MESSKO Thermometers

$1,033.17Price
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!
 
The MESSKO® Universal Retrofit Kit is used to replace malfunctioning temperature gauges on transformers, reactors or similar devices. It is suitable for oil or winding  temperature gauges. The Retrofit Kit consists of a gauge  with a mechanical pointer that clearly shows the temperature. 
Depending on the connection the same gauge can be used for either oil temperature indication or for winding temperature indication. A resettable maximum temperature indicator is standard.
