Microprocessor pH Meters Models 1012 and 13
Microprocessor pH Meters – Models 1012 & 1013
The 1012 and 1013 series are advanced microprocessor-based benchtop pH meters designed for reliable and accurate measurements in any laboratory setting. Built on a foundation of stability and precision, both models offer a user-friendly interface, making them suitable for everything from routine analysis and education to demanding research applications.
Both instruments feature a large, backlit LCD that displays pH and temperature simultaneously, along with status indicators for calibration and measurement stability. The core microprocessor control ensures fast, stable readings and provides intelligent, guided prompts during the multi-point calibration process. Automatic Temperature Compensation (ATC) is a standard feature, guaranteeing the highest accuracy by automatically correcting for any temperature fluctuations in the sample.

The key difference lies in their advanced capabilities, allowing users to select the model that best fits their application needs.
Model 1012: The Laboratory Standard Microprocessor pH Meters Models 1012 and 13
The
Model 1012 is the ideal workhorse for routine laboratory use, quality control, and educational environments. It is focused on providing highly accurate and repeatable
pH and Temperature measurements with a simple, intuitive workflow. Its precision and reliability make it the perfect choice for users who need a dedicated, high-quality pH meter without the need for advanced data output or redox potential measurements.
Model 1013: The Advanced Analytical Meter Microprocessor pH Meters Models 1012 and 13
The
Model 1013 includes all the features of the 1012 and adds two critical functions for advanced scientific and compliance-driven applications.
- mV Measurement Mode: This adds the ability to measure millivolts (mV), making the 1013 a versatile tool for performing ORP (Oxidation-Reduction Potential) tests and for diagnosing pH electrode health.
- Data Output: It is equipped with a data port (typically RS-232) for connecting to a computer or printer. This allows for data logging, analysis, and documentation, which is essential for GLP (Good Laboratory Practice) compliance and detailed record-keeping.
