HI98130 COMBO Tester for pH/EC/TDS/C° up to 20 mS, waterproof

The HI98130 is a highly accurate, waterproof combo ph ec tester that can also measure EC/TDS in the high range (0.00 to 20.00 mS/cm EC/ 0.00 to 10.00 ppt TDS) and temperature. This floating, waterproof combination tester has an easy to read, LCD and an automatic shut-off. In addition, pH and EC/TDS readings are automatically temperature compensated (ATC) to prevent temperature-related variations in your measurements. For EC/TDS readings, the EC/TDS conversion factor (CONV) is selectable by the user, as well as the temperature compensation coefficient ? (BETA). Replaceable pH Electrode Cartridge The HI98130 pH and conductivity tester features an easy to replace pH electrode cartridge with an extendable cloth junction. The extendable cloth junction helps increase electrode life and the replaceable pH cartridge means that this tester does not need to be thrown away when the pH sensor is exhausted. Also, the sturdy, snap-in connector means there are no pins to bend or break! High Accuracy EC/TDS Graphite Probe The graphite conductivity probe provides greater accuracy because it cannot be contaminated by salt deposits in the solution. The exposed temperature sensor provides fast response times and guarantees highly accurate temperature compensated readings. Features at-a-glance Stability indicator Meter displays a clock tag that will disappear when the reading has achieved stability HOLD button Freezes reading on the display to allow recording of measurement BEPS (Battery Error Prevention System Meter will automatically shut off if there is not enough power to get an accurate measurement Battery % level at startup Low Battery Indicator When the level is below 5%, the battery symbol on the LCD blinks to indicate a low battery condition.
