DESCRIPTION: Technical Associates PTG-7 Tritium Monitor is
a sensitive, rugged, portable instrument for detection and
measurement of airborne tritium. 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. The PTG-7L is the
bench-top version of the PTG-7. It is line operated and
it maybe left on permanently without fear of "running
out of battery". Inlet and outlet hoses allow
monitoring interiors of fume hoods, exhaust stacks, etc.
The PTG-7 will measure airborne tritium as free hydrogen
or as volatile chemicals in concentrations as low as 1 x
10^{-6} uCi/cc of air. (37 KBq/m^{3})

All instruments are calibrated at the factory. Calibration
check may be performed in the field with a microCurie level
beta source. Chambers may be switched to additive operation
to check linearity of response on a gamma calibration range.
User friendly calibration controls are provided.

TRITIUM MONITOR

Model # PTG-7 Portable

Model # PTG-7 Line Operated

SPECIFICATIONS:

Ranges: Large, easy to read digital LED readout. Two ranges
cover six decades: 1 x 10^{-6}
to 1.0 uc/ml (37 KBq/ml to 3.7 x 10^{10}
Bq/ml.)

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 tritium 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 tritium 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).
