Waterproof Digital Refractometer Brix (Sper Scientific)

Rugged & Waterproof Brix Meter for Field Testing

This waterproof digital refractometer is engineered for food, beverage, and agricultural quality control in wet field environments. The IP65-rated rubberized case protects electronics from moisture and splash during harvest monitoring, fruit receiving, and juice processing. Measure samples as small as 1 mL with laboratory accuracy - no need to return to the lab for inline testing.

Key Features

• Automatic calibration to distilled water with one-button operation
• Automatic temperature compensation ensures accurate readings across field conditions
• Automatic 3-minute shutoff preserves battery power during long field days
• Large LCD screen displays sample temperature first, then measurement results
• Rechargeable Lithium Ion battery provides 50,000 tests (approximately 6 months continuous use)
• Ships ready to use with instructions, carrying case, transfer pipet, AC power adapter
• Available in two ranges: 0-60% Brix for fruit and juice, 0-88% Brix for concentrated sugars and honey

Housed in a protective rubberized IP65 Waterproof case to safeguard the electronics from wet environments and makes for easy clean ups. Measure samples as small as 1 ml, in the field with laboratory accuracy. Sample temperature is initially displayed on the large LCD followed by the measurement results. The sophisticated microprocessor provides automatic calibration, automatic temperature compensation and automatic shutoff (after 3 minutes). Features one button calibration to distilled water and indicates when the battery is low. Powered by a rechargeable, long-life, Li (Lithium Ion) battery providing 50,000 tests or about half a year use on a single charge. Comes ready to use with instructions, carrying case, transfer- pipet and an AC power adapter.

Frequently Asked Questions: Digital Refractometer For Brix Testing

What's the difference between the 0-60% and 0-88% models?

The 0-60% covers most fruit juice, soft drinks, and wine. The 0-88% handles concentrated sugars, honey, and high-Brix products. Choose based on your typical sample range.

How do I know when the battery needs charging?

The meter displays a low-battery indicator on the LCD screen. A full charge from the included AC adapter takes approximately 2 hours.

What's "automatic temperature compensation" and why does it matter?

Brix measurement is temperature-dependent. This refractometer automatically adjusts readings based on sample temperature so you get accurate results across field conditions.

Is the IP65 rating good enough for rainy field use?

Yes. IP65 means dust-tight and resistant to water jets from any direction. It handles rain, spray, and wet conditions without damage.

Can I use this for honey or very thick samples?

The 0-88% model is designed for honey and concentrated products. Use the transfer pipet to place a small sample on the measurement window. Clean thoroughly after testing thick samples.
