What Clube Literário does

East Tester (operating as 奇异果·奇异果（中国）官方网 under the parent entity 中创电子 / Zhongchuang Electronics) is a Hangzhou, China-based manufacturer of electronic testing and calibration instruments sold under the proprietary East Tester (ET) brand. Founded in 1998, the company built its initial business around thermal process calibration instruments — portable signal calibrators, multi-channel signal generators, portable and desktop pressure calibrators, and temperature calibration devices — before expanding in 2011 into electronic measurement instruments including high-precision digital multimeters (4.5 to 6.5 digit), function/arbitrary waveform generators, LCR digital bridges, programmable DC power supplies, electronic loads, digital storage oscilloscopes, and multi-channel temperature scanners.

The underlying technology rests on direct digital synthesis (DDS), automatic balance bridge principles, and SCPI-based remote control, with product-level accuracy benchmarks such as 0.05% basic LCR accuracy, 13-bit vertical resolution at 200MSa/s sampling in waveform generators, and pressure ranges from -100kPa to 60MPa. The portfolio also includes automation-oriented software systems (ET3100 secondary instrument verification, ET3900 thermocouple/RTD verification, ET-ZY200 pressure verification management), positioning the company beyond point-instrument sales into integrated calibration workflow software.

The business model is direct B2B hardware sales to industrial customers in electric power, petroleum, chemical, metallurgy, metrology, railway, textile, environmental protection, electronics, and energy sectors, supplemented by higher education and electronics manufacturing buyers. Pricing is quote-based via phone (0571-56770266) and QQ customer service, with products sold as one-time hardware purchases bundled with technical support and after-sales service. The company employs 120+ staff including 30+ R&D engineers, holds 11 software copyrights and 9 nationally/provincially certified product achievements, and operates an ISO9001:2008-certified 7,300 sqm factory in Hangzhou North Software Park.
