Product Features & Advantages

High-Precision Sensing Technology (Core Advantage): The ST2258C DJ Advanced Powder Resistivity Device uses imported piezoresistive sensors with ±0.5% accuracy—outperforming competitors (±1.0% average) in resistivity and bulk density measurement. This ensures data consistency for critical quality control and R&D projects.
User-Friendly Intuitive Design: No specialized training required—clear LCD interface with one-touch measurement, automatic data calculation, and storage (up to 10,000 sets of data). Simplifies operation for both experienced technicians and new users, reducing training costs.
Broad Material Compatibility: Compatible with fine powders (particle size ≤100μm), granules, and particulate substances (e.g., pharmaceutical excipients, chemical catalysts, metal powders, electronic ceramic powders). Eliminates the need for multiple instruments for different materials.
Durable & Long-Lasting Construction: 316L stainless steel measurement cell resists corrosion from acidic/alkaline powders; robust ABS casing with anti-drop design ensures 5+ years of continuous use (vs. 2-3 years for standard testers). Low maintenance requirements reduce downtime.
Dual Measurement Capability: Simultaneously measures bulk density and electrical resistivity in one cycle (≤60 seconds per sample), cutting analysis time by 50% compared to single-function devices. Improves lab efficiency and throughput.
Compliant with Industry Standards: Adheres to ASTM D4496 (resistivity) and ISO 60 (bulk density) standards, ensuring data validity for regulatory submissions (e.g., pharmaceutical FDA filings).

How to Use & Maintain

Pre-Use Calibration: Power on the device and warm up for 15 minutes. Perform calibration with the NIST-traceable reference powder provided (follow on-screen prompts) to ensure accuracy.
Sample Preparation: Collect a representative powder sample (≥60 cm3 to avoid sampling bias); remove lumps or foreign particles using a 200-mesh sieve.
Sample Loading: Pour the prepared sample into the measurement cell evenly (avoid air bubbles) and level the surface with the built-in scraper. Secure the cell cover tightly.
Initiate Measurement: Select "Bulk Density + Resistivity" mode on the LCD screen and press "Start". The device will automatically measure, calculate, and display results within 60 seconds.
Data Export & Storage: Save results to the internal memory or export to a computer via USB/RS232 for report generation and data archiving.
Post-Use Cleaning: Disassemble the measurement cell, clean with distilled water (or ethanol for organic powders), and dry thoroughly. Avoid abrasive cleaners to protect the sensor.
Routine Maintenance: Check sensor integrity monthly; replace O-rings annually (included in maintenance kit); store in a dry, dust-free environment when not in use.

Application Scenarios

Pharmaceutical Industry: Analyze bulk density and resistivity of active pharmaceutical ingredients (APIs) and excipients to ensure uniform drug formulation, flowability, and tablet compression quality. Critical for FDA/EMA compliance.
Chemical Manufacturing: Monitor raw material consistency (e.g., catalyst powders, pigment powders) to optimize production processes, reduce waste, and maintain product quality stability.
Powder Metallurgy: Characterize metal powder properties (e.g., copper, aluminum, titanium powders) to ensure consistent sintering performance and final product mechanical strength.
Electronic Materials: Evaluate resistivity of conductive/insulative powders used in circuit boards, coatings, and battery materials—ensuring electrical performance meets design specifications.
Academic & Industrial R&D: Study powder behavior under different environmental conditions (temperature, humidity) to develop new materials and improve existing formulations.
Quality Control Laboratories: Conduct batch-to-batch testing of powdered materials for industrial manufacturers, ensuring compliance with internal and international quality standards.
