Ambient Ion Monitor (Model 9000 Series)

The 9000 Series Ambient Ion Monitors consist of four configurations.

The URG-9000A Ambient Ion Monitor (AIM) provides time-resolved direct measurements of anion particulate Nitrate, Sulfate, Nitrite, Phosphate and Chloride found in PM-2.5. Nitrite and Sulfate aerosols are produced as a result of the interaction of ammonia (NH3), NOx, SO2 and other gaseous constituents. These ions can represent a significant portion of the PM-2.5 and are important in understanding visibility degradation, atmospheric chemistry and inputs into various ecosystems.

The URG-9000B Ambient Ion Monitor (AIM) has an additional Ion Detector to allow for time-resolved direct measurements of cation particulate Ammonium, Sodium, Calcium, Potassium and Magnesium in addition to the anion particulate.

The URG-9000C Ambient Ion Monitor (AIM) provides time-resolved direct measurements of anion gases Hydrogen Chloride, Nitric Acid, Nitrous Acid and Sulfur Dioxide in addition to the anion particulate.

The URG-9000D Ambient Ion Monitor (AIM) provides time-resolved measurements of ammonia in addition to the anion gases, anion particulate and cation particulate.


All URG analysers are sold with 1 years parts warranty as STANDARD.

The warranty can, at additional cost, be extended for total peace of mind. Please call to discuss options for this.

URG analysers require periodic service and maintenance to both satisfy the requirements of the warranty and to ensure that the highest possible data capture rates are maintained.

Enviro Technology has a large team of in-house and field based service engineers who regularly receive “factory training” and can provide the very best levels of service and support.

Enviro Technology and URG recommend that the Ambient Ion Monitor 9000 Series is serviced every 6 months of continuous operation.

A wide range of servicing options are available and can include:

- Pre-scheduled on-site planned maintenance (every 6 months).

- Emergency on-site call-out within agreed timescales (i.e. 48 hours).

- Supply of consumable items (i.e. sample inlet filters).

- Supply of calibration gases and permeation tubes.

- Supply of permeation tube calibrators and zero air generators

- Remote analyser “health-checks” and diagnostics.

- Return-to-base servicing options.

- Local site operation services.

- Data collection and data management services

Please contact either our sales or customer services teams to request a quotation for on going servicing and maintenance on this analyser.
