# Introduction

This manual is a user guide for the Boomerang 3 system, offered by ICU Scandinavia AB.

The Boomerang 3 system is an automatic system for logging and monitoring physical parameters such as temperature, relative humidity, and pressure.

It makes monitoring and quality assurance of your laboratory simple, precise, and efficient.

The system automatically collects information about parameters, for example, in refrigerators, freezers, incubators, and heating cabinets.

It triggers alarms if pre-set thresholds are exceeded. The alarm messages are delivered to designated contacts using defined methods such as e-mail, SMS, and voicemail.

It offers extended management including:

* user accounts with six levels of rights that enable a security system definition to reduce human-related threats,
* multilevel administration groups to reflect the company or department structure,
* infrastructure to define the hardware elements that deliver the measurements to the system,
* alarm definitions, with alarm ranges defining the conditions and alarm groups defining the distribution.

The Boomerang 3 was developed based on more than 20 years of experience in the field of automatic quality assurance.

ICU Scandinavia AB reserves the right to modify or update this document at any time without notice.
