Temperature control

Precise temperature control at a low energy requirement

Description

One of the most important criteria for a top quality incubator shaker is precise temperature control with a low energy requirement. On top of that, to ensure reproducible cultivating results, even temperature distribution across the entire shaking tray is crucial.

Electronic, fully digital PID control incorporating a microprocessor, accurately maintains the desired temperature in Kuhner machines. The minimal energy consumption of the cooling system is regulated by an intelligent controller. True temperature distribution is achieved by using high grade foamed insulation. This complex method also ensures optimal air circulation inside the chamber.

Technical data

   
Temperature, minimum 10°C above ambient
Temperature with refrigeration 15°C below ambient, min. +5°C
Temperature, maximum 80°C
Temperature accuracy ± 0.3°C (37°C), distributed across the entire tray / XC-machines: ± 0.25°C (37°C)
Temperature indication ± 0.1°C, digital
Temperature control PID, digital
Temperature sensor Pt-100, class "A" (DIN IEC 751)
 
Tolerance = 0,15°C + 0,002 x |t|
 
Examples:
t : 37°C, Tolerance = ± 0.22 °C
t : 20°C, Tolerance = ± 0.19 °C

Calibration of temperature sensor

Calibration is quite simple and is carried out using
  • an interface and a PC with the installed Kuhner Insight software
  • a temperature measuring device with sensor and certificate e.g. “TCAL 44” available from Kuhner
