MEASURES TOTAL DISSOLVED SOLIDS
The TDS Pal meter is used to measure the conductivity of water and hence the level of total dissolved solids in solution.
A comparison of TDS levels between mains water and system water can be used to confirm the efficiency of a power flush. After flushing a heating system, a sample of system water should have a TDS reading within 10% of the mains water supply.
A TDS meter can also be used to ensure correct dosing of inhibitor or flushing chemical into a system of unknown volume. This is particularly useful in commercial heating and cooling systems where system data is often unavailable.
- Microprocessor-based
- Direct full-scale readout eliminates guesswork
- Automatic Temperature Compensation (ATC)
- Dip-type sensor allows direct immersion into sample.
- Stainless steel electrodes for good chemical compatibility and durability
INSTRUCTIONS FOR USE:
- Take a sample of at least 100cc of the water to be tested in a suitable clean beaker/vessel to a depth of approx. 5cm.
- Remove the protective cap from the TDS meter.
- Turn the TDS meter on by sliding the ON/OFF switch located on the top of the meter.
- Immerse the TDS meter into the sample of water without touching the bottom of the sample beaker or vessel.
- Stir gently and wait for the display reading to stabilise. The TDS meter automatically compensates for temperature variations, and variations on the meter display can be due to the temperature sensor adjusting to the sample temperature.
- Read the figure from the display and multiply by 10 to give the parts per million of total dissolved solids (this may also be expressed as mg/litre).
