CEA 700 - Range of 0-10,000 ppm - Affordable, hand held units that monitor up to 10,000 ppm (1%) of Carbon Dioxide and Temperature readings in ^oF or ^oC. These units are durable, reliable, and extremely easy to use and maintain. Each unit is equipped complete with a large digital display, AC power adapter, and flip out stand. Standard alkaline batteries last up to 80 hours for portable use. Other unique features are included such as adjustment for altitude changes. There is no built-in air pump, backlight, alarms, or internal datalogger.

TRIPLE PLUS + - Range of 0-2% Volume (Infrared Technology) - Multi-gas unit that simultaneously monitors, displays, and alarms for one to four gases with many different interchangeable, 'smart' electrochemical and Infrared sensors available. These units are housed in an ultra durable case that is virtually unbreakable, highly water resistant, dust proof, and RF resistant. This is the only unit that would float if dropped accidentally in water! The large digital display with backlight shows the levels of the gases and the push button menu for the advanced microprocessor's features which is password protected. There is the option of a built-in air pump, internal datalogger, and more.

GD-888 Series - Ranges of 0-10,000 ppm (1%), 0-10% Volume, or 0-100% Volume - AC/DC units available to monitor Carbon Dioxide with a backlit LCD display, built-in air pump, push button controls, adjustable alarm, recorder output, and a battery charger that is also the continuous AC power supply. The rechargeable batteries allow up to eight hours between charges. The optional datalogger can store up to 1,000 readings along with time and date using easy Windows^TM software.

RI-555 - Ranges of 0-2% Volume to 0-100% Volume - Transportable, AC powered, non-dispersive infrared analyzer with a built-in air pump and autoranging digital display for diverse dual, resolution of different gases in the high percentage volume levels. An alarm and choice of outputs are available but there is no option of an internal datalogger.

CEA 266 - Ranges of 0-2000 ppm to 0-20% Volume - Wall mounted, industrial strength Carbon Dioxide analyzers contained in a water resistant and dust tight fiberglass enclosure with digital display. Standard ranges of 0-2000 ppm, 0-5000 ppm, 0-1%, 0-2%, 0-5%, 0-10%, and 0-20% are available. The sample gas is continuously drawn into the unit through a built-in air pump. A self-draining water trap and dust filter are also provided. The unit has 0-5 VDC and 4-20 mA linear outputs, as well as high and low level audio/visual alarms with accompanying contact relays.

CEA 144 - Ranges of 0-2000 ppm to 0-5% Volume - Wall mounted, affordable Carbon Dioxide monitors that weigh under 2 pounds and are contained in a steel enclosure. All units are equipped with digital display and both 0-1 VDC and 4-20 mA outputs. Standard ranges of 0-2000 ppm, 0-5000 ppm, 0-2% and 0-5% are available as well as an optional relay contact. This unit requires calibration only once a year and was designed for industrial and commercial applications that require reliable performance in a rugged package at a competitive price. With its broad range of input voltages and low power consumption, this flexible monitor is easily incorporated into a broad range of applications. These units are standard for diffusion monitoring but are available as a flow through version.

CEA 700 - Range of 0-10,000 ppm - Low cost, hand held units that monitor up to 10,000 ppm (1%) of Carbon Dioxide and Temperature readings in ^oF or ^oC.

MGA 3000 - Ranges of 0-10 ppm to 0-100% Volume - Single or multiple gas analyzers that use advanced Infrared and several other field proven technologies to analyze up to four gases at once. These units with built-in air pumps can be used in hostile or friendly environments. The option to upgrade at a later time protects your initial investment. A robust, attractive, compact 3U rack mount enclosure houses the unit with an optional bench case available for non-rack mounted applications. Many different gases from low ppm to 100% Volume levels can be analyzed and monitored
