The Hanna Instruments HI 98121 pH / ORP tester is designed for simultaneous pH and ORP measurements. The Hanna Instruments HI 98121 pH / ORP tester also reads temperature, which is continuously displayed on the dual level LCD. An encapsulated external stainless steel sensor, positioned in close proximity to the pH electrode provides fast response. The fiber junction can easily be pulled out and replenished when necessary. By using the provided electrode removal tool, the Hanna Instruments HI 98121 pH / ORP tester's pH electrode can be quickly replaced when fully depleted.
The Hanna Instruments HI 98121 pH / ORP tester features a replenishable junction, a dual-level LCD, battery life percentage indication, a stability indicator and a floating, waterproof body. The Hanna Instruments HI 98121 pH / ORP tester measures ORP up to to ±1000 mV, pH from -2.00 to 16.00 pH and temperature from 23° to 140°F. Factory calibrated with an accuracy of ±2 mV, ±0.05pH and ±1°F, the Hanna Instruments HI 98121 pH / ORP tester has an expected battery life of approximately 250 hours of continuous use. The meter automatically shuts off after 8 minutes of non-use.
The Hanna Instruments HI 98121 pH / ORP tester ships complete with protective cap, electrode removal tool, batteries, and instructions.
pH meters require regular calibration to perform at their optimal level. We strongly suggest purchasing calibration solutions. We offer both calibration kits and individual solutions to meet your needs.
