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.

  • 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 great, accurate!
  • not accurate By toms on 9/8/2014

    Got tds meter to compare to one on my new brs 4 stage plus ro unit. Hand held not accurate at all. It read 68ppm on the filtered water and 75 on water supply in. I tested on local fish stores RO unit and same readings. I would not buy this tds meter
  • easy By valerie on 2/27/2014

    Ready to use as soon as you receive it. Very quick accurate readings.
  • This thing functions just as advertised By John on 12/31/2013

    In my opinion u can't have two many TDS meters. I've had a few different kinds in the past but when I bought my BRS 5 stage RO/DI system with the online tds meter I decided to go ahead and buy this handheld meter. Just like everything else they make, it's built sturdy, and it looks professional comings with its own pouch. I hope im not starting to get spoilt.
