The TDS/PPM meter is a tremendously versatile and multi-use monitor. It is small enough that it can be used as a portable meter in the field, a spot tester in the lab, or be used to continuously monitor the TDS/PPM values directly in your reservoir.
With a range of 0-1990 ppm, the TDS meter comes with automatic temperature compensation (ATC) and 1 point manual calibration. Supplied complete with MA811D/1 TDS probe, 110 volt power supply, unit mounting kit, probe holder, 1 20 mo-1382 ppm sachet calibration solution and screwdriver for calibration.
The BEM401 features a mounting kit, which allows it to be mounted to a wall or the side of a tank/resevoir, as well as an electrode and holder. Its large, easy to read LED display, combined with a smaller, lighter and more ergonomic case add to the versatility of this meter.
