digital display meter

ES-8A adopts three-stage interference filtering design, which attenuates and filters the interference signal input from the electronic ruler signal line in a very wide frequency spectrum (1KHz-1000MHz), so that ES-8A achieves the highest level of anti-interference ability * Strict and careful component layout and PCB wiring to achieve the best ground crossing design, so that ES-8A has excellent performance in anti-interference ability and electromagnetic compatibility (EMC). ES-8A adopts linear power supply and advanced interference filtering circuit, which greatly improves the anti-interference ability of power supply.
Adapt to poor power supply 
Based on Easson's many years of experience in electronic ruler digital display system design, ES-8A digital display system continues to use the proven successful concept of low power consumption system design, so that ES-8A can use a strict * stable and reliable, high voltage shock resistance * strong, anti-interference ability of linear power supply system, in addition, ES-8A adopts a pressure-sensitive capacitor combination filter circuit to further enhance the anti-interference ability and high voltage shock resistance.
* High quality and durable keypad 
ES-8's key panel uses membrane switch industry consensus * high quality, * expensive British AUTOTYPE company AUTOTEX series polyester (POLYESTER) key membrane.
AUTOTEX key film features toughness and durability, compared with the usual use of polycarbonate (POLYCARBONATE, or PC) key film with higher scratch resistance, higher acid and alkali resistance and industrial solvent capacity, switch key life more than 100,000 times.
Rugged aluminum alloy housing 
ES-8A's front plate is made of 1.5mm thick electrolytic rust-proof iron plate, the front and rear shells are made of pressure injected aluminum alloy, and the paint adopts advanced electrostatic spraying layer to ensure high surface hardness, not easy to scratch, durability and long-term freshness.
ultra-low temperature transformer 
ES-8A adopts power transformer conforming to European CE safety standard structure and Nippon Steel with magnetic permeability up to 18,000 Gauss
Corp.'s Z11 series silicon copper sheets are used as magnet cores for transformers. The temperature rise of the transformer during operation is reduced to only about 5 degrees Celsius, which is safe and reliable and effectively prolongs the working life of ES-8.
