The pH1000A benchtop pH meter is an economical, accurate and easy-to-use solution for basic, routine pH or mV measurements in the lab. The AUTOLOCK feature locks stable measurements on the display, resulting in precise, repeatable, and error-free measurements. Simple calibration procedures, automatic buffer recognition, and electrode efficiency display makes calibration quick and easy.

The following pH1000A purchase options are available:

• 601100: pH1000A instrument only
• 601104: pH1000A instrument and electrode stand
• 601305: pH1000A instrument, 1102 pH/ATC probe with built-in temperature sensor, and electrode stand
• 601306: pH1000A instrument and 1102 pH/ATC probe with built-in temperature sensor

Features of the pH1000A include:

• Measures pH, mV (ORP), and temperature
• Large, high-contrast, LCD display
• Simple 1, 2, or 3 point calibration
• AUTOLOCK mode holds stable readings on the display
• Accepts U.S. (7.00, 4.01, 10.01) or NIST (6.86, 4.00, 9.18) buffer sets
• Automatic or manual temperature compensation of all pH measurements
• Calibration is stored in memory; view electrode efficiency at any time
• BNC input allows for any pH or ORP electrode with BNC to be connected*
• Battery or AC power

* If not using the 1102 pH electrode with a built-in temperature sensor, the 1103 temperature sensor will need to be used for automatic temperature compensation.
