Product Description

Product Performance Introduction

ultra‑micro balances are designed for weighing tiny‑mass samples. Equipped with a proprietary monolithic electromagnetic sensor machined from a single block of high‑purity aluminum alloy through high‑precision integrated cutting. This design eliminates hundreds of discrete components found in conventional sensors and delivers superior structural integrity and durability. Consistent material properties make the sensor less susceptible to temperature fluctuations and greatly improve stability. Precision machining provides outstanding resolution and fast response. Featuring automatic calibration: built‑in weight calibration triggered by temperature drift or time interval. Color touch‑screen UI with Chinese language delivers safe, simple and intuitive operation.

Application Scope

Suitable for laboratory quality control, chemical laboratories, particulate‑matter weighing and stand‑mount weighing applications.

Key Modules	Description
Monolithic Sensor	The proprietary high‑performance monolithic sensor is the core weighing component, directly determining weighing speed, accuracy and stability. It enables the XE‑series to meet strict laboratory requirements for precision, accuracy and repeatability.
Display Unit	Large‑format full‑touch screen delivers clean, intuitive user interface for easy operation and clear visual feedback.
Internal Calibration (IsoCAL)	Built‑in IsoCAL automatic internal calibration function ensures reliable weighing results. Fully‑automatic calibration triggered by temperature change & time interval.
Application Programs	Pre‑loaded with 12 built‑in application routines, supporting print output and data export compliant with GLP / GMP requirements.
Communication Interfaces	Auto‑recognition for D&T printers & secondary displays. RS‑232 and USB‑C interfaces allow direct PC connection, data export to Excel, data storage & retrieval.
Level Adjustment (Optional)	Motor‑driven automatic levelling function for fast and convenient horizontal calibration.

Additional features

• Unique split‑body mechanical layout
• Optimized appearance & material quality
• Standard static‑elimination device supplied
• Optimized micro‑sample weighing function
