QAL 181 CEMS Certified particulate monitor

Product catalog summary

Overview: The QAL 181 is a QAL 1 approved particulate measurement system utilizing forward-scatter technology with a minimum detection limit of less than 0.05 mg/m³. It features ProScatter™ technology, which enhances measurement accuracy by reducing cross-sensitivity to particle type and size.

Key Features:

Robust design suitable for high-temperature conditions up to 500°C and hazardous zones.
Automatic zero and span checks for system accuracy and daily drift checks.
Multiple integration options with TCP/IP Ethernet, RS485, RS232, and various mA outputs and inputs.

Specifications:

Measurement range: 0-300 mg/m³.
Certification range: 0-7.5 mg/m³, with supplementary ranges up to 300 mg/m³.
Long-term zero drift: less than 0-1 mg/m³.
Stack temperature range: -20°C to +250°C, with an option up to +500°C.
Ambient temperature range: -20°C to +55°C.
Stack/duct diameter: up to 3 meters.

Sensor Specifications:

Material: 316 Stainless Steel / Hastelloy® for corrosion resistance.
Enclosure protection rating: IP66.
Weight: 1.5 kg for the standard sensor.
Local output: RS-485 connection to control unit.
Power requirements: 24 V DC provided by the control unit.
Air purge requirements: Continuous air purge of 50 L/min.

Certification:

Gas Zone: Zone 2 with various certificate numbers and codes for IECEx, ATEX, and UKEx.
Dust Zone: Zone 21 and 22 with corresponding certifications.
