The IM-781 instruments have been designed especially to measure the EGT in Rotax® engines 912.
 

The IM-781 is available in 57 mm diameter

With  a optional switch, you can measure the Temperature of two EGT.
 

The instruments use a pointer thats turns 240º, witch gives them great resolution.
 

Their display areas are divided  into red, green and yellow zones in line with the ROTAX limits.
 

Thanks to embedded operational amplifiers, this
 instrument has a high accuracy, but needs a power
 supply of 12V or 24V.
