The A2702 is a compact
transistorized electronic
galvano meter using a battery.
With sensitivity of 10§Å/div,
this instrument is highly
suited to field measurements
and as an indicator for
complex measuring instruments

The A2708 Galvanometer
is a compact pointer type
with a short period (1.9
seconds). It employs a shock-and
vibration-proof hair spring
suspension system. This
unit is also suitable for
classroom application
¡á EXCELLENT
SHOCK-AND VIBRATION-PROOF
DESIGN
The

minimizes the effect of
external vibration and impact.
¡á QUICK RESPONSE
The
period is as short as 1.9
seconds, permitting fast
measurements.
