Temperature Tester HI98127 pHep 4 pH
Hanna’s Temperature Tester HI98127 pHep 4 pH waterproof tester is an advanced meter that incorporates many features found in portable and benchtop meters. This ergonomic device measures pH from -2.0 to 16.0 with an accuracy of ±0.1 pH. The pHep®4 includes automatic one or two-point calibration and automatic temperature compensation. Its large multi-level LCD display shows both pH and
The pHep®4 is a waterproof pH tester with a 0.1 pH resolution and an accuracy of ±0.1 pH. It offers advanced features typically found in more expensive portable instruments. One or two-point calibration is automatic, with two selectable buffer sets (4.01, 7.01, and 10.01 or 4.01, 6.86, and 9.18). The pHep®4 includes a replaceable electrode with a stainless steel round connector, eliminating the need for pin alignment or potential breakage.
The HI73127 replacement pH electrode features an extractable cloth junction, allowing for easy junction renewal. By pulling on the junction, approximately ⅛” of the junction is extracted, exposing a new portion and clearing any clogging, thus extending the electrode’s life.
Features at a Glance:
- Waterproof: Designed to float if accidentally dropped in a tank
- Expanded pH Range: -2.0 to 16.0 pH
- Automatic Temperature Compensation: Readings are temperature compensated; temperature is displayed in °C or °F along with pH reading
- Stability Indicator: Displays a clock tag that disappears when the reading is stable
- HOLD Button: Freezes reading on the display for measurement recording
- BEPS (Battery Error Prevention System): Meter automatically shuts off if there is insufficient power for an accurate measurement
- Auto-off: Meter automatically shuts off after 8 minutes of non-use to preserve battery life
