D-D Pen Type Digital TDS MeterA TDS Meter measures the amount of Total Dissolved Solids (TDS) in a solution. This is used to determine the purity of the water produced by your RO unit and will give an indication of when your DI resin or membrane life is coming to an end. It also is a handy digital thermometer to measure or calibrate the temperature of your tank.

A TDS Meter measures the amount of Total Dissolved Solids (TDS) in a solution.

This is used to determine the purity of the water produced by your RO unit and will give an indication of when your DI resin or membrane life is coming to an end. It also is a handy digital thermometer to measure or calibrate the temperature of your tank.

Since dissolved ionized solids like salts and minerals contribute to the conductivity of a solution, a TDS meter measures the conductivity of the solution which is then converted to a TDS reading.

TDS is directly related to quality of water i.e., the lower a TDS figure, the more pure the water. As an example, reverse osmosis purified water will have a TDS between 0 and 10, whereas tap water will vary between 20 and 300.

  • The D-D TDS meter is supplied pre calibrated

  • Measures TDS from 0-9999 ppm ( 0-1000 in increments of 1ppm, 1000-9999 in increments of 10ppm)

  • Measures water temperature with a digital readout

  • Long battery life with auto shut off feature

  • Automatic temperature compensation

  • Highly accurate

  • Supplied complete with carry case

  • Essential equipment for monitoring RO unit production and the remaining life of Di resin

Great for shed organizing
Size: 4.5", Style: Open, Size: 4.5", Style: Open
We recently upgraded to a conex/shipping container/metal shed and needed a way to organize all of our yard tools. These work great, the weight holds a lot of items, could be a little longer but we were impressed with them holding everything for over a month now and not moving.

Good product. Know the limits.
Size: 6 Inch, Style: Open
These are very nice. Sure beats drilling holes in your steel. However, 45lb is a stretch. Will easily hold 25lbs. However 35+ is a stretch, especially if your walls shift a little due to be close to a door. Will definitely order more, just important to understand the limits. Thanks.

Finally, a product that meets all of its advertised claims!
It seems to me like this product is always out of stock. Of the ones I have received and been able to use. They work as advertised and hold an incredible amount of weight. It is very easy to put them on and off, but once they are latched down, you could not remove them by hand without bending the hooks I would like to have a few more boxes to use in my steel building.

Magnet hooks you need!
Size: 4.5", Style: Open
I have been using these all over our shop and helps keep chords, tools and other items off the floor and more organized. I like the ease of the magnet, and it looks like. Built to last. I wish they were not so expensive.
