Simpling  Exhaust
direct sampling, the length of the sampling tube is 5m, the length of the sampling probe is 900mm
Oil temperature: temperature measurement inserts into the oil gauge hole of the engine, insert length is same with the oil gauge, blocked with rubber plug to prevent oil smoke
Wire length: 5m;
Speed: fix the folder of tachometer on the high-voltage soft-line the of gasoline engine to measure the speed.

Display Mode 
High-brightness LED display    Large LCD display

Optional configuration
 temperature, speed configuration

Main functions
 Printer built in(temperature, speed configuration) , Communication with the computer network, 30 minutes automatically prompte to zero. Idling and dual idling two measurement methods, built-in clock module to display time, number plates can be stored 500 sets of measurements data, natural gas, liquefied petroleum gas and gasoline these three fuels to choose.
