The 3M™ Multi-Gas Detector 740 Series is designed for ease-of-use, durability, convenience and low operating cost. It’s the ideal companion for workers on industrial sites or in confined work spaces – scenarios where potentially hazardous levels of CO, H2S, O2, or combustible gases may be found. |
||
The 3M™ Multi-Gas Detector 950 Series helps take the worry out of workplace monitoring by providing fast, reliable information on the selected target gases. The 3M 950 detector can detect up to five gases simultaneously, and can be used with the powerful 3M Know Your Air software - the software can be used to customize the detector setting to your specific application, download, analysis, and generate reports for up to 5 months of stored data. |

| Use For Monitoring for, either Carbon Monoxide (CO), Hydrogen Sulfide (H2S) or Oxygen (O2). Do Not Use For Monitoring for gases other than those which the instrument was designed to monitor, or in atmospheres where oxygen concentrations are below 12 % when equipped with Carbon monoxide (CO) or Hydrogen Sulfide (H2S) sensors. Prolonged exposure to high levels of target gas may prematurely degrade sensor performance. General Description These User Instructions apply to the 3M™ Single Gas Monitor 110 Series. It is designed to provide continuous monitoring of the ambient environment for Carbon Monoxide (CO), Hydrogen Sulfide (H2S) or Oxygen (O2), depending on which sensor is installed in the instrument. The gas detected by the sensor installed in the instrument is identified on the label located on the front of the unit and the sensor symbol on the LCD display. Accuracy of the instrument’s gas sensor readings can vary up to +25% depending on the accuracy of the calibration gas, how often a calibration (O2) or calibration verification test (CO, H2S) is performed, environmental conditions (temperature, atmospheric pressure, humidity, air velocity), cross interference gases or time of exposure to the target gas (see SPECIFICATIONS section). Calibrating (O2) prior to use in the same environmental conditions as the instrument will be used will increase the accuracy of the instrument’s gas concentration reading (see Calibration Verification Test and Calibration section). An internal microprocessor controls the indication and alarm functions in response to the signals received from an electrochemical sensor permanently mounted inside the unit. When turned on, it continuously monitors the ambient air that enters the sensor through the sensor inlet opening by the process of passive diffusion. If the level of the target gas detected by the sensor reaches a factory preset alarm point, the unit will alarm (see SPECIFICATIONS section). The 110 monitor is a battery powered unit utilizing a permanently mounted, non-rechargeable 3.6-volt Lithium battery. It is designed to be intrinsically safe. The 110 monitor is CSA (US) certified intrinsically safe for Class I, Div. I, Groups A, B, C, and D Hazardous Locations. The components of the 110 monitor are assembled in an ABS/PC plastic housing 3.2 x 2 x 1.2 in. (8.1 x 5.1 x 3.1 cm). Located on the front face of the unit is an ON/MENU button, the display (LCD), sensor inlet, audio alarm opening, visual alarm LED. On the back of the instrument is an alligator pocket/belt clip and a label containing the intrinsic safety information and serial number. |

| The 450 Single Gas Detector is designed to continuously monitor the ambient environment and notify the user if the level of the target gas reaches the alarm set point for the detector. The 450 Detector is available in ten versions to detect : Oxygen, Hydrogen, Hydrogen cyanide, Sulfur dioxide, Hydrogen sulfide, Chlorine, Carbon monoxide, Nitric oxide, Ammonia, Nitrogen dioxide. Gases detected by the sensor installed in the monitor are identified on the label located on the front of the unit. Do not monitor for gases other than the one for which the instrument was designed to monitor or in atmospheres where oxygen concentrations are below 12% (except the oxygen sensing detectors). Prolonged exposures to high levels of the target gas may prematurely degrade sensor performance. The 450 Detector can be fit with a hand pump. To connect the pump to the detector, attach the tubing to the hood. Squeeze the hand bulb continuously. |
||
| 3M also manufactures a range of fixed gas / air monitors under the Macurco name. There are a number of different, specialized monitors for air quality, carbon monoxide, combustible gases, hydrogen, nitrogen dioxide, etc. Some of the monitors are intended for HVAC monitoring, garage, warehouse and maintenance facility monitoring. Some of the units are stand alone monitors and others are designed to work with separately mounted control panels. | ||
