Labtron Digital Refractometer offers a wide measurement range for refractive index and brix percentage with accuracy. Their automatic temperature correction feature guarantees accuracy even in fluctuating environments. They have a rugged glass prism that ensures durability and reliability. Our Digital Refractometer comes with a high-definition LCD display, ensuring crystal-clear visibility of results.


Labtron’s digital refractometer LDRF-A14 incorporates automated temperature compensation powered by an internal sensor that continuously monitors sample temperature. Through integrated algorithms, the instrument dynamically adjusts refractive index readings to standard reference temperatures, effectively correcting thermal fluctuations. This precision reduces errors caused by environmental changes, delivering reliable results whether you're in a hot processing plant or a cold storage lab. With accuracy and resolution of 0.0001?nD, this compensatory control is crucial for maintaining consistency in critical analyses. The robust design also includes a rugged glass prism that maintains thermal stability. Together with a back-lit LCD display, you get clear readings even during temperature adjustments. Consequently, the LDRF A14 is well-suited for sectors ranging from food and beverage to pharmaceutical R&D.
Labtron’s Digital Refractometer LDRF-A14 is built for efficiency: it offers rapid stabilization and readout, enabling dozens of measurements per hour with minimal downtime. Its high-definition LCD display and intuitive UI enable quick sample entry, immediate visualization of results, and easy navigation through functions. The unit’s auto-correction mode ensures consistent output across sessions, while its built-in printer interface and data export capabilities streamline record-keeping. A tough prism design minimizes maintenance, even in high-use environments. Its compact benchtop footprint beautifully matches busy labs and production lines. From clinical research to quality control in confectionery or petrochemical industries, the LDRF A14 delivers consistency and speed
Labtron’s digital refractometer LDRF-A14 offers a versatile measurement range of nD1.3000 to 1.7000 and Brix?0–95%, allowing quantification of transparent or translucent solids, liquids, and sugar solutions. Its precision makes it ideal for diverse applications—like measuring sugar in juices, refractive index in solvents, or concentration in pharmaceutical formulations. The device is engineered to analyze both clarified and slightly turbid samples thanks to its advanced optical system. Industries such as food and beverage, oils & petroleum, clinical labs, and flavour & fragrance manufacturing commonly deploy it for seamless, accurate readings. From lab research to industrial quality oversight, consistently meets strict analytical requirements.
Labtron digital refractometer LDRF A14 is equipped with built-in memory capable of storing thousands of readings-no external drives needed. It features USB, RS 232, and optional Bluetooth or Ethernet interfaces, making data transfer seamless to printers, PCs, or LIMS systems. Users can export results in Excel, PDF, or CSV formats for audit compliance and quality traceability. A built-in timestamp and user ID tagging, compliant with 21?CFR Part?11 standards, provides secure record-keeping in regulated environments. The intuitive menu enables batch export and selective recall of stored measurements. An automatic log of calibration history is maintained for effortless audit readiness. This robust functionality supports demanding R&D, production, and QA workflows.
Labtron’s digital refractometer LDRF-A14 integrates a high-performance optical prism made of tough sapphire that resists corrosion and scratches, simplifying cleaning after each measurement. Its photoelectric sensor and CCD detection system accurately reads the critical-angle boundary, even through small air bubbles or slight turbidity. The prism's hydrophobic coating helps prevent sample sticking and ensures full coverage—even with viscous fluids. An auto-clean mode gently back-flushes the prism to clear residues, reducing downtime. The unit’s sample volume requirement is minimal, allowing quick transitions between different sample types. Combined with fast stabilization routines, it delivers consistent, repeatable results in industries such as food, pharma, and chemicals.
