SI2103 Ammonia (NH3) Gas Concentration Analyzer

Ammonia gas（NH₃）Gas concentration analyzer

●Fast, continuous, and real-time measurement

●Ultra high sensitivity, precision, and accuracy

● Good long-term stability, no need for frequent calibration

● Measure water（H₂O）And carbon dioxide（CO₂）To calibrate and validate

● Small size, can be deployed in the field or laboratory, no consumables required

PicarroSI2103The gas concentration analyzer has achieved high-precision and stable ammonia gas analysis（NH₃）Measurement. The analyzer has high sensitivity and a detection limit ofpptLevel, high stability, and negligible drift from one month of continuous work. Coating on important gas channels（SilcoNert ®）Can be reducedNH₃The adsorption tendency of molecules on the channel surface improves the response time of measurements and eliminates measurement bias. Extra carbon dioxide（CO₂）Measurement values are used forproxy authenticationSimplified and replaced the complex calibration process of standard gases (refer to page 2).

For ammonia gas that requires real-time response measurement (Figure)1）And/Or applications with high sensitivity and stability,PicarroAn analyzer is an ideal solution. These applications include but are not limited to urban and atmospheric air quality monitoring, particulate matter formation research, quantification of livestock emissions, quantification of vehicle emissions, indoor air quality, etc. The analyzer has a small size and low power consumption requirements, and can be disassembled and assembled within a few minutes (whether in the laboratory or in the field).

SI2103The analyzer can run for several months without user interaction, and the concentration trend data is continuously archived on the internal hard drive of the analyzer. And it can be achieved through EthernetRS-232Interface, analog signal4~20 mAperhapsModbusAutomatically export measurement data output.

PicarroCavity decay spectroscopy technology（CRDS）It combines many advantages, such as high precision, accuracy, low drift, and ease of use.

*The Picarro analyzer does not require zero point standard gas or zero point reagent kit to operate or meet specifications.

**When conducting span measurements, the measurement interval will be increased to twice the listed parameters.

***Each purchase of an analyzer comes with specifications and a test report (certificate of conformity) for the instrument.
