One of the most prominent engineering values of HZLY-200A is the integration of four core operations at the transformer overhaul site into one device, significantly reducing the number of on-site equipment and coordination complexity.Implementation of four functions in oneFunction 1: Transformer oil
There are two main methods for measuring the internal resistance of batteries: direct current discharge method and alternating current injection method (ACIR). The HZNZ-100 adopts the AC injection method, which is not a random choice, but the only practical technical route under the key requirement
The HZMD-2001 utilizes the densitometer method, with the instrument providing a precise constant temperature environment, and the actual measurement of density being carried out using a petroleum densitometer. Many people have been using constant temperature bath densitometers for a long time, but t
When conducting low-temperature performance testing of oil products, pour point and freezing point are two indicators that often appear simultaneously and are easily confused. Many people in the laboratory told me that when they first started in the field, they couldn't figure out why sometimes
I have learned to operate the kinematic viscometer, but every time I see the instrument automatically calculate a result, I always feel like it's a black box. In fact, the calculation logic of the capillary method is very simple, and it is based on a classic fluid mechanics principle that has be
