ENM’s series T56 LCD Vibration Activated Hour Meter. The hour meter features 6-digits with an hour glass icon as a running indicator. This unit operates only when it is introduced to vibrating equipment.
This meter can be installed anywhere on equipment with no special wiring connection or power source to operate. The internal battery supplies all the necessary power for the gauge to operate for years of service. The total operating hours are always shown on the LCD display.
This compact tamper proof meter is 100% encapsulated with potting compound enabling it to operate in even the most extreme conditions.
have had the ENM unit installed about 9 years. The battery final died. I have mine mounted with adel clamps on the motor mount of my I J-5. I have a friend that his is mounted on the instrument panel of his Champ. Both installations work great. I only have about 200 hours on the J-5 so I will mount ENM on a small fan and let it run for a couple of weeks to get the hours on the new unit back to 200. It is a simple effective device.
The hour meter works well I would have given it a 5 rating, except for the length of the wire. I connect a toggle switch in the wire, to assure that the hour meter only records when the engine is running and not when another vibration occurs. The wire on the back is so short that it is going to be problematic to install a toggle switch. The first ENM vibration activated hour meter I ordered several years ago had a longer wire and allowed for much easier installation of a toggle switch in the line.
It took quite a while (about two weeks) but the return of the item in exchange for a new one was good.
Lasted for almost two years then the battery died.
The internal battery is supposed to last 8 years (as marketed in the description), the hobbs meter died after about a year and a half. We were told the item only has a warranty for 1 year despite the claims made about its longevity. Dont waste your money.
Lasted 1.5 years then died.
Did not work. Clip the wire loop on the back to activate, is what it says. Did that. Cable-tied to the airframe. Over an hour on the airframe since then and the meter is still zeroed.
T56C1 7/2019 Installed in APR2020 and it stopped at 345.5 in JUN2021. Fine print on data sheet says one year warranty. Obviously their battery life is limited.

This meter is based off of vibrations. If the vibrations caused by moving the aircraft are great enough to simulate engine vibration then yes, the hour meter will begin running.
No wiring is required.
Thank you for providing this information, we will post it for other customers.
Yes that is correct.
This is for experimental aircraft only.
This model cannot be set to existing time. We do offer part # 10-07370 which can be set. However, please keep in mind part # 10-07370 is not vibration activated.
Per Vendor: "Sorry, no. These units have potting compound sealing them for environmental protection making the battery non-replaceable."
