The Hobbs Engineering Company SW-1179 Quartz Interruptable Hour Meter is a device designed to measure engine hours for aviation applications. Here are some pros and cons of buying this hour meter:
Pros:1. Quartz Technology: The SW-1179 hour meter utilizes quartz technology instead of the traditional mechanical contacts, making it more reliable and accurate. A quartz hour meter is less susceptible to the wear and tear that comes with repeated engagement and disengagement of the contacts.
2. Interruptable Feature: This hour meter has an interruptable feature that enables easy installation and removal from the wiring harness. This is useful during maintenance inspections or during the process of repairing or replacing other avionics.
3. Battery Backup: The SW-1179 hour meter has a battery backup, ensuring that the hour data is not lost in case of a power failure.
4. Low Profile Design: The meter has a low profile design, making it ideal for installation in confined spaces or in applications where space is limited.
5. Easy to Read Display: The digital display is easy to read and provides accurate and reliable hour readings.
Cons:1. Cost: The Hobbs SW-1179 hour meter is more expensive than some other hour meters on the market. It may be a significant investment for smaller aviation operations, especially for those with limited budgets.
2. Complex Installation: The hour meter's interruptable feature requires a more complicated installation process than a straight-through hour meter. It's recommended that installation be performed by a certified avionics technician.
3. Limited Compatibility: The SW-1179 hour meter is designed for specific aviation applications, and it may not be compatible with all aircraft models or wiring configurations. It's important to verify that the meter is suitable for the specific application before purchasing.
Conclusion:The Hobbs Engineering Company SW-1179 Quartz Interruptable Hour Meter offers several advantages in terms of accuracy, reliability, and convenience. However, it also comes with a higher cost compared to traditional hour meters and requires a more complex installation process. In applications where high accuracy and safety are a priority, such as commercial aviation or large private aviation operations, the investment in a quartz interruptable hour meter could be worthwhile. Smaller aviation operations or those with limited budgets may prefer a more affordable solution. Ultimately, the decision to purchase the SW-1179 hour meter should be based on the specific requirements, budget, and wiring configuration of the aviation application.
