MGas NH3 5.1

FUNCTION

The instrument for measuring the following Gas- Concentrations

• Ammonia %NH3

Customizable Gas components are possible.

Additional measurement:
– Temperature Based on state-of-the-art Tunable Diode Laser Spectrometry (TDLS) with high accuracy, good long-time stability, and excellent repeatability, this equipment is qualified to measure furnace atmospheres online.

Eight analogous outputs, eight digital inputs/outputs, and an optional serial interface are possible. All Analog and Digital inputs/outputs can be configured manually e.g. as Alarm, starting calibration, or switching off-pump. An optional data logging function with USB data transfer and internal memory with 16MB is available. The logging function can work in manual or timer mode. With the delivered Software “MGas Viewer” you can visual, print, export, and administrate your stored data. The equipment is adjustable by a high- quality foil keyboard with self explainable menu structure in German and English language. Automatic calibration for zero-point and span for all gas components is possible. Additional it is possible to configure several protection functions, e.g. low process temperature, in order to increase the lifetime of the device.
