The app has been developed by the Engineers of CES Environmental Instruments, one of the UKs leading environmental Test Houses and incorporates some of their on-site calculations in one easy to use app.

When working on the stack and you need that quick answer to a gas conversion or probe position, the answer can be at your fingertips. Simple and easy to use the app contains lots of essential calculations for the stack tester without the need to manually calculate the value or start up a laptop. The app is an essential tool for the professional Environmental engineer having all the tools to quickly check the numbers whilst out and around site.

The contents of the CES Environmental Instruments popular Engineers Note Book is preloaded within the app.

The app can do the following and much more:

- Calculate Dia, CSA, Circ.
- Isokinetic sample positions, General & Tangential
- Extraction rates
- Gas density
- Calculate H20 from wet & dry Oxygen
- Gas ppm/mg/m³ conversions & Normalisation
- LOD
- Particulate Matter Normalisation & estimation of temp, H2O & O2
- Ranging & scaling of dust monitors & outputs
- Calculation of values using calibration functions
- Biomass fuels
