Add Oil Detection Unit
This unique piece of technology is designed to let you know when you need to add oil to your engine, without entering the engine compartment.
Don't depend upon the oil light to come on to know when to add oil to your engine. This is a low pressure light which means you are out of oil. Continued use of the engine will cause serious and expensive damage.
The test unit uses a probe to sniff for fluids. Upon the detection of fluid, a signal is transmitted to the pilot station, notifying the operator that the fluid level is within specified parameters.
- Consider the sense of comfort knowing that the oil level is always correct prior to starting your engine.
- That damage and costly repairs won't occur due to an overlooked obligation.
- This information can be transmitted to you, in the cockpit or any other location, with a turn of the ignition key.
- The unit fits any engine, which uses a dipstick to check its oil level.
- It works like a dipstick with no mechanical parts entering the engine, thus no risk of damage to the engine.
- It installs without any modifications to the engine and can be done within minutes.
- This system is self-checking and carries a 2-year warranty. Simply return the test unit and proof of purchase. We'll gladly send you a replacement (provided the test unit has not been tampered with).
- The unit consumes 12 Volt DC 15 amps.
