New! PE5 Electrode
Long life: slow to dry, easily rehydrated
Only 13 cm x 7.25 cm dia., 0.75 kg
Flat response from DC to 10 000 Hz
Low noise, low offset, low drift
Porous ceramic contact surface and conductive slurry prevent
polarization
Heavy-duty PVC and ABS construction protects against foul
weather and temperature variations when buried in the earth
New! TEM-AL MulTEM Loop
Only 3.2 kg; 55 cm x 53 cm x 6 cm
Effective area: 100 m2
Built-in bubble level
Bandwidth: 40 kHz, critically damped
Low noise (4 x 10
7
nT/ Hz at 1 kHz)
Anti-saturation circuitry
Operating temperature: 40 to 50 °C
Independent tests proved that the performance of the new Phoenix
TEM-AL loop equals or surpasses the performance of previousgeneration loops (Phoenix or Geonics). The late-time response has
been improved without compromising early-time response. The
dramatic reduction in size and weight makes it easy to deploy multiple
loops for up to three simultaneous EM measurements at the V8
receiver.
