Company profile
Hwa Chih Technology Co., Ltd. was established in 1999 and manufactures pressure gauges, differential pressure gauges, and thermometers. Its factory is located in Bade District, Taoyuan City, and its departments include administrative, research and development, production, business, and other units. The company states that all of its products are made in Taiwan. Its operating tenets are quality, technology, service, and innovation, and the company describes continued development and innovation under those four tenets. Hwa Chih states that it has more than 100 patents and certifications worldwide and sells its SAFE brand internationally. Since 2010, the company has developed and manufactured products for automation and preparation for Industry 4.0. It identifies digital pressure gauges and differential-pressure series among the products created through that development work and states that these products have been adopted by major electronics manufacturers and traditional industries at home and abroad. The company describes this development path as a transformation into a digital-instrument manufacturer while continuing to improve product quality and implement after-sales service. Its listed product lines include semiconductor pressure gauges, digital pressure gauges, machine pressure gauges, micro differential pressure gauges, PP diaphragm pressure gauges, mechanical pressure switches, pressure transmitters, and thermometers. A separate company description also identifies J-5000 Aero Type Differential Pressure Gauges.
Exhibits
The Ultra High Purity Pressure Gauge offering includes SAFE-E / 40. 50. 60 Series at EP Level, described as SAFE-E Series Electro-Polishing Grade, and SAFE-B / 40. 50. 60 Series at BA Level, described as SAFE-B Series Bright Annealing Grade. SAFE Series pressure gauges are designed for high-purity gas systems used in semiconductor, electronics, medical, biotechnology, and pharmaceutical industries. Case outer-diameter options are 40mm, 50mm, and 60mm, with Low mount and Center Back mount styles. Connection options include 1/4" NPT, 1/4" Metal Face Seal Fittings (Male/Female) in All Swivel Type, and 1/4" TUBE WELDING. Specified materials include a SUS316L Bourdon with BA or EP surface treatment, a SUS304 casing, stainless-steel movement, polycarbonate (PC) cover, white aluminium plate, and black aluminum-alloy point. Accuracy is listed as Grade A ±1.0% F.S for 50mm and 63mm dial sizes and Grade B ±2.0% F.S for 35mm, 50mm, and 63mm dial sizes. The listed ambient-temperature range is -40℃ to +65℃, maximum fluid temperature is +100℃, and He leakage rate is less than 1.0x10⁻¹⁰ Pa・m³/sec. For SAFE-E/SAFE-B cleaning, manufacturing, and inspection, cleanliness is listed as ASME B40.100 Cleanliness LEVEL 4, with ultrasonic cleaning. Assembly is performed at CLASS 10,000 C.R, adjustment and correction at CLASS 100 C.R, and leak testing uses Helium. The product specifies no oil and water treatment and uses polyethylene material with vacuum double-layer packaging. The pressure-range list spans multiple positive-pressure and compound ranges, including values from 0-30psi/K through 0-6000psi/K and compound entries from -30inHg-15psi/K through -30inHg-1000psi/K. Together with semiconductor pressure gauges, the broader lineup includes digital pressure gauges, machine pressure gauges, micro differential pressure gauges, PP diaphragm pressure gauges, mechanical pressure switches, pressure transmitters, thermometers, and J-5000 Aero Type Differential Pressure Gauges.
