XX Migration of the Labguard system to the JRI-MySirius temperature monitoring solution: The success of the Orléans Regional Hospitality Centre

“Nous avons rapidement trouver nos marques dans l’application JRI-MySirius car il y a plusieurs similitudes avec le logiciel Labguard. “We quickly found our feet in the JRI-MySirius application because it shares several similarities with the Labguard software. It’s intuitive to use, and more of our technicians are connecting to it. From a hardware perspective, we also appreciate that the Nano SPY LINK’s light strip warns of an ongoing alarm. This allows us to be even more responsive in our support.”
