Specific gravity hydrometers are commonly used in industries such as food and beverage, chemistry, pharmacology, transportation, refrigeration and more. Available in a variety of models measuring specific gravity / relative density (g/cmᶟ) of liquids lighter and heavier than water in various ranges from 0.690 to 3.000, they are made of lead free ballast and glass. These plain form hydrometers are individually serialized and have a temperature standardization of 60 degrees F (15 degrees C). DURAC Hydrometers are hand inspected by our U.S. quality team in our exclusive triple accredited/registered ISO/IEC 17025:2005 and A2LA Accredited Calibration Laboratory; internationally recognized and accepted by the signatory economies of the ILAC/MRA and located in our ISO 14001:2004 Environmental Management System registered facility. They are packaged with a multi-language (English, French, German, Italian, Portuguese, and Spanish) Statement of Accuracy indicating accuracy traceable to NIST. Note: Plain form hydrometers should be stored in a clean, dry, safe place. They should not be subjected to extreme temperatures.

Manufacturer: Gain Express Holdings Ltd. Brand: Gain Express Model: A018351

This Dual meter is designed to measure the Conductivity and temperature (°C/°F) display simultaneously on its clear LCD. It has an IP65 Rating, waterproof and dustproof housing and waterproof membrane keypad. Default to Auto-ranging when power on. It determines and selects a range that gives the greatest resolution and accuracy. You can also opt to manual ranging and choose the range you prefer. For example you prefer a reading display of 0.50mS insteaqd of 500uS just press a button to select the mS range. Accuracy is a percent of full-scale, using the meter in its lowest range will result in the greatest accuracy. Perfect for both consumer or commercial use such as in water systems, aquaculture, drinking water production, monitoring the cleanliness of swimming pool & spa, nutrient, hydroponics, household, office, aquariums, teaching material for physics and chemistry lessons, galvanic shop, ionized water and laboratory. >The values are well readable with the large clear display.

Danger and excitement lurk around every bend of the river in White Water. Race down a deadly river carefully navigate your rafts through the obstacles, trying to keep your paddles and your crew inside the raft. In the game White Water each player directs the actions of four courageous rafters. Each raft in the race contains four crew, with two crew from you and two from another player. Players control the crew within a raft, but also may use Energy cards to additionally help one raft or the other. Dice represent the effects of hazards you encounter, and even your best-laid plans can be spoiled by another raft pushing you a direction you don't want to go. Designed by Frederic Moyersoen, designer of Mayfair's popular Nuns on the Run, Bacchus' Banquet, White Water is the game where players ride the rapids and earn points for getting their rafts and passengers home safely, navigating through treacherous waters including rocks, driftwood and the dreaded whirlpool! Contents: Rules 14 Victory markers 12 Overboard markers 6 Paddle markers 9 River boards 1 start board 8 river boards 12 raft tiles 24 Action cards 18 Energy cards 6 Rafts 3 dice (blue, red, black)
