Stopped working after couple of usage
We bought this equipment to check conductivity of water. After using it for couple of times, the instrument stopped working. If you are buying it, be aware that this will not serve you for a long time. Note: REMOVE BATTERIES AFTER USAGE. BATTERIES THAT COME WITH THIS INSTRUMENT LEAKED THE SAME DAY, EVEN WHEN THE INSTRUMENT WAS SWITCHED OFF.

Possibly USED product.
Everything else came seal packed but why is there crystallisation around the plastic cover/cap? Why are there water droplets and water near the sensor and inside the plastic cover/cap? It seems like this product has been used or tested prior to shipping. There are fingerprints all over the instrument.
