CEM AT-9955 Professional Digital Automotive DMM Tune up Meter with IR Laser Thermometer

This is a brand new CEM AT-9955 CE certified digital automotive DMM. This top-of-the-line device features duty cycle measurement and dwell angle measurement for 1 - 8 cylinder engine, up to 12,000 RPM. This meter also measures temperature, resistance, capacitance, pulse width, frequency, AC/DC voltage and current.

An IR laser thermometer is also included to allow precision measurement from distance. The IR thermal meter is ideal for measuring component temperature such as engine and transmission box while the K-type temperature probe allows the exhaust air temperature to be measured. A heavy duty carrying case is also included for the protection of the device and your convenience.
