Registrador USB de 4 Canales y 12-bit T/HR/2xExt. Permite registros de temperatura/humedad
relativa con sensores internos de alta precisión, interfaz USB y resolución de 12-bit.  2 Canales
externos versátiles que admiten la misma gama de sensores externos que la familia H8.
El U12 puede inciar las medidas por medio de un pulsador en el panel frontal.
