China CGT-165 Projection Magnetic Compass:

CGT-165ProjectionMagnetic Compassis a sort of vertical liquid magnetic compass with excellent performance and reliable working. It is designed and manufactured in accordance with the national standard GB/T 14108-93 (General Technical Terms of Marine Magnetic Compass Class A) and completely accord with the demand and standard of the relevant navigation equipment regulated by ISO449 and IMO. The product has the characteristics of high precision and steady performance and can be used for long time under inclement weather at ship sailing. It has the following characteristics.

1.It is the standardmagnetic compassas well as concurrently acting as steering magnetic compass and overcome the difficulties that the wheelhouse is lack of area for mounting and it is difficult correcting in the steel cabin . It is useful for the arrangement of console.

2.The projective tube is changed directly inserting in the bottom of the compass from the wheelhouse . The advantages of it are simple installation, convenient maintenance and may disassemble the clean imaging glass at any moment.

3.Projection lamp adopts 8W LED light source , its life is over 10 times than traditional projection lamp . The scale of the compass under projection is clear and visible, brightness equality and softness.
