Application Importance of EC/TDS in Brewing

Total dissolved solids, or TDS, is a measurement of the total concentration of dissolved substances in water. This can include minerals, salts, other organics, and even some chemical residues. Ground and surface waters contain high minerals and sometimes organic materials and are subject to pollution by human activity. One the other hand, municipal plants are often regulated by law to disinfect or pre-treat water with chemicals, removing contaminants that would adversely affect taste or health. These additives that serve to make drinking water safe can be an issue for brewers as disinfectants can result in off-flavors in the brew. The upside is that TDS can provide you with an indication of the gross mineralization of your water. The downside is that TDS is not ion specific.

Monitoring your TDS is a good way to be alerted to any unusual changes in your water supply. Additionally, a high TDS value can indicate water that is more corrosive to equipment and prone to scaling. Water to be used for brewing should have less than 500 ppm TDS.

Some brewers may wish to use selective water treatment options, such as reverse osmosis systems, to remove the minerals from incoming water in order to redesign the water profile. This can be achieved by adding brewing salts and bicarbonates. The ability to define the water profile allows for a diverse array of beer styles.

Process Control

Process Monitoring EC/TDS Mini Controller

With the option of manual or automatic dosing modes and a dosing relay that activates when the user-programmed set point is exceeded, the mini process controller is a great option for worry-free continuous monitoring of TDS and EC of incoming water sources. Terminals on the rear of the controller allow for simple wiring and the compact size makes it ideal for any space. Other features include:

  • Adjustable dry contact dosing relay
  • Overtime control system prevents overdosage
  • Automatic temperature compensation of readings
  • Multi-colour LED for indicating if the meter is in measurement, dosing, or alarm mode

Calibration Solutions

Conductivity Calibration Solution

Accurate conductivity (EC) and Total Dissolved Solids (TDS) measurements are only as good as the calibration standard used. EC/TDS standards are susceptible to change due to contamination. For calibration we offer a variety of packaging sizes based on your use.

  • All solutions sealed to prevent any air from entering the solution
  • Solutions are made by Hanna Instruments and are traceable to NIST standard
  • Available in variety of sizes from single use 20 ml sachets to a 1 gallon bottle
