0024-0788 Oxygen Sensor, 2-year by Bacharach

The O2 sensor is used in Bacharach portable combustion analyzers to measure the percentage content of oxygen levels in flue gases. The range of the oxygen sensor is 0 – 20.9%. O2 measurement is used in conjunction with the chosen fuel to calculate the CO2 levels in flue gases. Bacharach portable combustion analyzers only calculate CO2 when oxygen levels are below 16%. Bacharach uses O2 and other readings in determining efficiency rather than CO2 for a more accurate measurement. Measuring oxygen content in the excess air lets you know if you have too much air or too much fuel, allowing you to tune your furnace or boiler to maximum efficiency. Measuring O2 directly can save fuel, and save time during a combustion tune-up test.

• Measures percentage content of oxygen levels in flue gas
• Provides more accurate efficiency readings
• Saves time during tune-ups, telling you if air or fuel is too high
• Available in two year, three year, and five year sensor life depending on instrument

1295-0552 Chemcassette Tape, Sulfur Dioxide by Honeywell Analytics

Chemcassette® is the unique trademarked name for a calibration free toxic gas detection method that uses an optical scanning system to detect the presence of gas by a colour change on the specially chemically impregnated paper tape. Chemcassette® technology is highly specific and reacts extremely fast to the presence of parts per billion (ppb) levels of many hazardous gases. Over 200,000 points of gas detection are currently maintained by the Chemcassette® sensing technology at any given time around the World in some of the most critical safety applications possible.

Each Chemcassette® is manufactured to traceable ISO 9000 manufacturing standards by a world class team of highly trained chemists and each batch is calibrated with ultra pure gas that is traceable to nationally accepted standards. This means that the end user does not have to provide calibration facilities themselves thereby saving cost and reducing risks to their own staff.

Efficient high volume manufacturing techniques means that there is always available Chemcassette® in stock that can be shipped anywhere in the World so that our customers are never left without adequate safety cover. Application support with expert gas detection chemists is available by phone and e-mail and is supported with many years of technical application notes and help to diagnose common support issues.

Should there be any concern regarding the performance of an individual Chemcassette®, a free of charge evaluation will be performed to trouble shoot the observed scenario using the award winning quality management system "Customer Discrepancy Report" CDR. Every CDR completed by a customer is guaranteed a full response and the outcome is reported directly back to the end user to ensure a complete resolution process.

Each Chemcassette® is backed with a full warranty and we have over 20 years of experience regarding the quality control of our proven sensing technology.

Additional Features and Benefits:

• Visible proof of a gas release event
• Greater sensitivity (detection down to parts per billion levels)
• Superior selectivity (less cross-interference with other gases)
• Fast response time
• Low false alarm occurrence
• Stability (consistent, repeatable operation)
• No calibration required
• Easy to use
• Available in fixed and portable instrumentation

1388 IR Temp 310 Infrared Thermometer by Wohler

The Wohler infrared thermometers make it easy to determine the temperature of surfaces and inaccessible areas. The IR Temp 310 also offers a number of other functionalities. Both thermometers measure the temperature by detecting infrared radiation even at greater distances and show the temperature on their display. The emission factor can be easily changed in the menu to always obtain the most accurate measurement. A visual laser beam helps to accurately detect the area to be measured.

The IR Temp 310 also offers the possibility to store the data of the measurement in the device and to connect an additional thermocouple. Furthermore, it also assists in assessing the indoor climate and the potential for mold growth by measuring the relative humidity and wet bulb temperature. The laser measuring circuit provides precise information about the measured range.

Both measuring devices allow adjustable temperature limit values with alarm function and are ideally suited for surface temperature measurement.

• Display of surface and dew point temperature with indication of the mold risk potential
• Adjustable temperature limits with acoustic, visual and vibration alarm
• External temperature sensor can be connected (e.g. surface temperature sensor, temperature sensor for determination of the specific emission factor)
• Display of relative humidity and wet & dry bulb temperature
• Measuring range visualization by laser measurement circle
• Storage of 50 data sets (including emission factor)
