Laxco™ Handheld LED temperature compensated Analog Salinity Refractometer

Not yet rated

Refractometers have been used for measuring the concentration of solutions for more than a century. Their primary purpose is to measure the degree at which light bends as it passes through a medium, and is used in a wide range of applications and industries as a quality control and diagnostic tool.

Laxco Analog Lighted Refractometers are designed by US engineers and include many features packed into a handheld device.

Each unit is inspected in the United States by a factory qualified technician under a rigid quality control process to ensure accuracy and performance.

Key Features:

Sealed calibration screw is locked on the bottom of the unit to prevent water from entering into the system
Quickly calibrate the instrument with a turn of a screw, and distilled water
Comfortable rubber eyecup blocks out ambient light and allows for crystal clear viewing of readings
Automatic temperature compensation prevents the need for constant re-calibration of the instrument. As the ambient temperature changes, the scale will automatically compensate for the difference in the degree of refraction. This ensures an accurate reading every time
All metal construction and water-resistant seal between prism and main body protects and prevents damage to internal objective lens
Flat bottom allows the instrument to be set on a flat surface without the worry of it rolling
Rubber hand grip is comfortable, easy to grasp. Its non-slip pattern grip reduces that chance of accidentally dropping the instrument
One-piece U-shaped metal hinged daylight plate provides durability of frequent opening and closing. Two screws allow the daylight plate to be easily replaced in case of accidental damage
Machined hole for hanging the refractometer in a convenient location
Ball bearing hinged daylight secures the daylight plate in the up and down position
Magnified scale and all glass optics creates the sharpest readings on the market
Push bottom monetary switch allows for easy operation of the LED illumination
Focusable eyepiece allows for crisp focus of reading line
Carrying lanyard
Two sample applicators are mounted to the bottom side of the refractometer, for convenience
LED illuminates the scale without the need for ambient light
Operates both with ambient light and LED
Portable, easy to use design
Salinity Models:

Whether you are in Aquaculture, Food processing or wildlife management Laxco Lighted Analog Handheld Refractometers are designed to measure salt levels in water and other saline fluids accurately and repeatedly. The dual scale allows for direct readings of specific gravity, and concentrations in parts per thousand.

Specific Gravity: 1.000ppt to 1.070ppt with granularity to measure down to 0.001 divisions at a ±0.001 degree of Accuracy
Salinity: 0 to 100ppt with granularity to measure down a 1ppt divisions at a ±1ppt degree of Accuracy
Laxco™ refractometers are formally Westover Scientific refractometers
