RAD7 Electronic Radon Monitor/Sniffer

Highlights

It is both a sniffer and a continuous monitor.
Measures both radon and thoron. Shows both on the spectrum printout.
Fastest response and recovery times of any electronic monitor/sniffer on the market.
Easiest to use. Microcomputer directs you, step by step, so you can do what you want to do.
Programmed set-ups for often-used tests.
All-in-one complete, compact, portable unit in handsome rugged carrying case.
Weighs just 11 pounds.
Measures EPA action level of 4 pCi/l in just one hour.
Recovers from radon highs in minutes - not hours.
Gives you faster, more sensitive, more reliable readings.
Displays and prints continuous updating of radon level from start of test.
Displays, prints and downloads data in your choice of units
Audible radon and thoron counts. Lets you hear the hot spots.
Tamper-proof computer command secures your RAD7. Assures proper testing.
Spectrum readout verifies correct operation of instrument in field.
Hewlett-Packard printer included in price. Infra-red data link for on-the-spot printouts.
Rechargeable battery.
Built-in air pump.
RS-232 port.

RAD7 is everything you ever wanted in an electronic radon monitor.


FEATURE	Specification
MULTI-MODES	Continuous Radon Gas Monitor Long-term/Short-term screener Sniffer, with small tube "snout", to search for radon and thoron entry points.
MULTI-MEASUREMENTS	Measures radon in air, soil, and water (with RAD H₂O accessory)
SENSITIVITY	Monitor: 0.4 counts/min/pCi/l Sniffer: 0.2 counts/min/pCi/l
RANGE	0.1- ----> 20,000 pCi/l
MEMORY	1,000 previous radon concentrations, and associated data. Can be read out on LCD, down loaded and/or printed out. Also shows high, low, average and standard deviation of readings.
PRINCIPLE OF OPERATION	Electrostatic collection of alpha-emitters with spectral analysis.
BUILT-IN-AIR PUMP	Nominal 1 liter/minute flow rate. Inlet air filter Inlet and outlet air connectors.
SPECTRUM READOUT*	Pulse height spectrum of alpha distribution verifies radon/thoron, and also shows the RAD7 is operating properly. Accurate determination of the alpha particle energies creates a radon signature that allows discrimination of radon and thoron's alpha particles from those of other isotopes.
FAST LOW-LEVEL READINGS*	In Continuous Monitor mode, RAD7 measures the EPA action level of 4 pCi/l in just 1 hour (60 minutes), with standard deviation of 10%. Since the RAD7 has virtually no background, it is much more sensitive than other electronic detectors, easily measuring down to 0.1 pCi/l
RECOVERY IN MINUTES*	Recovers from high radon exposure with a 3.05 minute half-life: to less than 10% of peak value in 12 minutes; to less than 1% of peak value in 30 minutes. Drops from 20,000 to 1 pCi/l in 8 hours.
TAMPER PROOF*	A "Test Lock" command is programmed into the machine to secure your RAD7 against all kinds of intentional or unintentional tampering.
AUTO MODE*	This setting starts a test run in Sniff mode, then switches to Normal mode after the first 3 hours. No more waiting for equilibrium. Gives quick response, followed by statistical precision.
CONTINUOUS UPDATING*	Gives continuous update of radon levels so you can see the trend at all times, not just at pre-set intervals.
COMPUTER LCD DISPLAY	2 line X 16 character, alpha-numeric. easy to read
AUDIBLE RADON COUNT	Indicates presence and intensity of radon and thoron. May be turned on or off.
POWER	AC/Battery powered - 5 AH 6V batteries. Automatic charge when plugged in. Continuous battery operation: 24 hours in Sniffer mode; 72 hours in Monitor mode.
PRINTER	Hewlett-Packard Model HP 82240A
RS-232 PORT	Computer/modem hookup
OPERATING RANGE	Temperature: 40° - 105° F.(5° - 40° C.) Humidity: 0 - 100%, non-condensing.
WEIGHT/SIZE	11 pounds complete - 9.5" X 7.5" X 10.5"
CASE MATERIAL	High density polyethylene.
