General calibration

• Importance of 'uncertainty' - Why it is important to pay attention to the uncertainty
• Influence on uncertainty - Elements of the "uncertainty circle"
• Calibration certificates - Accredited or traceable

Temperature calibration

• True temperature calibration
• Correct use of inserts
• Choose the correct insert

Dry-block calibrators

• Dry-block principle - The basic design of a temperature calibrator
• Dual-zone - (Active) as in JOFRA ATC series - Best possible temperature homogeneity in the block
• Dual-zone - (Central) as in JOFRA ITC series - Very good temperature homogeneity in the block
• Efficient cooling techniques

Deadweight testers

• Floating ball - Principle of the pneumatic deadweight testers
• Re-entrent piston/cylinder - Principle of the piston/cylinder in the hydraulic deadweight testers
• Overhung weight carriers - Hydraulic deadweight testers
• Dual volumen handpump - Principle of the hydraulic hand pump
