Zhejiang Zhuocheng Testing Technology Co., Ltd. Adopts HSIN685 Intelligent Digital Pressure Calibrator to Enhance On-Site Metrological Accuracy

Zhejiang Zhuocheng Testing Technology Co., Ltd. (Hereinafter referred to as"Zhejiang Zhuocheng Testing") has recently procured the HSIN685 Intelligent Digital Pressure Calibrator from Beijing Hengsheng Weiye Technology Co.ltd(Hereinafter referred to as"HSIN"). The advanced instrument will be deployed for on-site calibration, inspection, and maintenance of industrial pressure gauges, reinforcing Zhejiang Zhuocheng Testing's commitment to service excellence through state-of-the-art metrology.

HSIN specializes in the R&D, manufacturing, and service of precision measurement and test equipment, with its products widely used across electric power, chemical, metallurgical, pharmaceutical, and other industrial sectors. The HSIN685 model delivered to Zhejiang Zhuocheng Testing represents the flagship Portable Calibrator of HSIN's product line. Its combination of ultra-high accuracy, multi-function integration, and ease of portability made it the preferred solution for the client.

Core Advantages Tailored for Full-Range Industrial Calibration

Ultra-High Accuracy for Reliable Data
The HSIN685 achieves accuracy classes of 0.02% / 0.05% FS, enabling precise calibration of pressure transmitters, pressure gauges, pressure switches, sensors, and other pressure instruments. With a pressure range covering –0.1 to 250 MPa, the device supports calibration from micro-pressure to ultra-high-pressure scenarios, meeting the diverse on-site measurement demands of Zhejiang Zhuocheng Testing.

Multi-Function Integration – One Instrument, Multiple Applications
The calibrator integrates measurement functions for pressure, current, voltage, and temperature, and includes a built-in DC24V power output, making it capable of calibrating HART smart transmitters. It supports one‑key switching among 21 pressure units (MPa, kPa, PSI, etc.) and offers functions such as pressure leak testing, peak recording, data storage, and data export. A single device accomplishes multiple calibration steps, significantly improving operational efficiency.

Portable and Efficient for On‑Site Work
Weighing approximately 0.7 kg, the compact HSIN685 is powered by a large‑capacity lithium battery, supporting extended continuous operation and easy transport by technical personnel across different job sites. The 4‑inch capacitive touchscreen remains clearly readable under strong light. Features such as zero-reset and one‑key calibration simplify operation, lowering the skill barrier for fieldwork.

Robust and Durable – Hardware Reliability in Harsh Environments
Designed to withstand industrial conditions including vibration and temperature variations, the HSIN685 also provides RS232 and USB interfaces for communication with host computers, enabling software‑assisted calibration to meet enterprise quality management and regulatory compliance requirements.

This collaboration reflects Zhejiang Zhuocheng Testing Technology Co., Ltd.’s strong recognition of Hsinyo Weye’s product quality and technical expertise. It also marks a significant step for Hsinyo Weye in serving the industrial market across Northeast China. Going forward, both parties will deepen technical exchanges and operational coordination based on this cooperation. Hsinyo Weye remains committed to empowering more industrial enterprises with high-precision metrology equipment and professional services, enhancing measurement reliability, reducing maintenance costs, and supporting the high-quality development of the industrial automation sector.
