Bacharach 0024 7221 ECA 450 Combustion Gas Efficiency & Environmental Analyzer

The Bacharach ECA450 can determine burner efficiencies of boilers, furnaces & other types of commercial combustion equipment, enabling plants to reduce fuel cost while monitoring and determining pollutant levels. 

The Bacharach 0224-7221 combustion gas analyzer features the most user friendly interface available and delivers sophisticated combustion measurements with ease. It is also ETV / EPA test verified to NOx emissions to ensure more precise measurements, while conducting accurate emissions and combustion testing. This enables you to meet strict environmental regulations & ensure that your combustion equipment burns efficiently. Bacharach's ECA 450 has the capability to measure carbon monoxide, oxygen, sulfur dioxide, nitrogen dioxide, nitric oxide, combustibles, draft and temperature. It can also calculate combustion efficiency, NOX, carbon dioxide and excess air.
Take continuous test samples of boilers, furnaces & other combustion equipment in industrial environments for 8 hours & generate reliable, precise combustion & environmental calculations and measurements. This highly accurate, detailed test data will then allow accurate adjustments to your equipment & improve pollution level evaluation which improves combustion efficiency overall, reducing fuel costs & determines your emissions compliance.
Modular Sensors & Upgrade Capabilities - The ECA 450 has an innovative modular design which allows upgrades your instrument to include additional sensors when your measurement & testing data requirements grow. The base model includes 2 sensors, one which can measure oxygen & another can measure hydrogen-compensated carbon monoxide. Your 0224 7221 can easily & quickly be upgraded to incorporate any combination of optional sensors - (high) Carbon Monoxide, Sulfur Dioxide, Nitrogen Dioxide, Combustibles, Nitric Oxide.
Enormous data storage capabilities – Allows tracking of 1,000 maximum test data records. This enables you to store accurate test result histories, download them to your computer, recall them to the display and / or print time & date coded records for later reference.
Microprocessor based test instrument featuring front panel control - Menu driven, and also provides you with access to all major display screens with just 1 button push on the front panel. Memory, Pressure, Fuel, Calibration and Setup have their own dedicated buttons. No matter your location in the simple menu structure, access to these features is a simple button push away. Set your instrument to be customized to your preference. Get the test data you require in the format you desire with a few easy button pushes.
Customized Setup Examples
  • Selectable temp. units (F or C)
  • Selectable units for pressure (mb, H2O, inches, hPa, Pa)
  • Selectable languages (English, Spanish, French)
  • Selectable units for pollution (ppm, Lb / Mbtu, mg / m3, g / GJ)
  • Data display ordering
  • Keypad sounds
Customer & user data can be tracked and cataloged, which allows the storing of test data records by customer to keep running histories. You can also customize your customer's data reports with your company's name, address & phone number.
Software Calibrations - Make calibration adjustments as needed, in the field, using a few easy button pushes on the front panel. Potentiometer adjustments are not needed. Calibrations are password protected, so after your password is verified, you are able to calibrate any combinations of your measurement channels. If calibration fails, the ECA 450 will alert you of the improper calibration & new settings won't be accepted. It will also automatically zero all sensor channels for ambient air as it is powered on. When a sensor remains in error while warming up, the unit automatically warns you of the problem. Calibrations are still advised every 6 months or earlier if needed.
