Indoor Air Pollution Meter

To improve the ease and accuracy of field-testing, Aprovecho designed the Indoor Air Pollution (IAP) Meter. The ultra-portable, small-size meter can be worn in a backpack with a sampling point near the nose and mouth of the user. The resulting carbon monoxide (CO) and particulate matter (PM2.5) measures give us an accurate assessment of personal exposure.

The IAP Meter is intended to be easy to use, requiring little training or specialized skills. A sample rate switch allows the user to measure an air sample every 10 seconds, every minute, or every 10 minutes. These measurements are automatically stored in an SD memory card for later transfer to a computer. No connection to a computer is necessary to launch or read the meter, and the accompanying automated data processing and analysis is straightforward. The IAP Meter can log data for up to 30 days.

 

The IAP Meter generates scientifically valid data when used for the following standard procedures:

Water Boiling Test (WBT) – This controlled test takes place in a laboratory or test kitchen; different stove models are measured in the same room.

Controlled Cooking Test (CCT) – The tester asks local cooks to prepare a common meal on both the traditional and improved stoves while measuring the air quality in the room or the exposure to the cook.

Kitchen Performance Test (KPT) – Once a stove design performs well in the WBT and CCT, a KPT is performed on stoves that have been disseminated. In this test, a random sample of cooks with the new stove are asked to allow air quality or exposure measurements for several days at a time before and after installation of the new stove. In this way, real-world use of the stove is measured without tester intervention.

The IAP Meter is calibrated against and has been shown to produce readings as accurate as a nephelometer, a device used in high-level laboratories. These light-scattering PM measuring instruments favor particles of a smaller size, effectively measuring PM2.5 and below.

Software

Data is taken on a SD card for processing later when back from the field. Processing software consists of a simple spreadsheet that incorporates and processes data. We offer two versions of the spreadsheet:

IAP Meter Processing v. 11.11
This spreadsheet contains Macros. It requires PCs with Microsoft Excel, and Macros must be enabled in the Security settings for software to function.  This software can process up to 40,000 lines of data.

The following spreadsheet does not contain Macros: IAP Meter Processing - Macro Free v. 11.11
It is compatible with PC, Mac, and Linux with Microsoft Excel or other similar spreadsheet software. It can process up to 10,000 lines of data.

 

Ofrecemos las mismas ojas de cálculo en español.  La primera contiene Macros y nececita un PC con Excel para funcionar. Puede procesar 40,000 lineas de información.  La segunda no contiene Macros y puede funcionar con PC, Mac, o Linux.  Procesa 10,000 lineas de información o menos.
