pHep pH Meters

The waterproof pHep® 4 and pHep® 5 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 and 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.

  • pHep® 4 (HI 98127) has the most common pH range of 0.0 - 14.0 pH
     
  • pHep® 5 (HI 98128) has a more precise pH range of 0.00 - 14.00 pH

All pH meters require calibration to provide accurate results.

If you do not already have buffer solutions available for calibration, we recommend our 25304 buffer sachets.

This product includes ten 20mL ready-to-use buffer packets, five each of pH 4 and pH 7 buffers.

We also recommend purchasing our 25310 electrode storage solution to protect the electrode when not in use.
