Plastic 3-in-1 combination pH electrode, electrode holder, pH standard buffer solutions (4.00/7.00/10.01 pH, 500 mL each), and 9 VAC power adapter.
The PH 550 benchtop pH meter features a microprocessor chip which provides automatic temperature compensation, data storage, parameter setup, and Max/Min reading display. The meter offers a pH range from 0 to 14 and a three-point automatic calibration, with the ability to recognize standard buffer solutions (USA or NIST series). The advanced digital processing technology improves meter response time and measuring accuracy. A stable reading display icon appears when the measuring value is stable.
The 3-in-1 combination pH electrode measures pH and temperature simultaneously. The compact meter includes a detachable electrode holder and three bottles of pH buffer solution. It has a dustproof and spillproof rating of IP54. Connectors are protected by silicone seal caps.
