Description

If you need to separately count alpha & beta concurrently and log the results, the Model 2360 will be the right tool. Model 2360 is an optimized Alpha Beta Ratemeter/Scaler/Data Logger that offers traditional analog readout supplemented with a digital LCD for the scaler function. Up to 550 data points consisting of sample number, date/time stamp, both alpha & beta sample measurements and 10 character location identifier. The location identifier can be input via an optional external device through the RS-232 serial port. A front panel mounted three way switch facilitates selecting alpha only, beta only or alpha plus beta. Other controls include a rotary switch for selecting any of 4 decades, battery test and instrument shut off, a switch for viewing the high voltage or resetting the counts, an audio volume adjustment knob, a scaler count time selector rotary switch and finally a handle mounted push button for logging and starting scaler count cycles.

Specifications

INDICATED USE: Alpha, beta discrimination, and data logging
SUGGESTED DETECTOR: Dual phosphor scintillation and gas proportional detectors
DATA LOGGER: Capable of storing up to 550 individual data points with the following identifiers for each point: (All data is stored in non-volatile memory allowing batteries to be removed without loss of data)
Alpha and beta sample counts
Sample number
Date/time stamp
Scaler count time
10 character location identifier
LOGGING PUSHBUTTON: Located in handle; used to activate scaler and/or log a count
LOGGING FUNCTION CONTROL: Internal selection that enables the pushbutton to log a ratemeter reading, initiate a scaler count and log the resulting reading, log both the scaler and ratemeter reading, or disable the logging function.
LOCATION CODE: A 10 character alphanumeric identifier. (can be set by ASCII terminal or PC)
CALIBRATION DUE DATE: An internal date that disables the instrument if the required calibration interval has been missed.
HEADER INFORMATION: Six lines of user defined memory at the beginning of the stack for storing user name, survey name, serial numbers, etc. (information is dumped with logged data)
RS-232 PORT: Located on the can, this allows the instrument to be connected to a PC for dumping of data, and setup of parameters.
AUDIO: Built in unimorph speaker with volume control (greater than 60 dB at 2 feet, full volume). Selectable dual or individual clickper- event for alpha and beta counts and divisions of 1, 10, 100, or 1000 events per click (beta counts only)
METER DIAL: 0 – 500 cpm, 0 – 2 kV, BAT OK, OL (overload)
MULTIPLIERS: X1, X10, X100, X1000
LINEARITY: Reading within 10% of true value
SCALER: 6 digit LCD display with 0.25”(0.64 cm) digits, overflow arrow, colons to indicate when a count is in process, and backlight
COUNT TIME: Switch selectable times of 0.1, 0.5, 1, 2, 5, 10, 60 minutes, or PC to allow for a specific count time to be set from a PC.
SELECTOR SWITCH: Toggle switch to select alpha+beta or “alpha”, only, or “beta” only
ALARM: The Model 2360 has alarm capabilities on both the scaler and ratemeter. Both circuits allow for independent alarm settings of the alpha channel, beta channel, and the alpha/beta channel. The scaler alarm setpoints can be set at any point from 0 – 999999 counts. The ratemeter alarms can be set at any point from 0 – 999999 cpm. Alarm points can be set via the keypad, or PC.
RESET/READ HV: A two position momentary action switch to allow for the meter to be reset or a reading of the HV setting
HIGH VOLTAGE: Adjustable from 200 – 2000 volts (can be read on meter)
OVERLOAD: Senses detector saturation. Indicated by red lamp on meter and meter deflecting to full scale (internally adjustable)
RESPONSE: Will vary according to number of counts. Typically 2 – 11 seconds from 10% – 90% of final reading.
BATTERY LIFE: Typically 150 hours with alkaline batteries (battery condition can be checked on meter)
TEMPERATURE RANGE: -4° F to 122° F (-20° C to 50° C) May be certified for operation from -40° F to 150° F (-40° C to 65° C)
SIZE: 6.5” H x 3.5” W x 8.5” L (16.5 x 8.9 x 21.6 cm)
WEIGHT: 3.5 lbs (1.6 kg), including batteries
