Multi-Functional
Measures pH, temperature, and ORP (when ORP electrode is attached).
Replaceable Probe & Easy Calibration
High-resolution 0.01 pH measurement. Includes 2-point manual calibration using standard buffer solutions.
Dual Temperature Probes
Measures water and meat temperatures with needle-type electrode, range: 0°C to 100°C.
LCD Display with Backlight
Bright screen with backlight toggle, low battery indicator, and easy-to-read results.
Wide Applications
Ideal for laboratories, aquariums, pools, hydroponics, greenhouses, spas, and more.
Certified for Safety & Precision
CE, FCC, and RoHS certified for environmental and measurement reliability.

Do not use the pH electrode to measure ORP values.
ORP measurements require a separate ORP electrode.
Use the selector switch to choose between pH or ORP modes depending on the connected probe.
