UTL-3 Temperature Datalogger

UTL-3 Scientific Datalogger es un poderoso registrador de datos en miniatura para la medición y el registro profesional de temperatura. Es la mejor opción para medir las temperaturas de permafrost, hielo, aire, agua y suelo en ambientes desafiantes.

Fue desarrollado con el conocimiento experto de GEOTEST y el Instituto Suizo de Nieve y Avalanchas (SLF) y es uno de los registradores de datos de temperatura más fiables y sólidos en el mercado. El registrador de datos UTL-3 y los modelos anteriores UTL-1 y UTL-2,  han sido empleados miles de veces para mediciones en ambientes fríos tales como hielo, glaciares, glaciares de roca y  suelos de permafrost para mediciones de temperatura de agua y aire.
