荷兰Metris成立于1994年.
Metris LABORAS系统是一套利用动作感应器及震动侦测原理，无关乎实验环境的采光问题，可以在全黑的环境下运作，且不需要要求动物的颜色，即可自动侦测几项常见的动物行为，包括：Locomotion、Resting、Rearing、Climbing、 Crooming、Drinking 及Eating,並积极研发扩展其他Stereotyped Behaviors等。
LABORAS的系统，除了可以提供动物在饲养笼中，自由活动的轨跡、行进的路径及距离、行进的速度、平均、极大值， 以及偏好位置的分佈。

Metris was originally founded in 1994 and registered as Metris System Engineering V.O.F. In May 1999, new shareholders joined the company and the legal personality of the company was changed, resulting in it's current name: Metris B.V. The development activities were intensified and several innovative products in the field of automated animal behavior recording and analysis were developed since then.

Today Metris is generally seen as one of the trendsetters and marketleaders in the field of animal behaviour research equipment.
Metris is already for several years the only provider of independently validated research equipment that determines the behavior of small laboratory animals non-invasively and without any human observation.

Our on-going innovations and the use of state of the art technologies and materials garantuee that our products provide unique functionality and high reliability. By working closely together with our customers the products also have a customer driven design and have significantly increased the efficiency of the research work done by our customers. Our products LABORAS and SONOTRACK are the direct result of this approach. Both systems resulted in increased efficiency compared to existing systems or methods.

A full understanding of all customer requirements and the design of systems that lead to increased efficiency and productivity will remain the basis of our approach for the years to come.
