MODERNER GZY-2 drying time Recorder is an upgraded version of the GZY-1 model, which has a longer Timer Setting, between 3 and 48 hours. The GZY-2 drying time Recorder uses a stylus to draw across the coating at a constant speed and slowly, and observes the scratch tracks formed on the surface of the coating to evaluate the drying time of the coating. GZY-2 drying time Recorder has six styli, which can test six different products at the same time, saving cost and time, and high efficiency.
1. GZY-2 is driven by a stepping motor to provide accurate movement control.
2. There are six scribing needles installed on the carriage, and the movement of the carriage drives the scribing needles to move on the glass sheet coated with wet film.
3. The GZY-2 drying time Recorder will stop automatically when the journey ends.
4. Lift up the pressure plate on the lower part of the rear side of the carriage to manually move and reset.
5. The front end of the GZY-2 drying time Recorder is equipped with a ruler, which can convert the moving distance and moving time.
6. It has a timer of 3~48 hours and has five different moving speeds to choose from .




1. Preparatory work before the test:
(1) The test should be carried out under constant temperature and humidity conditions.
(2) The GZY-2 drying time Recorder should be placed on a flat table away from strong magnetic fields and strong electromagnetic pulse interference.
2. Operation method:
(1) Turn on the power and turn on the power switch at the back of the GZY-2 Drying Time Recorder.
(2) If the carriage is not at the starting position on the left side, lift the pressure plate at the lower rear side of the carriage, and manually move the carriage to reset.
(3) Install a suitable scribing needle (ball head or pointed head) on the scribing needle clip to keep the scribing needle rod perpendicular to the glass sheet.
(4) Loosen the set screw on the bracket, remove the glass piece, and prepare a wet film on the glass piece (the wet film should meet the relevant standards or meet the requirements agreed by the buyer and seller).
(5) Put the glass piece back on the bracket, and properly tighten the set screw at one end.
(6) Put down the stylus clip so that the stylus is in contact with the new coating layer.
(7) Select the appropriate speed gear, press the corresponding button, and the carriage starts to move slowly to the right. If you need to change the selection at this time, you need to press the stop button to re-select. After the specified time, the GZY-2 drying time Recorder will automatically stop and give a beeping sound.
(8) Corresponding to each drying stage of the observed trajectory, evaluate the results. The drying time can be obtained by converting the scale on the edge of the GZY-2 drying time Recorder.

Explanation: As shown in the picture, the coating film starts to dry after 2 hours of the test (at the beginning of track ③); it has been hard-dried at 5 hours (at the beginning of track ⑤, the track disappears and the product disappears).
1) After using for a period of time, the screw rod and slide rod in the GZY-2 drying time Recorder should be properly lubricated from the openings on both sides.
GZY-Film Applicator: wet film thickness 38μ/76μ; or wet film thickness 75μ/150μ; (wet film thickness can also be customized according to customer requirements).
GZY-coating accessories: suitable for 3×23×340 glass sheets.
