STM-2XM
2-Channel Rate/Thickness Monitor

Product configurator
Gemini™ MxG5xx
STM-2XM is a two channel rate/thickness monitor that combines high accuracy with flexible programming and easy operation at an affordable price.
STM-2XM is equipped with five operation modes to accommodate processes from simple to complex. For example, use simple mode to monitor just one single sensor for the simplest process or use alloy mode for codeposition monitoring. Independent mode allows STM-2XM to function as two completely separate monitors.
Two sensor inputs allow for the use of two single or one dual quartz crystal sensor. 10 measurements are taken per second while achieving a resolution of 0.037 Å per measurement (density of 1).
Feature Packed
STM-2XM has eight programmable digital inputs, eight programmable digital outputs, and four analog outputs allowing for a level of integration usually reserved for more expensive instruments.
Programmable features include shutter delay, time/power monitoring, and rate sampling. Use all of these features to achieve the most accurate readings and the longest crystal life.
Operate and monitor STM-2XM either through the simple front panel interface or through the included LabVIEW® software. This simple software is fully functional and easy to use.
Easy to Use
STM-2XM features a high contrast LCD display and intuitive menu system. On-screen hints can be found throughout the menus for simple, guided programming and operation. The easy-to-read LCD can display in accumulated mass or thickness.
