Thông số kỹ thuật

Stationary temperature calibration bath

Model LR- Cal BK40-M

Range -40 ° C. .. +125 ° C

 

The portable temperature calibration bath LR- Cal BK40-M serves as a resource and reference temperature in one unit, for testing and calibration of temperature measuring instruments of all kinds, it is particularly well suited for laboratory and glass thermometer.

It is characterized by a particularly robust construction with stainless steel liquid tank, and modern microprocessor controller.

The large usable volume of about 10 liters ensures high temperature stability over the entire range, characterized gleichzeitigke a calibration of multiple samples is possible. The heating vessel is filled with a suitable calibration which is supported by means of a vertical stirrer continuously in a homogeneous state. The agitator is driven by an electric motor 80W. The units are also equipped with a safety, an overflow and a valve for emptying the hot box.

Optionally, the temperature calibration bath can LR- Cal BK40-M are provided with a vertical overflow system to further improve the temperature stability and uniformity.

The thermostatic temperature calibration bath LR- Cal BK40-M is used

  • Testing and calibration of temperature sensors
  • Testing and calibrating glass thermometers
  • Testing and calibration of temperature measuring chains
  • Checking and adjustment of thermostats and thermostatic valves
