OIML and ASTM StandardCast ironCast iron weights are a measuring tool that measures the weight of an object by comparing its mass. It is done by placing a weight on the balance pan while weighing the weight of another object. Cast iron weights usually have precise weight values because they are calibrated on a precision balance. When the balance weighs an object, the weight exerts a certain force on the balance, which in turn affects the balance point of the lever, thereby achieving accurate measurement of the mass of the object. ‌

Why Choose Our Laboratory Instruments?

Our core technical team possesses interdisciplinary capabilities in mechanical design, electronic engineering, and software algorithms, enabling us to provide customized development services including special weighing range customization (such as ultra-micro weighing at the 0.01mg level or large weighing ranges above 10kg), explosion-proof certification (ATEX/IECEx Zone 1/2), integration of specific communication protocols (Modbus RTU, Profinet, 4-20mA analog output), and multilingual localization of the human-machine interface.

At the project execution level, we employ a stage-gate management model. Customers can participate in multiple rounds of technical reviews before the design freeze, and the engineering development phase only begins after the functional specification is confirmed, effectively controlling project change risks and delivery uncertainty.

On the manufacturing side, the company boasts a 3,000-square-meter self-owned production line equipped with fully automated calibration and testing benches and aging test chambers. This allows for flexible switching between small-batch trial orders (5-50 units) and large-scale orders, with a minimum order quantity (MOQ) at the lowest level in the industry.

In terms of after-sales service, customized instruments enjoy the same 24-month warranty commitment as standard products, a 10-year spare parts inventory commitment for key components, and value-added services such as on-site installation and commissioning, operation training, and metrological calibration guidance, ensuring customers receive original manufacturer technical support throughout the entire instrument lifecycle.

Precision Analytical Balance
A high-precision electromagnetic force-compensation weighing system delivering 0.1mg readability with automatic internal calibration, designed for quantitative analysis in regulated pharmaceutical, chemical, and research laboratory environments.
Digital Viscometer
A rotational digital viscometer with broad measurement range (10–6,000,000 mPa·s), featuring optional Peltier temperature control and compliant with FDA 21 CFR Part 11 for electronic data integrity in quality control applications.
Moisture Analyzer
A halogen-heated rapid drying moisture analyzer achieving 0.001g reading precision, equipped with an intelligent endpoint detection algorithm that automatically terminates heating upon sample constant-weight confirmation, suitable for high-throughput QC testing across food, chemical, and pharmaceutical sectors.
Calibration Test Weights
OIML R 111-compliant precision test weights available in E1 through M1 accuracy classes, crafted from non-magnetic austenitic stainless steel with mirror-finish surface treatment, traceable to CIPM mutual recognition arrangements for metrological calibration applications.
Our customized services are underpinned by nearly 30 years of independent R&D and manufacturing experience in precision instruments, building a closed-loop capability encompassing the entire process from capturing customer needs, designing conceptual solutions, verifying functional prototypes, to large-scale mass production and delivery.
