The SHAW pressure dewpoint calculator is extremely handy and perfect for onsite visits and spot check reading conversions. It stores easily in the carrying case alongside your portable dew point meter and is always ready to use, even in hazardous areas.

One side of the pressure dewpoint calculator displays any dewpoint temperature at any given pressure. Here, you can calculate and/or convert your dewpoint temperature reading to the equivalent dewpoint temperature at any other pressure and view trace moisture content calculations in parts per million (ppm(V)).

The reverse of the calculator displays easy conversions for dewpoint temperature in a table format. Use this side to convert your trace moisture measurement to any of the following units:

• °C - degrees Celsius
• °F - degrees Fahrenheit
• g/m³ - equivalent moisture levels in mg/water per litre
• lb/MMSCF - lb/water per million cubic feet
• ppm(V) - parts per million water vapour by volume
• pascals - water vapour pressure

A quick reminder, all conversions from our pressure dewpoint calculator are based on ideal gas behaviour.
