Aczet Digital ABBE Refractometer (ARM-2S) – Semi-Automatic Precision for Demanding Laboratory Applications
Bridging Optical Precision with Digital Convenience
For laboratories that refuse to compromise between traditional optical accuracy and modern digital efficiency, the Aczet ARM-2S Digital ABBE Refractometer delivers the perfect synergy. This semi-automatic workhorse combines German optical heritage with Japanese sensor technology, offering pharmaceutical labs, petroleum refineries, and food quality centers a robust solution for refractive index (nD) and Brix analysis with unparalleled repeatability.
Engineered for Critical Measurements
1.) Dual-Measurement Excellence
| Parameter | Specification | Industry Impact |
|---|---|---|
| Refractive Index | 1.3000–1.7000 nD (±0.0002) | Essential for oil purity verification |
| Brix Range | 0–95% (±0.1%) | Critical in sugar concentration control |
| Temp Compensation | 15–45°C (0.1°C resolution) | Ensures accuracy in tropical environments |
2.) Semi-Automatic Operation
- Optical Alignment: Manual fine-tuning via dispersion-corrected telescope
- Digital Readout: Instant LCD display of nD/Brix/temperature
- One-Touch Calibration: Auto-zero with NIST-traceable standards
3.) Industrial-Grade Durability
- Hard Glass Prism: Resists scratches from abrasive samples
- Stabilized Light Source: Consistent illumination (6.3V/0.25A halogen)
- All-Metal Housing: Withstands daily lab abuse
