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

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
