PTR Series of Refractometer - Peltier Controlled

Incorporating electronic temperature control by Peltier Cell technology.

The PTR range of refractometers has been engineered for high accuracy, excellent temperature stability, reliability and ease of use, The temperature range is controlled electronically using Peltier Cell technology, removing the need for an external thermocirculator, resulting in significant cost, space and energy savings.

All versions of the PTR refractometer provide electronic temperature control to extremely high levels of stability at any selected temperature between 15°C and 50°C. The simple to use PTR1a and PTR2aX are provided with a remote control unit for changing all of the instrument settings. The PTR46 and PTR46X can be set by the operator to any temperature over the full range. All versions continuously show the sample temperature on the backlit LCD display to a resolution of 0.1°C or 0.01°C, depending on whether RI is displayed to 4 or 5 decimal places respectively.
