This is a waterproof pH tester with a 0.1 pH resolution and an accuracy of ±0.1 pH. It has many advanced features that are found in more expensive portable instrumentation. One or two-point calibration is automatic to two selectable buffer sets (4.01, 7.01, and 10.01 or 4.01, 6.86, and 9.18). Also features a replaceable electrode with a stainless steel round connector. This cartridge design has no pins to line up or that can break.

Features

• Waterproof: designed to float if accidentally dropped in a tank
• Replaceable pH electrode
• Automatic two-point pH calibration
• Expanded pH range is from -2.0 to 16.0 pH
• All readings are compensated for variations in temperature
• Meter displays a clock tag that will disappear when the reading has achieved stability
• HOLD button: freezes reading on the display to allow recording of measurement
• BEPS (battery error preventative system)
• Auto-off: meter automatically shuts off after 8 minutes of non-use to maximize battery life

• Using an old or expired electrode

Five Tips for Calibrating your pH Meter

• 1. Always read your manual
• 2. Make sure you have the right pH buffers
• 3. Calibrate often
• 4. Be aware of your slope and offset
• 5. Electrode care
