Calibration of Electronic Digital Balance, with issue of F-Gas compliant certification
The price of the calibration service already includes the cost of shipping the certified instrument from the laboratory to the customer's premises, by DHL courier (including islands).

Digital electronic balance calibration procedure:
Normative Ref. - EURAMET cg-18.
A preloading cycle is carried out on the instrument being calibrated: this consists in applying in sequence on the balance pan two increasing loads corresponding to half and maximum of its measuring range three times. Before starting the measurements, reset the balance. The sample weights must be applied in ascending and then descending sequence between the minimum and maximum values of the calibration range, always placing the load in the centre of the balance pan. In the ascending sequence, the weights should be added to the previous load without removing the load completely. In the decreasing sequence, weights must be removed from the previous load without completely removing the load. The calibration report, completed in English and Italian, should contain the following data: - Nominal values of the measuring points (9 points distributed in the Range and communicated by the customer) - Measured values for 5 cycles - Deviation from the nominal value - Eccentricity error check - Relative measurement uncertainty of each point detected (Estimated standard uncertainty 0,005 kg.
Important: an identification label will be applied to each calibrated and certified instrument, showing the number of the calibration report and the serial number of the instrument; the label will also include a date stamp showing the calibration deadline (to be paid by the customer). An additional label with a QR CODE will also be applied to the instrument, making the calibration report immediately available on a smartphone (very useful for the refrigeration technician who is working on site and needs to demonstrate the conformity of the instrument in real time).
How to purchase the calibration service:
For the costs of the calibration service, refer to the official GeneralGas price list (separate code for each type of calibration).
1. The customer orders the service at the conditions indicated in the official GeneralGas price list (the price of the calibration service is already inclusive of the cost of shipping the certified instrument from the laboratory to the customer's premises).
2. The customer sends the instrument to be calibrated and certified directly to the QuickCheck laboratory, at the following address (to be indicated on the delivery note): GeneralGas c/o QuickCheck s.r.l. Via Aretina, 25, 50065 Loc. Sieci (FI) Telephone: 055 83638 e-mail address: stefano.boscaro@quickcheck.it
3. Once the calibration has been carried out, the instrument, together with its calibration certificate, will be sent directly to the customer, by DHL express courier (carriage paid).
IMPORTANT NOTE: Calibration consists of checking the instrument and issuing a calibration certificate, in accordance with the requirements of EU F-Gas Regulation No. 517/2014.
If, during the analysis phase, the instrument subject to the calibration report is found to be outside the acceptable limits, it is necessary to proceed with calibration.
Calibration, i.e. error correction, is not always feasible and is a service (with relative extra cost) supplied separately, because it actually constitutes a repair of the instrument.
In other words, the calibration/certification does not correct the error of the instrument, but is rather a snapshot of the state of the instrument itself; in the calibration service, only a zero correction is permitted (and, if this is necessary, it is obviously possible to carry it out, directly during the calibration phase).
