About AIRSPACE technology

Finally, dangerous gas monitors you can afford to own!  AGS™, (Advanced Gas Sensing) technology was developed by Airspace on a solid state (no moving parts or chemicals) platform.  That technology offers significant advantages over previous technology;

  1. A constant status check confirms the sensor is functioning.  That feature eliminates the hassle; expense and liability of routinely bump testing to look at the sensor as is required with every other portable monitor.
  2. No calibration is necessary.  In fact, Airspace guarantees their sensor will hold its calibration for five years.  If it should wander in that time, they will replace it without charge.
  3. Airspace offers the industry’s only five year warranty.  Every part of the monitor is warranted for five years, except the AA batteries that power it.
  4. The monitor self manages.  Training is reduced to sliding on the switch and waiting a few seconds for a green status light.  The green status light is confirming the sensor is functioning, the electronics are good and the sensor has a good “zero” – all automatically. 
  5. Airspace monitors self “zero”.  Contamination, for example, is probably the most common problem encountered by sensors – resulting in frequent need to recalibrate in older technologies.  Airspace monitors will burn off most contamination and return itself to zero – automatically.  During that time the monitor will make you aware there is a problem.  Simply make sure it has good batteries and place the monitor in clean air for a while – no re-calibration necessary.
  6. All sensors, including Airspace AGS™, can be overwhelmed by some contaminants – holding a monitor in the exhaust of a vehicle, for example – or spraying with alcohol or silicone based cleaners.  Again, Airspace monitors will tell you it has been damaged when you turn it on – you don’t need to bump test to find that out.  In most cases it will clean itself, but, like any sensor, it can be overwhelmed by mishandling, we don’t want to mislead you about that.
  7. Airspace technology stores without degrading.  A specially designed case allows atmospherically neutral storage.  That ability will eliminate a large percentage of the problems other monitors experience from degradation and contamination while not being used. 
  8. The AI-1201 dual gas model is an exceptional value at about $500.00.  It is constantly looking for carbon monoxide and flammable gases.  Airspace calibrates the LEL side of the monitor to methane since that can also be a silent gas, but it will “see” most of the hydrocarbon gases like; gasoline, natural gas, propane, hydrogen, acetylene, etc.  The ppm reading won’t be accurate except for methane, but the ability to see if the ambient air is saturating with an explosive gas and monitor the trend can be lifesaving for first responders and others working around those gases.
  9. Airspace monitors are not disposables.  At the end of the five year sensor life a new sensor can be installed at a cost of approximately $150.00 and will carry another five year warranty.  That feature brings your costs of ownership down even more dramatically.

Details about the products


The AI–1100 monitor is a basic detector.  It was designed to be a simple and inexpensive alarm medical first responders could simply carry on every call.  It sounds a mild alarm at 30 ppm CO, a more aggressive alarm at 60 ppm and a full on alarm at 120 ppm.  It alarms with an LED light and 92 decibel audible alarm.  Like all our monitors it carries a five year guarantee including the sensor, and only requires AA batteries so it’s very inexpensive to own.  Also, all of our monitors operate automatically, continuously monitoring the electronics, current flow through the sensor and self zeroing.  Our technology is the only one that can confirm the electronics are good, the sensor is functioning and you have a good “zero” by a green status light on the sensor.  No routine bump testing or calibration is required.  The operator simply turns it on and checks for a green status light.

The AI -1200 monitor adds a faster update and an LCD readout screen.  It includes all the self management and warranty features of the 1100 monitors.  The 1200 monitor gives very precise information to allow the responder to deal with the CO while there.  In smaller departments it can multi task as a tool for overhaul and Co alarm response for the Fire Department.  That monitor updates every four seconds so it’s capable of checking out the basement, furnace area, tracking a trend as appliances are shut off, windows opened, etc.  

The AI-1201 model includes all the features of the 1200 and adds the ability to find methane and most hydrocarbon gases.  It automatically toggles back and forth looking for flammable gases and then CO.  It can track one or both at the same time updating each gas every four seconds.  This monitor can provide life saving coverage to medical and other first response teams who might inadvertently enter an environment with an ambient air saturation of CO or a flammable gas.  We calibrate the flammable gas side of this monitor to Methane since it can also be a silent gas and is the major ingredient in natural gas.

The AI-1400 monitor senses HCN (Hydrogen Cyanide) gases.  HCN is a by product of burning organics and plastics.  HCN is readily absorbed and then off gases over time so it is a danger in, around and after most fires.  It can be a factor in rehab facilities since bunker gear on firefighters and rescued victims bodies and clothing can off gas HCN which can build over time.  Pump operators, command - anyone around a fire and those who come after should be monitoring for HCN.  Like all of our monitors no routine bump testing or calibration is required and the three year warranty does cover the sensor.

Real world Examples of use in EMS


Ripon, WI in the summer of 2010;   Paramedics were called to rescue several teens who called 911 extremely ill.  They acknowledged they had been drinking. Airspace CO monitors alerted the paramedics to the presence of Carbon Monoxide.  The care to the teens was redirected and a search of the home found the parents asleep and unresponsive.  This call would very likely have resulted in a dramatically worse outcome if the team did not have CO monitors with them.


Mishicot, WI in the winter of 2010;  An EMS crew responding to a call from a late 50’s male experiencing a heavy chest and difficulty breathing were alerted to CO upon entry by the Airspace CO monitors they carry into every call.  More appropriate care was given to the patient – and more importantly everyone was evacuated from the home without further harm.  Very high levels of CO were later found due to a furnace vent begin blocked by snow and ice.


Marshfield, WI in the winter of 2011;  An EMS crew responded to a call from a late 50’s male experiencing a heavy chest and difficulty breathing.  The crew had just received new Airspace CO monitors.  They were not expecting the CO alarm upon entry to the motel room.  They were able to evacuate the building before anyone else was affected, a better outcome was achieved for the patient who was able to get more appropriate care – and none of the crew was exposed.  The CO reading was in the 400ppm range.


Stevens Point, WI, Spring 2011;  An EMS crew responded to a call from a grandmother reporting an ill grandchild.  Upon entry the Airspace CO alarms alerted to Carbon Monoxide.  Without alarms the rest of the family would have very likely be left to sleep in that CO environment.


These examples, all in the last year, only among Airspace customers and just in Wisconsin, illustrate the advantage and the need for carrying CO monitors.  It’s almost a certainty a career Fire Fighter who is on a “first in” team is going to encounter carbon monoxide poisoning in that career.


Before the availability of Airspace Monitors there may have been an argument that the cost and complexity of maintaining electro chemical monitors was prohibitive for this use.  The low cost of maintenance and simplicity of the Airspace Monitors reverses that argument – can you afford not to protect your people?
