Manufacturer: Bel-Art Brand: SP Scienceware Model: B61800-0000

Made from optical quality polycarbonate plastic material, these plain form hydrometers are durable and shatterproof making them ideal in situations where rough handling or contamination could be an issue, such as in the food or beverage industries. Available in models measuring specific gravity / relative density (g/cm3) of a variety of liquids in various ranges from 1.0 to 1.620, they have an easy to read black scale on yellow back to help avoid eye fatigue. At 300mm (12”) long, each hydrometer contains lead free ballast, is individually serialized, and has temperature standardization of 60 degrees F (15 degrees C). DURAC Polycarbonate Hydrometers are made and 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. Made in USA. Note: Polycarbonate hydrometers are not recommended for use with petroleum-based liquids or other corrosives that would potentially affect the plastic material. They should be stored in a clean, dry, safe place and should not be subjected to extreme temperatures.

Manufacturer: Extech Instruments Brand: Extech Model: PH100

ExStik pH tester features a flat pH sensor making it ideal for testing semisolids and surfaces. Flat surface also reduces the chance of accidental breakage of the electrode tip-perfect for rugged field use! Built-in smart chip simplifies calibration and error diagnosis. CAL alert notifies you when it is time to recalibrate ensuring accurate readings. Renew indicator tells you when it is time to replace the electrode. Built-in memory recalls up to 15 sequentially tagged readings. LCD simultaneously shows pH and temperature readings, plus an analog bar graph of pH values lets you view reading trends. Waterproof tester floats in water. Flat-surface electrode is great for semisolids, solids, and surface testing Built-in memory recalls up to 15 labeled readings. Smart chip tell you when to calibrate or replace your meter

After your order is confirmed,the product will reach you within 7--13 business days. Product Description: This is a Zahn type Cup Viscometer which are used to measure the flow behavior of liquids such as paints and is in very nice condition.Applicable to the construction site to quickly measure the viscosity of the paint to be sprayed; more widely used in electronic products, plastic coatings industry. The cup and Iwata spray gun together become essential plant construction tools. 1)Using a suitable solvent to wipe clean,when before or after the cup be used. 2)Put the cup into the container body 1- 5 minutes, to achieve thermal equilibrium of the cup body,then put the cup body vertical lift from the feedstock,the action should be fast and stable. 3)Timekeeping when the upper end of the cup leave from the surface of Liquid,and liquid should be kept out of the cup vertically,with the surface distance of not more than 150mm. 4)Stop timing when the first breakpoint occurs, and the difference between the two measured values should be less than 5% of the average. Attention: We will send the product to your as soon as possible. If you have any question, please feel free to contact with us . We will try our best to give you a satisfactory solution.

Liquid Color Standards range from water white through yellow to deep amber. Liquid Standards 1 through 8 are solutions of potassium (No Suggestions). They are light in value, have a very slight greenish hue and are most often used in testing unheated liquids. Standards 9 through 18 are solutions of ferric chloride and cobalt chloride; they are darker and are generally used to test varnishes, oil and resins which have reached color through heating.
