MEGA-CHANNEL - Model IQ1000 Series -Gas Detector

The IQ1000 is an intelligent, microprocessor based instrument that is operated through easy to follow menu driven controls. The viewing screen is a large 8 line, 40 character per line LCD supertwist display, with backlight switch and display contrast adjustment for easy viewing in any lighting condition.

The IQ1000 furnishes three user-adjustable alarm setpoints (low, mid, high) for each sensor, with both audible and visual alarm indicators. An alarm acknowledgement function silences the audible alarm while keeping the visual alarm active as long as the alarm condition exists.

An optional data logging feature stores months of readings for all four sensors, which can easily be downloaded to a printer or computer at a later date using its RS 232 serial interface. The IQ1000’s optional data management software allows you to plot accumulated data and calculate time weighted averages. Data can also be exported to your favorite spreadsheet.

The IQ1000 will operate approximately 20 hours on its standard six size D alkaline batteries, or 14 hours on optional rechargeable NiCad batteries. The amount of battery power remaining is monitored on the LCD display.

Other features include touch of a button calibration, a built-in sampling pump with sampling wand, and weatherproof case. The IQ1000 also has UL Intrinsic Safety Approval for use in Class 1, Division 1, Group B, C, D.

The IQ1000 can accommodate several kinds of sensor technologies. Which ones to select depends upon your application requirements.

The revolutionary MEGA-Gas Sensor is a specially developed solid state sensor capable of detecting over 100 gases and vapors. While it cannot readily differentiate between these gases, the MEGA-Gas sensor does enable you to perform a “Gas Search’’ of the air, as described above. In addition, because the IQ1000 is microprocessor controlled with 256K memory, it contains a complete library of the setup and calibration parameters for all 100+ gases that the MEGA-Gas sensor can detect. At the touch of a button, you can configure the instrument to monitor specifically for any one of these gases, and can then switch gases as frequently as you like without changing any sensors. See the table on the facing page for the MEGA-Gas sensor gas list.

Any of the more than 140 gas specific Solid State Sensors can be selected to provide more selective gas detection than the MEGAGas solid state sensor.

Electrochemical Sensors, a popular sensor used in many gas detection instruments, can also be accommodated by the IQ1000. Choose from 11 available gases and vapors (ranges in ppm):

• Ammonia (0-50, 0-100)
• Hydrogen Sulfide (0-20, 0-50)
• Carbon Monoxide (0-50, 0-100)
• Nitric Oxide (0-50)
• Chlorine (0-5, 0-10)
• Nitrogen Dioxide (0-10)
• Hydrogen (0-500)
• Oxygen (0-25%)
• Hydrogen Chloride (0-25)
• Sulfur Dioxide (0-10, 0-20)
• Hydrogen Cyanide (0-25)

For combustibles, a Catalytic Bead Sensor is available to detect for LEL levels of most combustible gases and vapors.
While there are hundreds of sensor combinations, keep the following guidelines in mind when customizing your Model IQ1000 detector: Channels 1 and 2 can be equipped with any of the four sensor types listed; Channels 3 and 4 can only be equipped with electrochemical sensors.
