Hysteresis Loop Tracer
MESA
The MESA is the only hysteresis loop tracer on the market that can make measurements in the frequency range of 10 Hz and below. Competing units operate with more-easily generated 60 Hz drive fields, and can have errors of as much as 30% in coercivity (Hc) measurements.

Material Science Laboratory Instruments
our material science laboratory instruments basically consists of four instruments first, young modulus apparatus which is used for determining the young modulus elasticity of a wire by stretching it. Then second is curie temperature kit which is used for determining the Curie Temperature. With the determination of dielectric constant of PZT material with Temperature variation. After that comes dielectric constant kit which is used for measuring the dielectric constant of solids and lastly our universal B-H Curve Tracer which is used for tracing the B-H loop which is very difficult and needs a good machinery for doing so.

Active Dual Loop Antenna
KH30936
Beijing KeHuan Century EMC Technology Co,.LTD
KH30936 active dual loop antenna is used for adjusting, testing, measuring and other receivers. It has many advantages:1. The antenna coverage frequency is wide: 150KHz ~ 30MHz .2. The field strength value is measured according to the correction coefficient within the effective frequency range, which is convenient to use.3. The antenna power is supplied by the host, which is convenient for outdoor measurement.4. Compared with the single loop antenna, the advantage is to read the maximum value directly, which eliminates the tedious steps of rotating the antenna to find the maximum value and the interference of the human body to the signal.
