Máy Kiểm Tra Nước Siêu Tinh Khiết HI98309 (UPW) (0,000-1,999 µS / cm)

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
