Low Price High Voltage Digital Partial Discharge Tester

I. Product Information:


Product Description:
HZJF-124 digital partial discharge detector is the newly development digital LCD partial discharge detector for solving the problem of low brightness and short service life of the traditional local discharge detector. It is wildly used in measurement of partial discharge of various HV electrical products such as transformer, mutual inductor, HV switch, switch cabinet, zinc oxide surge arrester, power cable etc.

Product  Features:
1.After digital processing,the partial discharge signal is displayed by liquid crystal.
2.Easy operation
3.With multiple display mode like ellipse,line,or sinusoidal.
4.Adopt digital windowing technique to avoid influence of interference to measurement.
5.Arbitrary phase windowing,with selection of single window and double window,ellipse rotating 150 degree.
6.The current discharge map can be stored,static observation and analysis to partial discharge pulse.
7.Can store the current discharge map.

Martial Arts Mat

Martial Arts Mat is an EVA Mat, in double colors for reversible, in 100cm x 100cm, offering 2cm, 2.5cm, 3cm and 4cm thickness.

EVA martial arts mat is made from Eco-friendly, high density, closed cell, non-smell and non-toxic EVA foam material. With interlocking edges, each mat can be connected easily without any loose.

It is always used as EVA Tatami Mat, EVA Jigsaw Mat, EVA Taekwondo Mat, EVA Karate Mat, EVA Judo Mat, EVA Jiu Jitsu Mat and EVA Aikido Mat. The thick foam provides a protection for trainers when they fall on the floor. Also we have 3 different textures for surface of the mats, which is "T" texture, five strips texture and tatami texture. All of them provide a good traction to the feet.

The colors we usually offer for the martial arts mat is blue & red, blue & yellow, black & red, single black. Or we can offer customized colors based on customers` requirement.

We used heard many of customers complained about the bad experience on the bad smell mats they purchased from other supplier. Indeed, that may cost a lower even half of our price, it is because the EVA foam material is what we call second-hand material, its smell will make people uncomfortable. Melors promise that the EVA foam material we use would be never second-hand foam material, what we offer is truly non-smell and non-toxic.
