概要

The EMIA-V2 series measures carbon and sulfur extracted during combustion in a programmable High Frequency furnace without conversion. Combustion control is achieved through the use of the high-frequency induction furnace method. Appropriate heat-control in accordance with the analysis objective enables high-precision analysis for all types of samples. A variety of models allow you to select the furnace system that is best suited to your target samples and application.

• EMIA-920V2 C/S analyzer: High performance analyzers with outstanding accuracy of less than 0.3ppm
• EMIA-320V C/S analyzer: Standard performance analyzers for wide range of applications.

特征

• "Auto cleaner" mechanism reduced maintenance works
  (Standard for 920V, Option for 320V2)
• The Dust filter heating mechanism provides stable analysis with extremely low gas absorption
  (920V2 only)
• Real-time simultaneous detection of CO/CO₂/SO₂ without an oxidizing (CO→CO₂) or SO₃ trapping reagents.
• Wide variety of self diagnostics
• Programmed temperature curve for optimizing combustion.
• Choose from standard or wide range models to suit your application requirements.
