KM 2000 CnHm EM | Hydrocarbon Analyser

Product catalog summary

Introduction
The ADOS KM 2000 CnHm is a hydrocarbon analyzer designed for measuring combustible gaseous CnHm compounds, excluding chlorinated and sulfur-sublimed hydrocarbons. It is used in industrial process supervision and room air monitoring to ensure compliance with clean-air regulations.

Fields of Application

Supervision of industrial processes, measuring hydrocarbon emissions according to German clean-air regulations.
Monitoring solvent saturation and concentration.
Room air monitoring to issue warnings at low concentrations of poisonous gases.

Measurement Principle and Functioning
The analyzer operates on the principle of heat reaction, using a catalytic converter to measure the heat of combustion. The temperature difference between the reference and measuring points indicates the concentration of combustible substances.

Gas Measurement System

Gas is drawn through a heated feed pipe to a reaction chamber.
Components include a compensating filter, flow regulator, and flow-through meter.
The gas is burned in a catalytic converter, and the temperature difference is analyzed by a microcontroller.

Equipment Construction

19" rack units include a reaction chamber, gas suction system, and microcontroller-aided evaluation unit.
Optional features include heated sampling probes and automatic calibration systems.

Technical Specifications

Measurement ranges: 0–50 mg/m³ TOC to 0–1600 mg/m³ TOC.
Minimum detection limit: 1 mg/m³ TOC.
Output signals: 0–(4)–20 mA current interface, RS 232.
Response time: < 200 sec.
Accuracy: < 2% full-scale error.
Permissible ambient temperature: +5 °C to +40 °C.
Sampled gas flow: 125 l/h (±10 l/h).
Maintenance interval: 4 weeks with auto-calibration, 1 week without.
Mains supply: 230 V / 50 Hz; 115 V / 60 Hz; 600 VA.
Dimensions: 600 x 478 x 500 mm; Weight: approx. 43 kg.

Cross Sensitivity

SO₂: -10% deviation at 200 mg/m³.
NO₂: -2.5% deviation at 30 mg/m³.
CO: +108% deviation at 300 mg/m³.
NO: +7% deviation at 300 mg/m³.

Certification
The KM 2000 CnHm has TÜV approval according to clean-air regulations ("TA-Luft").
