Microprocessor pH/mV/Temperature Meters with 5 Memorized pH Buffers

• Two Models to Choose From - One with RS232
• Auto-Instruction Feature for Easy Calibration
• READY Indicator for Stable Readings
• Large LCD Displays pH / mV and Temperature (°C)


The PHB-45 Series of pH meters are capable of performing a wide range of laboratory pH, mV and temperature measurements. The meters feature two mV ranges:
one broad enough to cover ORP measurements; one sensitive enough for accurate ISE measurements.

The Auto-Instruction feature guides the user through calibration using graphic symbols. The meters also display 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.

Each meter has five memorized buffer values for fast, convenient and accurate calibration. In addition to 4.01, 7.01 and 10.01 buffers, the PHB-45 allows calibration at the NIST values of 6.86 and 9.18.
Users can perform a one or two point calibration at any of these values

The PHB-45-RS232 is equipped with an RS232 port for automatic downloading to a PC. Both the PHB-45 and the PHB-45-RS232 models come standard with CSA and UL approved power socket. A 12 VDC power transformer is standard for 110 VAC power. For 220 VAC power supply, add suffix (-220VAC) to the model number at no additional charge.
