Product description
Transmission Line Parameter Test System is of an integrated structure, with a built-in variable frequency power supply module and a variable frequency voltage regulating output power supply. The frequency can be changed to 45Hz and 55Hz. Digital filtering technology is adopted to avoid the interference of power frequency electric field to the test and fundamentally solve the difficult problem of accurate measurement under strong electric field interference. At the same time, it is applicable to the occasions where the generator is used for power supply detection after all power outages.

Product Features The purity of the product, calcium and phosphorus ratio appropriate to ensure a higher degree of its biological effects. Phosphorus content greater than 21% of the products, their biological effects better. This unique high-tech companies use technology to make our products crystallization, high purity. Drying process advanced products, products with low free water under the premise that the product does not lose crystallization of water, avoid the product in the drying process for the loss of water caused by crystallization of biological effects of the reduction. coarse particles MDCP in the animals stay in the stomach longer and more conducive to the absorption of calcium phosphate, the product produced by micro-particles MDCP form, without any chemical binder.
