NEWS & EVENTS
How to use the electric density gauge?
06-16
The electric density gauge strictly enforces national standards and is an instrument for measuring the density and compaction of hot mix asphalt pavement. Electric density gauge adopts electromagnetic induction technology instead of nuclear source radiation method, low cost, high safety, users do not have to worry about the cumbersome EIA application, time-consuming training, and harsh transportation control. With simple calibration, high accuracy, repeatability, and touch screen operation, the electric density gauge allows users to complete relevant operational training and master the techniques of on-site quality inspection in a short period. The electric density gauge can quickly measure the road separation, low density, uneven areas. Next is an introduction to the use and precautions of the Densitometer.
Retroreflectometer for road marking in rainy days
06-21
Retroreflectometer for road marking plays a very big role in our traffic inspection, because many road markings and so on have a very big impact on the traffic, so it is necessary to use the measuring device to inspect the road markings during rainy days. Here we will look at the different features of the retroreflectometer for road marking used on rainy days and the introduction of moisture-proof methods.
Universal testing machine sensor installation of attention
06-23
As an indispensable part of the universal testing machine, the role of the sensor, I believe I do not need to say, we all know the first, it is a kind of physical quantities, chemical quantities, and other information that can be felt by certain rules into a device to facilitate the measurement and transmission of signals, therefore, for the installation of the sensor, we need to pay special attention to the following matters.
Universal testing machine shutdown causes
06-28
We use the universal testing machine in the process, there may be a sudden shutdown of the equipment, when encountering this situation, the user should learn to analyze the causes of the failure, and according to the specific reasons to seek solutions. Today I will briefly analyze the causes of the machine's downtime and the corresponding solutions, including the introduction of maintenance and repair methods.
