The Edan 12.01.31527-01 is a clinical-grade external tocodynamometer transducer engineered specifically for uterine contraction tracking. Crafted to service legacy screening setups, this replacement probe measures the relative frequency, duration, and strength of uterine activity from the maternal abdominal wall during antepartum and non-stress evaluations. The probe features a completely flat, waterproof faceplate assembly that optimizes physical comfort while protecting fragile interior piezoresistive crystal sensors from acoustic coupling gels and cleanings. It relies on a specialized pin terminal setup that ensures error-free connection stability when paired with classic monitoring consoles lacking internal DECG integration pathways.
