Micro calibration baths OBM/OBM-LT - Kambič

The Kambič OBM and OBM-LT micro calibration baths are portable fluid calibration baths for temperature sensors, probes and instruments. The range includes two models: OBM, for +35 °C to +220 °C, and OBM-LT, for -35 °C to +130 °C. Fluid calibration provides efficient heat transfer, while the vertical flow design contributes to thermal stability and uniformity at mK level.

Advantages 
  • Enables sensors to be calibrated directly in fluid, with efficient thermal transfer between the bath and the device under calibration;
  • Thermal stability and uniformity support tests and calibrations with higher operational repeatability;
  • Portable format, suitable for laboratory calibration, technical bench use, or field interventions;
  • The 7” touchscreen controller and OB-Tool software reduce dependence on continuous local operation and facilitate data collection;
  • The construction with AISI 304 stainless steel wetted parts supports durability and cleanability in laboratory or industrial use;
  • The two temperature ranges cover low-temperature applications and higher positive temperature applications, depending on the selected model.
 
Applications
  • Chemical, process, energy, water and environmental sectors, for verification of temperature instrumentation;
  • Food and beverage industry, in processes where temperature measurement is critical;
  • Metrology and calibration laboratories;
  • Pharmaceutical industry, biotechnology and regulated laboratories, where compatible temperature sensors need to be calibrated;
  • Quality, validation and industrial maintenance departments;
  • Research, development and testing of sensors or thermal systems.
