Description

A microprocessor-based pH/mV/Temperature Meter offers precise measurement and advanced control features. Here are the key features typically found in such instruments:
Microprocessor Features
High Accuracy & Precision
Digital signal processing ensures accurate readings for pH, mV (ORP/Redox), and temperature.
Multi-Parameter Display
Simultaneously displays pH, mV, and temperature on a large backlit LCD or LED screen.
Automatic Temperature Compensation (ATC)
Built-in temperature sensor or probe automatically adjusts pH readings for temperature fluctuations.
Auto Buffer Recognition
Recognizes standard buffer solutions (e.g., pH 4.01, 7.00, 10.01) during calibration, reducing user error.
3-Point or Multi-Point Calibration
Ensures high accuracy across the full pH range.
Data Logging and Storage
Stores multiple readings for later review or export (some models store 100–1000+ data sets).
USB/RS232 Output or Bluetooth Connectivity
For PC interface or data transfer to software for analysis/reporting.
Electrode Status Indicator
Alerts user to cleaning or replacement needs for the pH electrode.
Measurement Range
pH: typically 0.00 to 14.00
mV: ±1999 mV
Temp: 0°C to 100°C (or more depending on model)
Automatic / Manual Calibration Options
User-friendly operation with either manual fine-tuning or fully automatic modes.
Battery Backup / Power Failure Memory
Retains settings and data during power loss.
GLP Compliance (Good Laboratory Practice)
Stores calibration history, time, and date for audit trails.
Password Protection
Restricts access to calibration or configuration settings for quality assurance.
Compact & Portable Design (for handheld models)
Useful for fieldwork or portable lab use.
