The Techtom LH 3.7 Auto Digital Refractometer is a fully automatic laboratory refractometer designed for fast and convenient measurement of refractive index and Brix values. Its touchscreen display and automatic measuring system make routine sample testing simple and efficient, making it a practical choice for laboratories, quality-control departments, food industries, pharmaceutical laboratories and research environments.

The instrument measures refractive index (nD) from 1.30000 to 1.70000 and Brix from 0 to 100%, providing a broad measurement range for a variety of liquid samples and sugar solutions. The touchscreen interface provides direct access to measurement information and simplifies day-to-day operation.

The LH 3.7 also displays the sample temperature, with a temperature display range of 0–50°C. Its internal memory can store up to 1,024 measurement results, allowing users to retain previous readings for convenient reference and laboratory record keeping.

Applications

The Techtom LH 3.7 is suitable for food and beverage testing, sugar and syrup analysis, pharmaceutical laboratories, chemical laboratories, quality-control departments, research laboratories and educational laboratories.

The 0–100% Brix measurement range makes the instrument particularly useful for testing sugar solutions, beverages, syrups and other samples where Brix determination is required. The refractive-index measurement capability also makes it suitable for general liquid analysis and quality-control applications.
