Extech RF153 Data Sheet

RF153 Digital Brix

Refractometer

Take quick and accurate % Brix or Refractive Index (RI) measurements of dissolved sucrose level in liquids for beverage and food production, determine maturity of fruits and plants, or control the concentration of industrial ﬂuids (such as cutting coolants, hydraulic ﬂuids, and antifreeze) to extend equipment life and prevent corrosion. Fast three second response time, the LCD displays %Brix or RI and Temperature. The RF153 ﬁts in the palm of your hand and it features built-in ATC, single Zero calibration, prism cover, and auto memory storing 10 readings. Rugged low maintenance water resistant (IP65) housing with convenient side spouts for easy drainage.
