Accurately measures freshwater impurities. Anything that is not water (ie. calcium, nitrate, silica, magnesium), regardless of the amount, will be measured. Meter is great for discus keepers who want to monitor trace elements that are added to to pure water. Also can be used to check RO membranes.
- The most precise method to measure fresh water purity.
- Measures liquid conductivity within two ranges: 0 - 1,999 uS and 20,000 uS (micro-siemens).
- Accuracy to +/- 1% of the displayed reading.
- Complete with temperature compensated probe and 1 meter cord.
- Nine volt battery supplied by Aquarium Instruments
