The Refracto 30PX and 30GS are compact hand held refractometers. Easy to use, samples can either be added to the measurement cell or the sensor can be immersed directly into the fluid with the result being displayed on a backlit LCD display as soon as the measurement key is pressed. Reftracto 30PX has an optical glass measuring cell whereas the 30GS has a sapphire measuring cell which extends the measuring range and speeds up temperature measurement. Key features include:

• Clearly labelled panel makes operation =easy and efficient
• Refracto automatically compensates the refractive index reading to 20°C or any other temperature the user defines
• Temperature range 10-40°C, resolution 0.1°C
• 30PX has an optical glass measurement cell whilst 30GS has a sapphire measurement cell which extends the measurement range
• Stores upto 1100 results and, using software provided, can then transfer to a PC, Infrared / RS232 converter available as an accessory
