Meisi An 90109020 Wall mounted Multi channel Controller from the United States

1、 Product Introduction

MSA 9010 and 9020 are imported instruments with complete functions and reliable performance. By configuring various types of gas detectors, reliable gas monitoring and alarm can be provided, providing safety services for various industrial fields.

There are two models of instruments: 9010 and 9020 controllers. Among them, 9010 is a single channel instrument that can be equipped with one gas detector, and 9020 is a dual channel instrument that is independent of each other and can be equipped with two identical or different gas detectors at the same time.

There are three specifications of racks that can be used for instruments: a 19 'rack can accommodate 10 control units, a 19/2' rack can accommodate 5 control units, and a 19/5 'rack can accommodate 2 control units.

There are three types of wall mounted structures for instruments, namely wall mounted one channel (9010 per unit), two channel (9020 per unit), and four channel instruments (902 per unit).

In addition, the instrument can be equipped with various domestically produced wall mounted boxes.
