Water Purity Tester HI98309

In stock

The HI98309 UPW is the first pure water tester/conductivity meter to measure in 1/1000ths of micro-Siemens and provides on-the-spot and fast checks for minute traces of contamination in your water, assuring high quality of finished products in processes. A rugged, pocket-sized tester that features graphite electrodes to reduce polarization effects. The HI98309 comes already calibrated, done with freshly prepared low-conductivity solutions in factory due to the high instability of calibration solutions in the UPW range (below 2 µS/cm).

  • Exposed temperature sensor for fast response
  • Accurate readings of ultra low range 0.000 to 1.999 µS/cm
  • Factory calibrated
The HI98309 uses a conductometric measurement to determine the purity of water. The HI98309 Ultra Pure Water tester (UPW) enables users to check the purity of water, best suited for electronics and semiconductor industries. This tester is housed in durable casing that provides excellent protection against harsh industrial environments.
