Even at night! One NEW NI Supply ZGRS-10ATC dual scale portable Salinity Refractometer in a blue, foam-lined hard case. The ZGRS series of portable refractometers is designed to measure the salinity of sea water and saline solutions of similar concentration. One scale checks the NaCl levels with the range of 0-100 ppt (with 1 ppt scale divisions) and the other scale gauges Specific Gravity with a range of 1.000 to 1.070 (+/- 0.001 accuracy). Both enable the direct determination of salinity in water that contains dissolved salt and little or no other dissolved solids. Hydrometers are OK, but they can be very inaccurate. The NI Supply ZGRS-10ATC is designed to be very accurate to protect your investments! Simple and easy, take the guess work out of testing the salinity! All ZGRS models use ambient light, AND HAVE A BATTERY POWERED INTERNAL LIGHT which makes testing samples a snap in any light condition! Models with the “ATC” suffix are equipped with “Automatic Temperature Compensation” for accurate measurements without recalibration after shifts in ambient working temperature (field use). Heavy Duty + Internal Light = Unique Design! The reinforced forward hinge makes for fewer parts AND is 90% LESS LIKELY TO BREAK THAN OTHER MODELS! This model is also a HEAVY DUTY integrated design made of an extra ounce of machined aluminum. It also has the advantage of having an internal light! This feature allows you to flick the side button to have light whenever you need it. No more squinting to see the scale! Perfect for testing in low light environments or the professional who needs the best tool around! This model is ONLY available at VERY FEW sources! Get yours today at Wholesale prices! High Quality!
