SELFA has a strategic distribution partnership with JUMO in Nigeria.  The JUMO brand has been synonymous with industrial instrumentation products for the sensing, recording and controlling of temperature, pressure, humidity and analytical systems since 1947. JUMO is a worldwide trademark for measurement and control technology from Fulda, Germany.

Temperature sensors for industry, plant engineering, and vehicle engineering

JUMO has been producing high- quality RTD temperature probes and thermocouples since the mid-1960s. Temperatures up to approximately 500 °C are generally measured using RTD temperature probes. The platinum temperature sensor has proven its worth by ensuring high measuring accuracy and long-term stability. Thermocouples are used for measuring higher temperatures. Here, thermo- couples of type L, J, K, N, S, or B are used depending on the requirement. The in-house DAkkS lab and temperature sensor and thin-film production facilities enhance JUMO’s expertise and offer our customers ultimate flexibility. JUMO is now one of the world’s leading manufacturers in this field.

Electromechanical temperature monitoring

JUMO’s decades of experience in manufacturing electromechanical thermostats and dial thermometers has made it a reliable partner. The ease with which our devices allow temperatures to be recorded and controlled without using auxiliary power has caused these devices to become standard in various industry sectors. The array of products ranges from mass-produced products to individual customer solutions in small-scale production.
