The EC6 is an
accurate, easy-to-use strain gauge and photo
plethysmograph for use in a wide variety of
measurement applications. This unit replaces the
EC4 Plethysmograph which has been popular for
many years as the lowest cost strain gauge
plethysmograph with in-situ electrical
calibration.
The EC6 will handle mercury strain gauges from 2
to 50 cm for all limb and digit volume
measurements. In addition, an infrared photo
transducer may be used as a sensitive pulse
detector for blood pressure and venous reflux
tests.
The analog
output may be AC or DC coupled for
arterial and venous tests. Seven
sensitivity ranges span 2% (8% full
scale) to 0.02% volume change per
division on the meter. The analog output
is adjustable from ±20 mV to ±2 Volts
full scale so that most chart recorders
can be used with the EC6 including the
AD Instruments PowerLab.
Calibration and zeroing of the output is
accomplished at the push of a button or by a
remote switch or signal. Auto balance is also
available, which will reset the signal whenever
it goes beyond the scale of the meter on the
instrument.
The built-in RS232 data output is optically
coupled for safe use with an external computer.
The EC6 is fully compatible with our NIVP3
software so that automatic arterial inflow or
maximum venous outflow (MVO) measurements can be
made.
