อุปกรณ์วัด pH (Combined instrument for measuring pH and ORP)

HI 98121
Combined instrument for measuring pH and ORP

The series Combo waterproof tester combined with advanced features, the model includes HI 98121, which simultaneously measures pH and redox potential.
HI 98121 also measures the temperature and constantly shows on the large screen at two levels.
electrode pH, equipped with a splicing fiber renewable, is easily and quickly removable for replacement with the key provided. The temperature sensor, housed in a metal tube, has fast response times thanks to its outer position.
instrument works with common batteries and power displays the percentage of remaining charge to keep under control the operating status.
L ‘indicator of instability of the measure used to detect reliable readings. Designed with a style ergonomic, HI 98 121 is able to float thus making it easier recovery in case of accidental fall into the water.
