specific Embodiment approach 1

[0031] Specific implementation mode one: combine Figure 1 to Figure 5 Describe this embodiment, a standard device used for traceability of gelatin measuring instrument value in this embodiment, the standard device includes several gelatin measuring instrument transparency calibration blocks, each gelatin measuring instrument transparency calibration block includes shell 1, pressing sheet 2 , screws and transparency sheet 3;

[0032] The shell 1 is a cuboid, and the shell 1 is placed vertically along the length direction of the shell 1;

[0033] The front end surface of the housing 1 is processed with a No. 1 arched groove 4 with a bottom opening along the vertical direction, and the rear end surface of the housing 1 is processed with a light-through hole 5, and the No. 1 arch-shaped groove 4 and the light-through hole 5 are arranged corresponding to each other;

[0034] The pressing piece 2 is arched, and the middle part of the pressing piece 2 is processed with a No. 2 arch...

specific Embodiment approach 2

[0037] Specific implementation mode two: combination figure 1 Describe this embodiment, the outer dimensions of the pressing sheet 2 of this embodiment are set in conjunction with the outer dimensions of the No. 1 arch groove 4, the bottom of the shell 1, the bottom of the pressing sheet 2, and the bottom of the transparency sheet 3 are flush, and the transparency sheet 3 The external dimensions of the transparent sheet 3 are smaller than the external dimensions of the pressing sheet 2, and the external dimensions of the transparency sheet 3 are greater than the external dimensions of the No. 2 arch groove 6. Others are the same as the first embodiment.

specific Embodiment approach 3

[0038] Specific implementation mode three: combination figure 2 To describe this embodiment, the outer dimension of the light through hole 5 in this embodiment is smaller than the outer dimension of the first arched groove 4 . Such setting is to ensure that the transparency sheet 3 is arranged correspondingly to the light hole 5 , so that the light path on the gelatin measuring instrument just passes through the transparency sheet 3 when passing through the light hole 5 . Others are the same as those in Embodiment 1 or 2.

Abstract

The invention discloses a standard device for gelatin tester value traceability and a use method. The invention particularly relates to a calibration device, and aims to overcome the defects that in the prior art, a measurement calibration method for a gelatin tester and a corresponding measurement standard device for calibrating the performance of the gelatin tester are lacked, and the measured data of the gelatin tester cannot be traced. According to a product, a pressing piece screw hole is machined in the middle of the upper portion of a pressing piece and located over a second arch-shaped groove, the pressing piece is vertically placed in a first arch-shaped groove in the length direction of a shell, a transparency piece is placed between the pressing piece and the shell, and the pressing piece is screwed on the pressing piece screw hole and the shell through a screw to press the transparency piece. The method comprises the following steps: carrying out magnitude transfer assignment on the transparency of the transparency sheet as a standard value, adjusting the gelatin determinator, carrying out calibration measurement on the gelatin determinator, carrying out indication error calibration on the gelatin determinator, and carrying out measurement repeatability calibration on the gelatin determinator. The device and the method are used for calibrating the performance parameters of the gelatin tester.

Description

technical field [0001] The invention relates to the technical field of metering and calibration, in particular to a standard device for tracing the source of a gelatin measuring instrument and a method for using it. Background technique [0002] Gelatin is a macromolecular hydrophilic colloid with a relative molecular mass of about 50,000 to 100,000. Gelatin is the product of collagen denaturation. Gelatin is a colorless to light yellow solid, which can be divided into photographic gelatin, edible gelatin and industrial gelatin according to its performance and use. The raw materials for the production of gelatin are mainly animal skins, bones and leather industry waste. More than 60% of gelatin in the world is used in the food and confectionery industry. In frozen food and meat products, gelatin is used as a jelly agent, and gelatin is used in food coatings to make cakes and various icings. The unique properties of gelatin make it play an important role in traditional phot...
