Specifications:
The document outlines the technical specifications for a measurement system by 15DXG Ltd. It includes dimensions (W300 x D420 x H413 mm), weight (20 kg), and power supply requirements (110/220 VAC, 50/60 Hz). The system is designed to operate under conditions up to +450 °C and has an IP65 (IP66) enclosure rating.

System Components:
The system comprises a main unit, probe, power distribution panel, purge motor unit, master flange, and cables. Optional components include a probe protector and a Teflon-coated probe.

Technical Specifications:
The system uses Tunable Diode Laser Spectroscopy (TDLS) to measure NH3 with a minimum measuring unit of 0.1 ppm and a response time of less than 5 seconds. The measuring range is from 0 to 500 ppm. The system ensures high accuracy with zero drift and span drift within ±1% FS over 2 hours.

Communication and Interface:
It supports multiple communication channels including RS232, RS422, RS485, LAN (Ethernet), and Hart. The system provides 2-channel and 4-channel analog outputs (4 ~ 20 mA).

Features:
The system is designed for semi-permanent use without the need for light source replacement, utilizing a laser light source. It includes a calibration filter for standard gas calibration and incorporates SUS material to prevent damage from particles.

Environmental and Operational Conditions:
The system operates within a temperature range of -20 to +55 °C and includes a 7" LCD monitor with a touch screen for display and input. The power consumption is 500 W.

Additional Specifications:
The probe is made from SUS 316L or SUS 316Ti materials, with an adjustable length of 0.5 to 2.5 meters. The necessary gas flow rate is > 1 m/s, and the purge motor analyzer consumes 0.5 ㎥/h of instrument air.
