These units are the most economical TSO?d units on the market. They feature precision, solid state sensors and circuitry to give unequalled performance for the money. They are compatible with avgas, jet fuel, engine oil and many other fluids. Because they have internal voltage regulation, they are compatible with indicating instruments that do not have precision output voltages. Units for fuel and oil pressure are certified under TSO C47. Units for manifold pressure are under TSO C45a. |
