About the test gauges:

1. Lampcap and Lampholder Gauges are designed according to IEC60061-3, it is also called to go / no-go gauge.

2. The structure and sharp (thread-like waveform) of gauges for lampcap and lampholder are calculated and optimized by computer, and then processed by computer machine to reach high precision and appearance.

3. The lampcap and lampholder gauges (go / no-go gauge) is made by hard alloy, and handled with QPQ composite infiltration which greatly improved the abilities of rust prevention and wear resistance, the rockwell hardness can reach HR58⁰ above, the service life is more than 3-5 times longer than ordinary gauges.

4. The Lampcap and Lampholder gauges can pass the calibration of the third-party institutes, and get the calibration certificate.
