TM Series Hourmeters
- 2 in. (51 mm) diameter dial
- Tamperproof and environmentally sealed
- Mechanical counter – no battery needed to maintain elapsed time
- Reversed polarity protected
- Quartz-crystal time base for accurate long-term timekeeping
- Powered by 12 to 24 VDC
Description
The TM Series hourmeters record the operating time of vehicles or powered equipment. They are electromechanical and have a quartz base time counter that insures accuracy (better than ±0.02% over the entire range). They can record up to 99,999.9 hours (9,999.9 for TM612/624) and include an automatic recycle to zero hours feature. The TM Series models have a shock- proof and tamperproof, totally sealed case made of an engineered plastic. These small, light weight time meters are rugged and durable. They are the answer to applications requiring a low DC power, reliable hourmeter.
The TM612/624 model includes a 3-hole mount- ing shock ring for extreme-shock protection.
