DESCRIPTION: Technical Associates PTG-7RN Radon Monitor is a
sensitive, rugged, portable instrument for detection and
measurement of airborne radon. Its' subtractive balanced chamber
electro - meter circuit decreases background effects to negligible
levels and its deionized and filtered intake reduces to negligible
levels spurious effects from smoke, dust and existing ionization in
the air. Inlet and outlet hoses allow monitoring interiors of fume
hoods, exhaust stacks, etc. The PTG-7RN will measure airborne
radon as free Radon gas (with or without Radon Daughters at users
option) as low as 1 Bq/m3.
All instruments are calibrated at the factory. Calibration check may
be performed in the field with a microCurie level beta-gamma
source. Chambers may be switched to additive operation to check
linearity of response on a gamma calibration range. User friendly
calibration controls are provided.
SPECIFICATIONS:
•Ranges: Large, easy to read digital LED readout. Two ranges cover six decades: 2.0 to 2 x 106 picoCurie/liter
•Background: Essentially eliminated by subtractive balanced chambers.
•Smoke, Dust and Ion Elimination: Filter and deionizer reduce effects to negligible level.
•Circuit: Electrometer circuit amplifies net difference between a two liter radon internal chamber and a sealed
background chamber of similar configuration.
•Alarms: Low Air Flow Alarm High Level Alarm: Red Lamp and Audio Alarm.
•Controls: Front Panel Off-On range switch calibrate switch. Alarm set button, alarm reset button.
•Calibration: Can calibrate internally with radon gas, or on a calibration course, or (at a single point) with
optional beta source.
•Printer: Plug is furnished for optional external serial printer.
•Computer Port: RS-232 serial port is built in (fully addressable).
•Portability: PTG-7RN is provided with carrying handle and optionally with loops for shoulder sling.
•Case: Deep drawn aluminum case, with handle and gasketed lid, easily clean-able anodized finish.
•Dimensions
Instrument Case (Including handle): 9''W x 16''L x 14-1/2'' Tall.
Front Panel: 15-1/4'' Long x 8-1/4'' Wide.
