AQUASHOCK™ METERS AND KITS
AquaShock® meters have been designed and tested to ensure accurate, reliable water quality measurement under any conditions. The integral soft-grip outer layer provides a firm grip, even in wet environments, and an anti-shock LCD, and other high-end components, further ensures that AquaShock® is fully shockproof. AquaShock® meters are also IP67 waterproof and will float if accidentally dropped in water. The screw-down probe connections are watertight when used with AquaShock® probes. When a waterproof connection is not needed, any BNC-connected probe can be used. The latest high performance electronics give AquaShock® meters extremely stable and accurate readings. Results are easy to read, in any light, on the large LED backlit display. Powered by a long-lasting, environmentally friendly, rechargeable, Lithium-Ion battery.

AquaShock® meters are very intuitive and include all the functions you will likely ever need including:

• Review of 99 memories, min-max-ave, directly on the meter's display
• Internal clock and calendar
• °C & °F
• Auto-ranging
• Automatic and manual temperature compensation
• Hold

You will find no metre more rugged and reliable than AquaShock®.
Dimensions: 210 x 108 x 57 mm. Weight: 476 g.

Features

• Floats
• Fully Shockproof. The integral (double injection molded) soft-grip outer layer provides a firm grip, even in wet environments and helps protect the internal components from shock. A reinforced internal structure and anti-shock LCD with a protective window further ensure that AquaShock® meters will not be damaged when dropped from any angle.
• IP67 Waterproof including probe connections and will float if accidentally dropped in water.

COMPACT DIGITAL REFRACTOMETERS
These pocket digital refractometers measure brix, salinity and a wide variety of other parameters in the field with laboratory accuracy. As small, light and simple to use as optical refractometers, but with the precision of a digital readout.
Samples can be as small as 1.0 mL. 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 shut-off after 3 minutes. (The temperature is given in Fahrenheit only, but since the compensation happens automatically, the actual temperature is not really important.)
A sturdy water resistant case protects the electronics from wet environments and makes for easy clean-ups. All models feature one button calibration to distilled water and indicate when the battery should be replaced (8000 readings).
Comes ready to use with distilled water, transfer-pipette, AAA battery, instructions and a carrying case.

LABORATORY DIGITAL REFRACTOMETERS
These Laboratory refractometers measure brix, salinity, refractive index and clinical parameters with full scale accuracy of 0.2% using CCD scanner (= linear scanned array imaging) technology. Samples can be as small as 0.4 mL.
Measurement results, unit of measure and sample temperature are all displayed on the large LCD and visual alarms are indicated by a red LED. The sophisticated microprocessor provides automatic calibration, automatic temperature compensation and automatic shutoff (after 3 minutes). A sturdy water resistant case protects the electronics from wet environments and makes for easy clean ups. All models feature one button calibration to distilled water and indicate when the battery should be replaced (5000 readings).
Supplied ready to use with a 9V battery, distilled water, transfer pipette, instructions and a protective case.
Dimensions: 180 x 100 x 65mm
