Ammonia Calibration Gas Generator (NH3)

Ammonia gas is a very commonly used toxic gas found in many applications, most commonly the cold storage, petrochemical, wastewater, and chemical industries. If you have ammonia gas at your facility, and there is a possibility that people could be exposed to that gas, you are required to have gas monitors in the area of your facility where the NH3 is stored. To ensure that your monitors are operating correctly, they must be calibrated periodically. ACD's calibration instruments are the best method for generating ammonia calibration gas to calibrate your fixed or portable ammonia gas detectors.

Advanced Calibration Designs are set apart from all other gas suppliers by providing calibration gas standards that are superior to the previous approaches to calibrating gas detection monitors for the health and safety industries.

Simply put, Advanced Calibration Designs calibrators are gas generation devices that are superior to the previous approaches to gas sensor calibration equipment for the health and safety industries.

Advanced Calibration Designs exceed the limitations of all previous forms of calibrating gas monitors. They do this through Integrated and Expandable products that provide the backbone of the new era in calibration gas standards.

Economical Gas Generator Standards

Historically, calibration gas came in the form of cylinders, which have severe limitations.  Cylinders of cal gas are most often filled almost entirely with air, which makes them extremely inefficient.  99.999% of a 10 PPM cylinder of any gas is simply clean dry air. ACD uses the background air at the calibration point to blend with the desired gas which provides enormous advantages.

A 58-liter cylinder provides 58 minutes of cal gas flowing at 1 liter per minute (roughly 1 hour). A single ACD calibration source provides up to 100 times that much gas! 100 hours of gas at the same flow rate. This translates to a rough cost (depending on the gas needed) of approximately $300 per hour when getting your gas in cylinders. Conversely, the cost of 1 ACD 100-hour source is $13.91 per hour of calibration!


Calibration Gas On-Demand

ACD products generate the gas on demand rather than storing it, providing many advantages over the old approaches. Since there is no gas present until the user requests it, and the gas is never under pressure. ACD products are safe for air transport and do not deteriorate over time. It is not uncommon for customers to use the same calibration source for 5, 10 or even 15 years of calibration.

The on-demand generation of the gas allows a single calibration source to generate adjustable concentrations. Cylinders are a single fixed concentration. Most ACD generating sources can provide concentrations of between 0.25 and 125 parts per million. In addition to this, the flow rate can be varied between 0.2 and 1.0 liters per minute using the internal pump. Calibrations of sample drawing gas detectors can be accommodated by the use of the internal mass flow sensor.

Expandable Capabilities for Gas Monitor Calibration

​Our products are integrated and expandable, with a single hand-held product smaller than a 58-liter cylinder, the end-user can have up to 10 different gases and hundreds of hours of cal gas at his disposal. Best yet, your service technician can get on a plane with a single checked bag and be on site ready to calibrate a multitude of different sensors.
