I use the thermometer in clinical use. Is made possible by the one-changers so that hygienic working conditions is fully possible. What can I say. The temp. Display are correct. Have comparative measurements with other thermometers in various parts of the body carried out (note the possible fluctuations especially in axilarer / sublingual measurement). However, the time savings makes all the difference. Whether I now 5 seconds when patients need or measurement type for several minutes making 30 or more patients already NEN big difference. And just in night service, the patients are very grateful for the quick and easy measurement without much effort. And almost all are very glad to get inserted rectally not always NEN thermometer. Conclusion: time saving, patient happy ....
