DIGITAL ABBE REFRACTOMETER	DR-A1
Cat No.1310

By very simple operation that needs only to set the boundary line of refraction at the cross hairs, this refractometer directly indicates a measured value (in refractive index or Brix %, selective) in digits together with temperature on the display. This refractometer enables anybody to carry out measurement easily without reading of analog graduation. *Dispersive value cannot be measured by this refractometer.
Measurement range: Refractive index(nD) 1.3000 to1.7100 Brix(%) 0.0 to 95.0%(automatic temperature compensation is executed at 5 to 50°C) Minimum scale: Refractive index(nD) 0.0001 Brix(%) 0.1% Measurement accuracy: Refractive index(nD) ±0.0002 Brix(%) ±0.1% Measurement temperature range: 5 to 50°C Size and weight: Main unit 13x29x31cm, 6.0kg

ABBE REFRACTOMETER	1T
Cat No.1210

The 1T is an Abbe refractometer of standard type, measures refractive indices of liquids and solids quickly and accurately. It is designed to give refractive indices of D line without using a sodium lamp.
Measurement range: Refractive index(nD) 1.3000 to1.7000 Brix(%) 0.0 to 95.0% Minimum scale: Refractive index(nD) 0.001 Brix(%) 0.5% Measurement accuracy: Refractive index(nD) ±0.0002 Brix(%) ±0.1% Measurement temperature range: 0 to 50°C Size and weight: Main unit 13x18x23cm, 3.4kg

Designed for use with compounds which require measurement at high temperature.
Measurement range: Refractive index(nD) 1.3000 to 1.7000 Brix(%) 0.0 to 95.0% Minimum scale: Refractive index(nD) 0.001 Brix(%) 0.5% Measurement accuracy: Refractive index(nD) ±0.0002 Brix(%) ±0.1% Measurement temperature range: 0 to 120°C Size and weight: Main unit 12x20x25cm, 5.8kg

The type 3T has been developed to give improved measuring accuracy and ease of use. This has been achieved by making fundamental improvements to the optical system, utilising a larger scale, incorporating a high intensity lamp and using a double control knob to give quick and finer control.
Measurement range: Refractive index(nD) 1.30000 to 1.71000 Brix(%) 0.00 to 95.00% Minimum scale: Refractive index(nD) 0.0002 Brix(%) 0.1% Measurement accuracy: Refractive index(nD) ±0.0001 Brix(%) ±0.05% Measurement temperature range: 0 to 50°C Size and weight: Main unit 12x31x34cm, 9.0kg

ABBE REFRACTOMETER	4T
Cat No.1240

R & D on new materials for modern technologies is being actively conducted in every industry. Many of these materials (especially polymer film and related materials) are of high refractive index-often too high for the existing Abbe refractometers. But these are now covered with the nD1.4700 to 1.8700 range of the type 4T.
Measurement range: Refractive index(nD) 1.4700 to 1.8700 Minimum scale: Refractive index(nD) 0.001 Measurement accuracy: Refractive index(nD) ±0.0002 Measurement temperature range: 0 to 50°C (Temperature range available of the circulating water) Size and weight: Main unit 13x18x23cm, 3.4kg
