The CP0501 set includes an E2 reference weight with a mass of 20 g with which the force sensor of your tensiometer can be reliably adjusted. The actual value for the mass measured by the force sensor is adjusted to the nominal value of the accurate reference weight. The attached certificate from the German Calibration Service (DKD) indicates the high level of precision of the weight. The set also includes a hook and force sensor adapter to facilitate easy attachment of the weight and a pair of tweezers to ensure the weight can be attached without soiling. A high-quality case is provided for safe storage of the set.
