pHep4 pH Tester

Hanna ID: HI98127

Hanna pH hand-held meter 4 that measures pH as well as temperature. The meter automatically compensates for solution temperature for more accurate and quick readings.

pHep 4 pH Testers

  • Dual Level Display Showing pH & Temp.
  • Rugged, Floating Waterproof Casing
  • Replaceable pH Electrode Featuring an Extendable Junction

The waterproof pHep 4 pH testers have a dual-level LCD that displays pH and °C or °F. At startup, pHep performs a self check then displays the remaining battery level to assure proper working condition. These testers also feature a stability indicator and hold feature to prompt the user when to take the reading & freeze the display for easy and accurate recording. These pH/Temperature meters have a stainless steel temperature probe for faster and more precise temperature measurement and auto-compensation. 1 or 2 point calibration is made simple with automatic recognition of both standard and NIST buffer sets. We have designed the new pHep pH electrodes with an extendable reference junction and when the electrode finally is exhausted simply insert a new electrode cartridge!

pH/EC/TDS/Temp Meter with F.S.T. Technology

  • New Technology to Check the Status of the Electrode
  • Measures a Variety of Parameters with One Instrument
  • Fast Response Probe

HANNA instruments® developed new F.S.T. technology for the new HI 9813-6. With this special security system, if the meter encounters incorrect readings, the instrument doesn’t display values close to pH 7, but close to pH 4, making the problem clear. To allow maximum confidence in your measurements, the meter is equipped with two LEDs and a Check button. When pressing this button, after immersing the electrode in the proper solution, HI 50021P (Cal-Check solution), one of the LED’s will light up to indicate the status of the meter. The green LED (OK) indicates the probe is working correctly, while the red LED (C&C Clean & Cal) indicates the electrode needs attention.

HI 9813-6 is supplied complete with pH/EC/TDS/T HI 1285-6 probe with 1 m cable, pH 7, 1.41 mS/cm and 1500 ppm calibration solution (20 mL each), cleaning solution 2 pcs), HI 50021 test solution (2 pcs), blue protective case, battery and instructions.
