TM8000flex – Detailinformationen


In blood gas systems, samples are measured at 37°C. For deviating patient temperatures, it is possible to calculate a temperature corrected result. For these correction values, calculation models are usually used which do not take all influencing variables into account. Therefore significant deviations in the calculated values are possible.

With the TM8000flex, samples from 20°C to 39.9°C can be tonometered and for sample temperatures, deviating from 37°C, the true values can be achieved. Thus, for certain applications, specific offsets or temperature corrections can be determined, independent of the blood gas system used.

The innovative heating and cooling system used in the TM8000flex guarantees fast and precise setting of the desired target temperature, the robust design and the high-quality workmanship guarantee high reliability.

Product – Features


Wide Temperature Range

  • The wide temperature range from 20,0°C (even less) to 39,9°C – adjustable in 0,1° increments allows sample temperatures to be set over the entire diagnostic relevant range
  • The lower tmperature limit depends on ther relative humidity (dew point), condensation on the Tonometer Surface must be avoided


Innovative Temperature Management

  • The innovative and powerfull heating and cooling system ensures a rapid Setting of the selected target temperature  – after less than 30 minutes (starting from room temperature), the preselected temperature in the range from 20°C bis 39,9°C is reached with an accuracy of ± 0,1°


Compact and robust design

  • The compact design, high-quality components and ingenious temperature management ensure maximum operational reliability and longevity.


Features known from the TM8000 …

  • Simple operation – maintenance – disinfection
  • Safe sample handling
  • Fast equilibration – through thin film technology & rotation control
  • Reliable quality control of blood gas systems

The invalidy of Blood Gas Parameters from patients beyond temperature of 37°C


As a study of the UKR University Hospital Regensburg shows, serious deviations between the calculated temperature corrected values and the real measured values can occur at low sample- / patient temperatures..
