ATR-Touch P
Laboratory Refractometer with Integrated Peltier-Thermostat

The critical angle refractometer ATR-P is especially designed for applications in the sugar industry. The Complete system consists of the PURE-S measuring head and the "L-Display" electronic unit. As an alternative to the "L-Display" electronic unit, the PURE-S measuring head can be connected to a PC or laptop. In the minimal version configuration and calibration are performed using a supplied basic-software. Much more comfortable and more extensive is the PC version of the "L-Display" software

Features of ATR-B Automatic Refractometers

  • High-performance robust Refractometer for the determination of mixing ratios (mass percent)
