Hach 145300 Total Hardness Test Kit, Model 5-B

Model: 145300   |    Mpn: 145300   |    Ean: 0628586635708   |    PartNumber: 145300   |   Asin: B008FM7WLU

Water hardness is caused almost entirely by calcium and magnesium ions. Other di- and trizalent metals have a similar effect, but usually are not present in high enough concentration in potable waters to cause problems. Hardness increases soap consumption in laundries and causes scale in boilers. Hardness test kits include the inexpensive Models 5-B and 5-EP designed for those needing quick checks on the efficiency of water softeners. More sophisticated test kits allow the determination of total hardness as well as calcium and magnesium (by difference).

Mohs' Hardness Test Kit for Industrial Applications

Model: HD2   |    Mpn: HD2   |    Ean: 0753807504157   |    PartNumber: HD2   |   Asin: B00Q26HFAO

This tool is used in industry to determine the Hardness of a material according to Mohs' scale. The kit contains 8 different Mohs' Hardness Points, from Mohs 2 through Mohs 9. These points are used in a 'scratch test' on the material. For example, if the number 6 point scratches a particular material, but the number 5 point does not, then your material has a Mohs' Hardness value of about 5.5. A common use of this tool is in Concrete Hardness Testing to guide the technician in selecting the optimal abrasive to use in the concrete polishing. Other examples of industrial use of this Mohs' Hardness Test Kit - on touch screens, faucet finishes, and countertop materials. This kit comes packaged in a rugged molded Plastic Case with permanent Instructions, along with a Mohs' Hardness Table of common natural and man-made materials.

Features

  • This set includes 8 Mohs' Hardness Points from Mohs' 2 through Mohs' 9, nicely mounted in nickel-plated Brass, color-coded, number-stamped, double-ended Pin Vises. Also includes two Hardness Plates of Mohs' 3.5 and 5.5, a 100x Sharpening Stone, along with laminated Instructions permanently affixed to inside of case, a Table of Industrial and other materials sorted by Mohs' Hardness, all compactly packaged in a molded Plastic carrying Case, designed for use in rugged workplace environments.
  • The Hardness Points are made of Metals and Alloys of equivalent Mohs' Hardness as the mineral standards, so the points will not break off, and they can easily be re-sharpened, and ultimately replaced after many years. This beautiful and thoroughly conceived tool is made for the opposite of planned obsolescence.
  • This is probably the foremost tool used in the Concrete Polishing industry, for determining the Mohs' Hardness of the underlying Concrete matrix. We especially configured it with customized components, Instructions, Hardness Tables, and Carrying Case for Industrial use.
  • IMPORTANT: For Rockhounds and Mineral enthusiasts, instead, we highly recommend our especially configured Deluxe Hardness Pick Set and Mineral Identification Kit. Just search Amazon using that keyword string.
  • One year Warranty, 30 day Money-Back Guarantee

Fowler Full Warranty 52-760-000-0 Hardness Tester File Set, 0.157" Diameter, 7" Length, Set of 6 Files

Model: 52-760-000-0   |    Mpn: 52-760-000-0   |    Ean: 0646795125582   |    PartNumber: 52-760-000-0   |   Asin: B00B5HQYAM

The Fowler 52-760-000-0 Fowler's Hardness Tester File Set is an inexpensive, easy-to-use method for determining material hardness by sliding the file across the object's surface. Six color coded files indicate hardness from 40 to 65 HRC. Conveniently packaged in a leath er-like case with a velcro lined flap, the files are approximately .157" in diameter and 7" in length (4.3 x 175mm).



Testing Procedure:

* Run the Black file (65 HRC) over test material. If it marks the material, the material is less than 65 HRC.

* Try the Blue file (60 HRC). If it does not mark the material, it indicates that the file is softer than the material and is between 60 and 65 HRC.

* If the Blue file (60 HRC) marked the material, continue testing with the Green (55 HRC), Light-Green (50 HRC), etc. until the material is not marked. The approximate hardness of the material is between the file that marks the material and the file that slides over the material.

* Included chart also shows the appropriate Vickers Hardness (HV).
