A method for regulating a heater including at least one heating element having a temperature-dependent electrical resistance is disclosed. The method may include determining, with a regulating unit of the heater, a current heating behaviour of the heating element based on a time profile of the resistance of the heating element. The heating element may exhibit (i) an NTC heating behaviour at temperatures below a transition temperature, (ii) a PTC heating behaviour at temperatures above the transition temperature, and (iii) a transition between the NTC heating behaviour and the PTC heating behaviour at the transition temperature and a resistance minimum. The method may further include determining, with the regulating unit, at least one input parameter for the heating element based on the current heating behaviour. The method may also include regulating, with the regulating unit, the heating element via the at least one input parameter.

An electrochemical measurement cartridge includes a container including a first analysis chamber for receiving a fluid to be analyzed and a second calibration chamber for receiving a calibration fluid; an electrochemical measurement sensor including at least one work electrode and one reference electrode; a container supporting the sensor and a cover arranged mobile relative to one another to confer on the cartridge at least two separate operating configurations, a first configuration in which the sensor is communicating with the first analysis chamber and a second configuration in which the sensor is communicating with the second calibration chamber; sealing between the chambers of the container and the cover; and a drive member for providing a relative movement of the container relative to the cover.

A sleeve soldering device has a displacement sensor and a heat flux sensor. The displacement sensor detects a physical quantity related to a pressure from a heated sleeve heated by a heater onto an electric board when the heated sleeve presses the electric board. The displacement sensor detects a physical quantity related to a deformation amount of the electric board due to thermal energy from the heater. The heat flux sensor detects a physical quantity related to a heat transfer amount from the heater to the electric board when the heated sleeve is pressed to the electric board. A control part compares each of detection values obtained from the displacement sensor and the heat flux sensor with a respective judgment reference so as to detect whether each detection value satisfies the respective reference.
