HI98129 (Combo) · HI98130 (Combo) pH/EC/TDS Testers • Waterproof · Designed to float if accidentally dropped in a tank • Automatic Temperature Compensation · All readings are compensated for variations in temperature · Temperature displayed in °C or °F along with pH reading • Stability indicator · Meter displays a 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 shuts off if there is not enough power to get an accurate measurement • Battery % level at startup • Low Battery Indicator • Auto-off · Automatically shuts off after 8 minutes of non-use to maximize battery life The HI98129 and HI98130 are waterproof testers that offer high accuracy pH, EC/TDS, and temperature measurements in a single tester; no more switching between meters for your routine measurements. These floating, waterproof combination testers have an easy-to-read LCD and an automatic shut-off. pH and EC/TDS readings are automatically temperature-compensated. These testers feature a replaceable pH electrode cartridge as well as an EC/ TDS graphite electrode. The replaceable pH cartridge means this tester does not need to be discarded when the pH sensor is exhausted. The EC/TDS conversion factor is userselectable, as well as the temperature compensation coefficient (β). 1 Testers and Monitors 1.8 | www.hannainst.com testers
