HI98127-00
pH Testers
- Hanna instruments - pHep4 HI98127 - pHep5 HI98128
- It shows both pH and temperature readings simultaneously, while a stability indicator is displayed to alert the user when a stable reading has been obtained
The pHep’s ease-of-use in combination with its affordability made it possible for non-technical and technical personnel alike to measure pH on the spot, accurately and inexpensively throughout a variety of industries.
The pHep4 and pHep5 include features such as a dual-level LCD, battery level indicator, replaceable pH electrode cartridge, stability indicator, automatic shut-off and automatic calibration all in a floating, waterproof casing.
The pHep4 and pHep5 use the exclusive cartridge pH electrode. Electrode replacement with the stainless steel round connector means there are no pins to bend or break during replacement.
The pHep’s replaceable electrode has a pull-out cloth junction. When the cloth junction becomes dirty from routine testing, simply pull out 3 mm (1/8”) to rejuvenate the electrode.
The pHep4 and pHep5’s exposed temperature sensor provides fast response time, and its proximity to the pH electrode guarantees much more accurate temperature compensated readings.
