Refractometers Rudolph Research J47, J57, J157, J257, J357, J457, etc.
Rudolph Research Analytical manufactures refractometers for both research laboratories and quality control laboratories. The J series refractometers differ from traditional refractometers in the absence of replaceable moving prisms, which increases the measurement accuracy and durability of the equipment.
