Product description
The sound fork counter, consisting of the forklift and amplifier parts, pressing two sets of voltage crystals at the root of the fork, which are used as a drive and the fork unit produces vibration; the other is used as a detector to convert the fork unit into a voltage signal. When the fork is blocked, the oscillator's amplitude becomes smaller and relays output switch signals。

2. Multiply pencil hard gauge models; zrx-12232
Product overview:
1. Based on gb/t5739-1996。
2. In the form of pencil markings, they are applied to the determination of the hardness of the coating。
3. Portable pencils, three specifications: 500g, 765g, 1,000g。
Structure and rationale:
The instrument is mechanical, with three points of exposure to the measured surface. The two dots, one dot, and one dot, the pen core, are always guaranteed to form a 45-degree cortex of the measured coating, and to drive the instrument movement at a high level, so that the test process can be completed and the ability of the coating to resist deformation measured。
Use requirements:
Gb1279-79 " general preparation of painting membranes " , which is prepared in three blocks, usually smoothing the pedal iron plate 120*50* (0. 2-0. 3) mm, or the base and size of the product as otherwise specified。
2. Test conditions: carried out in accordance with the conditions specified in the product standards or the construction requirements。
Methods of use:
Preparation: cut the pencils to the surface of the column lead core 5-6 mm with a sharpening knife (which cannot be loosed or cut), hold the core to the angle of 90° with the “no:400” sandpaper, and circle them continuously to rub the end of the pen, until a sharp lead core on the edge of the end is obtained (the edge shall not be broken or gaped) is rotated 180° after each time it is used, or is re-used after grinding。
2. Operation: the instrument is placed on a flat table, the pads are placed below the instrument, the sharpened pencil is inserted into the main hole of the instrument, the pencil is exposed to the table and the screws are strung。
3. Placing the instrument on a test plate, pressing (by this force size or to break the end of the lead core or to plough a plough) at approximately 1 mm per second. Starting with a hard pencil, there are five 3 mm long lines of pencil ploughs per class until a pencil without ploughing is found, the hardness of the pencil represents the hardness of the coated。
3. Wind / wind / wind / wind / mini wind / model: zrx-1217
Application:
(c) data collection in boilers, refrigeration, heating, ventilation, environmental monitoring, nautical surveys
And data collection for weather forecasting, field operations and fire departments。
