  • Good gauge By Check your filter on 9/6/2017

    I use this to keep an eye on my ro/di filter. Good to know when your media needs changing.
  • Great product By SomeOldGuy on 8/4/2017

    I purchased this meter just after moving into our new location. I was curious about the state of our water. Thanks to this meter I now know.

    It's amazing easy to use, turn it on, put it into a container of water and I have my answer.

    If you need/want to know how much TDS (Total Dissolved Solids) are in your water, this is a great way to find out.
  • Very easy to use By Reefer250 on 1/19/2017

    Very easy to use has a nice bag to put it away
  • Not Accurate By Aaron on 4/13/2016

    I purchased this to verify my inline TDS meter was working properly. When I got it they were both off by 10 PPM. This was HMs response when asked about it: These meters are accurate within 2%, but have a range of 500ppm TDS, meaning 10ppm TDS is within that range of error. The product is not as accurate as hobbyists are looking for.
  • Great By Fred on 3/13/2016

    Was curious if my Ro di was doing good and I bought this. Happy I did. Easy to use.
  • Works! By Paperpimp on 3/7/2016

    This meter works good for me! easy to use and seems well built!
  • working good By siknd on 2/6/2016

    Have had this product for a few months now its been working great bought it to show friends and family the total dissolved solids in their drinking water and tap water also used it to double check my RO system make sure that the TDS from the meter on my ro system and from my handheld probe are the same. I have also use the temperature gauge on the hand held TDS meter to double check my temperatures from my tank probes and it has read within .1° of the two probes on the tank
  • Mine was defective By Yak on 11/23/2015

    I read all the great reviews on tihs product, tried it out, and it was just...not...accurate. Like my local LFS was reading 90 PPM. BRS was great to deal with though, gave me a full refund on the product. They must know a few go out defective.
  • Works great By Ray on 11/10/2015

    product as ordered and works great.
  • Great and accurate. Must own By Walter on 9/5/2015

    Was never sure what my home, fridge, ro drinking, or what my finished product water tds was. I was testing everything like crazy when I received this. Is very accurate with my finished product water at zero tds. Now I carry it with me everywhere due to my scientific curiosities. Thank you brs for another great product.
  • EASY AND WORTHWHILE By Claude on 12/15/2014

    Easy to use, accurate, must have.
  • works great By Mike on 10/29/2014

does this need calibration fluid?
Question by: trent on Apr 26, 2014 3:50:00 PM
Hi Trent,
No, they come pre-calibrated from the factory. Given the sensitivity of the instrument and the process involved its really recommended to not mess with the calibration or your really likely to make it less accurate.

Does this pen require the electrode to be stored in a solution?

Great question! The electrode does not need to be stored in a solution.
