Portable pH and Temperature Testers

Portable pH and Temperature Testers

The waterproof pHep® 4 and pHep® 5 pH testers easily and accurately measure pH on the spot. These waterproof pH testers have a dual-level LCD that displays pH and temperature (°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 new pH/Temperature meters have a stainless steel temperature probe for faster and more precise temperature measurement and auto-compensation.
