Which model is suitable for your application?
If dose rates above 10 mSv/h are not expected, the 6150AD2/E or
AD6/E is preferable because the more sensitive detector is better
suited for low levels. Otherwise, the 6150AD1/E or AD5/E is the
better choice (or, to cover a very large area, consider the
sensitive AD2/E or AD6/E with a 6150AD-15/E gamma probe for high
dose rates).
-
Protection against accidental switch-off (button must be pressed
twice in the basic state).
-
Non-volatile storage of the dose of the built-in counter.
-
Dose warning.
-
Freely programmable warning thresholds for dose and dose rate.
-
Better resolution (more decimal places) when displaying dose,
warning thresholds, etc.
-
Displays the relative standard deviation of the mean dose rate.
-
Detection of the scintillator probe 6150AD-b/E.
All models mentioned in the table above are designed for readings of
H*(10) and calibratable. The predecessor models without the suffix
“/E” on the type designation are designed for the old reading Hx and
are therefore only “re-calibratable”. For new purchases, we only
recommend the models listed in the table above for the German
market.
According to the requirements of the Physikalisch-Technische
Bundesanstalt (PTB), the reading must be readable on the display
device for calibratable devices. To meet this requirement, “/E”
models may only be compatible with “/E” probes. This must be taken
into account when purchasing new products if the old 6150ADs or old
probes (without the addition of “/E” are still in use). The
following table provides an overview of the compatibility (yes or
no) of the basic device 6150AD and probes

H*(10) probes (without “/E”):
6150AD-15/E, 6150AD-18/E, 6150AD-t/E, 6150AD-b/E |
no |
yes |
| All pulse rate probes (display s-1, z.B. 6150AD-17, 6150AD-k) |
yes |
yes |
The pulse rate probes (e.g. 6150AD-17, 6150AD-k) are not affected by
the new readings and are therefore compatible with all 6150AD
display devices.
We also have models of the 6150AD and Sievert probes that use the
same detector as the /E models and therefore measure H*(10) as well
as the /E models yet are compatible with the old devices for Hx .
These models then have the suffix “/H” in the type designation.
These /H models are mainly intended for use abroad because we do not
want to burden our customers there with losing the compatibility
with old devices when changing to the new measurement parameter. For
the German market, however, we had no choice but to prevent
compatibility with old devices with the new measurement parameters.
