TM Series hourmeters record the operating time of vehicles or powered equipment.

They are electromechanical and have a quartz base time counter that ensures accuracy (better than ±0.02% over the entire range). They can record up to 99,999.9 hours and include an automatic recycle to zero hours feature. The TM Series models have a shock-proof and tamper-proof, totally sealed case made of engineered plastic. These small, lightweight time meters are rugged and durable. They are the answer to applications requiring a low DC power and reliable hourmeter. These hourmeters can be used on any engine where operating time needs to be recorded. All it requires is a DC power source (see specifications).
