ATAGO® PAL‑89S Digital Propylene Glycol Refractometer

ATAGO® PAL‑89S Digital Propylene Glycol Refractometer

The ATAGO® PAL‑89S is a digital handheld refractometer designed for fast, accurate measurement of propylene glycol concentration and freezing point in °F. The main scale displays propylene glycol (% V/V), while the secondary scale displays freezing point. As stated in the manual, “The main scale indicates the concentration of Propylene glycol and the secondary scale indicates the freezing point.” Automatic Temperature Compensation (ATC) ensures stable readings across the operating range, and the IP65 water‑resistant housing allows easy cleaning under running water.

Key Features

• Dual‑scale measurement: propylene glycol concentration and freezing point
• Automatic Temperature Compensation (ATC), 50–104°F (10–40°C)
• Fast 3‑second measurement
• IP65 water‑resistant design (not submersible)
• NFC data output with 100‑record memory
• Backlit display (30‑second auto‑off)
• Requires only water for zero‑setting
• Compact 100 g handheld design

More About This Item

The PAL‑89S requires only ~0.3 mL of sample and provides immediate readings of propylene glycol concentration and freezing point. Measurements stabilize once the prism acclimates to sample temperature — “Wait for approximately 20 seconds… measurements will stabilize once the instrument acclimates to the sample temperature.” The sapphire‑coated prism and spill‑resistant sample stage support routine industrial use. NFC output allows transfer of date/time, glycol %, freezing point (°F), and prism temperature to compatible devices.
