Water Testing Equipment, pH Testers, Indicators, Meters and Electrodes from Industrial Water Equipment

HI 8427 is designed specifically to simulate pH & ORP electrodes and to confirm proper functioning of your meter. Standard pH electrode ranges are selectable with a dial on the front panel. The pH range is pH 0, pH 2, pH 4, pH 7, pH 10, pH 12 and pH 14 with the mV range being -1900 mV, -350 mV, +350 mV and +1900 mV. Manual temperature compensation from 0 to 50°C (32 to 122°F) allows temperature simulation. Provided with a universal BNC connector, this unit is also a high impedance tester, for cable and connector inspection with a leakage sensitivity of 109 ohm. The unique tester is a "one of a kind" in the industry that eliminates the need for very expensive megaohm meters. It is sometimes difficult to work out whether a particular malfunction is due to the meter or the electrode. If you have been in this position, the HANNA instruments® precision HI 931001 pH/ORP electrode simulator is the perfect solution for you. By simply connecting HI 931001 to your meter's input socket and turning the dials, pH readings can be simulated from 0 to 14 pH in 0.01 steps. The output signals all correspond to pH values at 25°C and your pH meter should display the same values that can be seen on the simulators LCD. For the mV range, HI 931001 can simulate output from -1000 to +1000 mV in 1 mV steps.

 

Chemical Test Kits for pH Measurement

The pH value of water is related to a large number of dissolved substances and is therefore a good indicator of water quality. In applications where water is treated chemically, the pH value should be measured continuously. In chemical reactions, the solids present in wastewater precipitate and the water is neutralized and decontaminated. During these reactions, the pH must be kept at the right value, since a solution that is too acid or alkaline may interfere with the precipitation of solids and will influence the efficiency of the process. HANNA instruments®’ line of chemical test kits covers the pH range between 3 and 10. The colorimetric pH kits are also available with an additional reagent against chlorine interference.
