MESSKO® COMPACT

Modular temperature measuring system with direct display

MESSKO® COMPACT series devices prove their quality under extreme climatic conditions. The closed system allows measured values to be read off clearly even after decades – without readjustment or recalibration. The pointer thermometers with adjustable micro-switches reliably measure the oil and winding temperature (thermal image) in distribution and power transformers, reactors or similar applications. The mechanical measuring system functions without power and the compact design integrates all functions, including remote transmission – without any additional devices!
