Sper Scientific 850055 Advanced pH Meter: Precision & Performance for Critical Measurements

The Sper Scientific 850055 Advanced pH Meter is a robust and versatile instrument designed for professionals demanding high accuracy and detailed analysis in laboratory and field settings. This meter provides instantaneous and precise readings, combining essential parameters with advanced data management capabilities.

Key Features & Benefits:

• Simultaneous Multi-Parameter Display: View pH (with 0.01 resolution) or mV readings in large, easy-to-read digits, alongside time, date, and temperature (in °C or °F) on the lower display. This allows for comprehensive monitoring at a glance, eliminating the need to switch between screens.
• Intelligent Feedback: The meter actively indicates stable readings, ensuring you capture data only when optimal conditions are met. It also features a low battery indicator and the ability to display stored calibration data for quality assurance and compliance.
• Robust Data Logging & Review: Effortlessly scroll through up to 99 data points directly on the backlit LCD. Each point is time-stamped and includes min/max readings, providing a convenient way to track trends and significant changes without needing external software. The backlight ensures readability in any lighting condition.
• Advanced Calibration & Compensation:
  • 5-Point Calibration: Achieve exceptional accuracy across the entire pH range with up to 5-point calibration, crucial for applications requiring stringent measurement precision.
  • N.I.S.T. Buffer Recognition: This feature simplifies calibration by automatically recognizing standard N.I.S.T. pH buffers, ensuring adherence to recognized measurement standards.
  • Automatic or Manual Temperature Compensation (ATC): pH is temperature-dependent. The meter offers both automatic (with a compatible probe) and manual temperature compensation to deliver accurate pH results regardless of sample temperature fluctuations.
• Data Management & Connectivity: The integrated USB port allows for seamless data streaming to a computer. To unlock this capability, the USB Cable 840054 and Data Acquisition Software 840052 are required (sold separately). This enables comprehensive data analysis, storage, and report generation.
• Versatile Probe Compatibility: Equipped with a standard BNC connector, the meter is compatible with a wide range of pH or ORP (Oxidation-Reduction Potential) probes, offering flexibility for various applications. Please note: PROBE NOT INCLUDED with meter-only purchase.
• Power Options: Operates on 4 AAA batteries (included) for portability, or use the optional AC Adapter #840027 for extended benchtop use.
