detector to detect alpha, beta, or gamma radiation in applications such as frisking or area monitoring.
It features a large, backlit, easy-to-read LCD screen and audible alarms and is controlled using a simple four-button interface. The unit body is made of lightweight, rugged aluminum. It is not intended for outdoor use and should be protected from splashing water. The attached metal handle facilitates transportation between sites. The instrument can be wall-mounted for area monitoring applications or mounted to a stand for desktop applications such as frisking (see options).
The Model 3276 can measure radiation in count rate, exposure rate, exposure rate/dose, activity rate, integrated exposure/dose, time-averaged rates, and scaler counts. When used as a frisker, three modes of operation are available – RATE, MAX, and COUNT – which can be selected by pressing the MODE button. When used as an area monitor, only RATE mode is available by default. Measurements can be collected in two sets of units (primary and secondary) for RATE and MAX modes in cps, cpm, Bq, dpm, R/hr, or Sv/h units. The user can switch between the two sets of units by pressing the UNITS button. When used as a frisker with a scintillation detector, a sigma audio mode can be enabled that allows the user to find small increases above the background radiation level.
Instrument setup can be done either through the front-panel controls or via the Lumic Calibration Kit (PN: 4498-1018). Power is supplied by either four alkaline “AA” batteries or a 9 Vdc wall mount transformer. The Model 3276 is shipped ready to use with batteries, a wall transformer, and a calibration certificate.
* 3276/1 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 Energy Response Curve.
The Model 3276 can be configured to be used with Model 375 software. Click here to view the hardware requirements for each software.
Note: Because the Model 375 software uses a fixed unit display, the preferred unit of measurement for the display must be specified when ordering (ex: mR/hr, µSv/h). The Model 3276 minimum and maximum display parameters must also be set to preclude units other than those specified for the software.
Desktop Stand
Wall Mount with Detector Cradle with Switch for Model 44-9(detector not included)
Includes a mounting bracket for the Model 3276 and a detector cradle with a switch for the Model 44-9 detector. (Model 44-9 detector not included.) The audio is silenced while the detector is in the cradle and is enabled when the detector is lifted from the cradle.
Dimensions (H x W): 15.5 x 26.1 cm (6.1 x 14.2 in.)
Includes a mounting bracket for the Model 3276 and a detector cradle for the Model 44-9 detector. (Model 44-9 detector not included.) Does not include switch to control audio (see above).
Strobe & Horn
12 V Strobe & Horn assembly with relay
Remote Display
Includes Model 272D remote display, RS-232 option, and cable.
Note: Because the Model 272D has a fixed unit display, the preferred unit of measurement for the display must be specified when ordering (ex: mR/hr, µSv/h). The Model 3276 minimum and maximum display parameters must also be set to preclude units other than those specified for the Model 272D.
In order to use the latest Lumic Calibration Software*, you may need to update the firmware on your instrument. (All new instruments will be compatible with the latest software version.) Use the table below to determine the firmware requirement for your instrument.
