AlarmTritium alarms, gamma alarms, low air flow alarms will all be shown by red LED light and by an audible device.
DrierNote that the silica gel drier is not part of the standard equipment, but can be supplied as an extra.
CommunicationCan be configured to RS232(Short distance) or RS485(Long distance).
DisplayGraphic touchscreen LCD display. Unit displays the values(tritium and Gamma) both in numerical format and graphical trend.
Analog output0-5 V Linear or logarithmic voltage output.
Purge/DecontaminationAll 4 Chambers can be heated up by a cartridge heater controlled by unit
Background cancellationLess than 10% of the reading change in 20 mR/hr field
Zero stability±1µCi/m³ immediately after unit is powered on
Ion trapBuilt into each ion chamber
Sensitivity1µCi/m³ ( 0.05 DAC)
Radon compensationIncluded in the software
Noble gas cancellationPorts for air inlet/outlet of measuring chambers and compensation chambers are accessible on surface plate so silica gel drier can be placed between the chambers to compensate for presence of noble gas.
Flow rate1.0 L/m
Dust filterBuilt into the unit.
Detector4 matched chambers - Two for measuring, two for compensation
Measuring chamber effective volume500 cc (2 measuring chambers of 250cc each)
Tritium DiscriminationInstrument can discriminate in a field of HTO and elemental H3 using the silica gel drier.
Gamma measurementGamma is measured directly by the unit. Gamma measuring range is from 0.1mR/h to 10R/h
Data loggingThe tritium and gamma values are logged every minute with current time and date stamp
Size and weight8"(L)x5"(H)x5"(W), 7 lbs.

Compensation for Gamma background is crucial in tritium measurement, since a gamma field of 1mR/Hr will generate 500 times the ionization generated in 1µCi/m³ of tritium. Tyne designed the four, 250 cc ion –chambers in a cruciform with each chamber connected to an ultra sensitive electrometer amplifier and filter. All signals pass through the ADC converter, and the micro-processor calculates and displays the tritium value. To cover high ranges of tritium a separate small ion chamber is used. Measurements such as flow from the solid-state flowmeter and chamber temperature are also monitored by the micro-processor.

Instrument output includes analog (0-5V, 4-20mA); relay alarm contact (30VDC, 1A) for operation of external equipment; and communication (RS232/RS485) to enable downloading or recording of information onto a computer. The TFT full color LCD display mounted on the surface plate clearly displays instrument readings in both digital and graphic format to show real time measurements and trends.

The well balanced, easy-to-carry instrument can be placed on its end for easy visibility of the touch screen monitors to operators working away from the instrument.

Batteries installed in the handle are easily replaced.

A powerful long-life pump can be used to draw air through a 10 meter tube. This allows the instrument to be used to measure the inside of rooms without the need to enter the room.
