Unusually quick response time: T₉₀ ≤ 3 sec : LFE´s unique principle modifies the "classical" method by spatially and electrically decoupling the heated element from the temperature sensing element.

• CONTHOS 3 - TCD | thermal conductivity analyser - steel- and petrochemical industries - highly corrosion- and temperature resistant TCD detector
  
  
• CONTHOS 3 - TCD Ex p | ATEX therrmal conductivity gas analyser - ATEX Ex p version for zones 1 and 2 - steel- and petrochemical industries - highly corrosion- and temperature resistant TCD detector

LFEs Paramagnetic Oxygen Gas Analyser
up to 3 measuring ranges and quick response time T₉₀: typically 3 sec.

• CONTHOS 3 - PMD | paramagnetic Oxygen gas analyser - temperature controlled for increased accuracy - intuitive user-interface based on NAMUR recommendations - automatic self-diagnosis

Extraordinarily stable measuring characteristics
LFE develops and manufactures key components in order to attain exceptionally stable measuring characteristics.

• TOC-810 | Online-TOC-Analysator - continuous TOC analysis with high-temperature oxidation method

• pControl 2F - Backpressure Controller for process gas analyzers -
  the LFE backpressure controller provides for an extremely constant pressure over an extremely wide range of gas flow - the return of the analyzed gases back into the process is a further benefit
  
  
  
  
• USR-F | Sample Filter System with Ultrasonic Irradiation
  - using a cross-flow filter element for online process water analysers - the filter element is irradiated at adjustable, regular intervals by ultrasonic energy (cavitation bubbles)
  
  
  
• USR-S | Ultrasound Cleaning System for process liquid analytical sensors
  - applies to process liquid analytical sensors such as pH electrodes or conductivity sensors - the sensors mounted in a cross flow vessel are irradiated at adjustable, regular intervals by ultrasonic energy (cavitation bubbles)
  
  
  
• Series 54 Peristaltic Pump
  - sample transport - condensate transport - sample dilution - sample metering - long service life through high mechanical and chemical resistance
  

• Analysis Cells for Process Photometers
  - flow cells for process photometer - continuous operating temperature up to 160°C - suitable for UV, VIS and IR process photometry (i.e. LFEs on-line TOC-analyzers)
  
  

• Specific Gravity Sensor
  - for the continuous, on-line analysis of a gas stream - utilizes an acoustical principle - the high selectivity to the density is the result of proper chamber geometry, dimensioning and operational parameters
