laboratory balance FA2004

Analysis balance is a sensitive device, which will be affected by a series of physical variables such as airflow, static electricity, gravity acceleration, and temperature.

Analysis Scale FA2204B

Analysis of balance is a sensitive device, which will be affected by a series of physical variables such as airflow, static electricity, gravity acceleration, and temperature.The shell cannot completely prevent the impact of interference factors on them. But we can reduce their exposure in the air through closed devices as much as possible.

Analytical Balance FA2204B

As a precision measuring instrument, an analytical balance is often used to determine the quality of solids, granules, powder and liquids. It is suitable for quantitative chemistry analysis. With the help of magnetic recovery principle, the readability of analytical balance has reached 0.0001 g.

High-end 190-1100nm With English Software UV Spectrophotomer UV/IR Visible Spectrum For Solid, Thin Film, Glass or Acryl

The principle of platform type thin film solid state tester analysis is to use the selective absorption phenomenon of different wavelengths of light by substances to conduct qualitative and quantitative analysis of substances. By analyzing the absorption spectrum, the structure and chemical composition of substances can be determined. Using high-performance grating to obtain monochromatic light, the monochromatic light continuously passes through the sample in sequence, and the transmittance of the sample for each wavelength is measured to obtain the transmittance spectrum curve.This instrument operates based on the principle of relative measurement, that is, selecting a certain band of air reference and setting its transmittance (i.e. transmittance T) to 100%, while the transmittance of the tested sample is obtained relative to that reference. The change in transmittance (transmittance T) has a certain functional relationship with the concentration of the measured substance, and wi...

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.
