Coming soonFrequently Asked Questions
Are these instrumentation tools free?
Yes. Every tool is free, works on mobile and desktop, and needs no download or sign up.
What tools are available?
Instrument tag decoding, IP, NEMA and Ex marking decoders, wire colour code charts and PID tuning calculators with a PID simulator. P&ID symbols, charts, troubleshooting guides and practice tests are being added.
How is this different from the calculators?
Calculators solve engineering equations. Tools decode, look up and explain field information such as tags, markings, colour codes and tuning rules.
