The MLT7006, MLT0015 and some 3rd party transducers (ie from UGO Basile) DO NOT operate with ML118 Quad Bridge Amp or ML119 Octal Bridge Amp (the ML118 and ML119 are now discontinued).
The MLT7006 and MLT0015 isotonic transducers require the ML221 Bridge Amp, ML224 Quad Bridge Amps or the ML228 Octal Bridge Amp.
