Your Application Advantages

Q-tag CLm

Clear and easy to read
Internationally recognised symbols show the alarm state clearly. The devices work completely independently; all information shown on the screen is comprehensible and readable, and is saved in such a manner that it cannot be manipulated. Simple and extremely user-friendly!

Swiss quality in a compact format!
Each transport is unique and unpredictable due to the constantly changing ambient temperature. With their easy handling and the low logistical costs, our electronic indicators are the ideal solution for efficiently monitoring all types of transport. Berlinger Indicators are highly accurate electronic temperature monitors. Calibration traceable to ILAC recognised international standard (e.g. SAS, NIST) upon request. As precise as a Swiss watch!

Individual alarm programming
5 different alarm temperature und time limits can be modified individually to the product and customer requirements. Take control!
