Water-Resistant pH/mV/ Temperature Meter Kit

• Three Meters in One
• Water-Resistant, Rugged Case
• Dual LCD Display
• 5 Memorized Buffer Values for Fast, Accurate Calibration
• Perform a One or Two Point Calibration for Greater Accuracy


The PHH-25 is a versatile pH/mV/°C meter which displays pH, millivolts and temperature (°C). The meter has a water-resistant ABS case. The rugged housing and battery power make it ideal for field or industrial plant use.

To ensure proper calibration, the Auto-Instruction feature guides the user step-by-step through calibration using graphic symbols. In addition, the meter displays a READY symbol when the electrode has stabilized in the buffer. A large dual-level LCD displays pH/mV and temperature at the same time.

The PHH-25 has five memorized buffer values for fast, convenient and accurate calibration. In addition to the conventional 4.01, 7.01 and 10.01 buffers, the PHH-25 allows calibration at the NIST values of 6.86 and 9.18. Users can perform a one-point calibration at any of these values, or, for even greater accuracy, a two-point calibration using any of the remaining buffer values.

The meter is supplied as a complete kit, including pH electrode temperature probe, pH 4 and pH 7 buffers and rugged hard plastic carrying case.
