Description
Three meters that differ by accuracy and by what is in the box
All three share the same body — IP67, a lithium glass membrane probe, a detachable sensor shield and a backlit LCD. What separates them is how accurate they are, whether the probe can be replaced, and which calibration solutions you get. That last point is the one people miss: a meter without the right buffers is a meter you cannot trust.
Which one do I need?
- pH Meter Kit — pH and temperature to ±0.1. Fixed probe. Ships with pH 4.00 and 7.00 buffers
- pH Meter PRO Kit — pH and temperature to ±0.01, replaceable probe, high/low alarms and auto-hold. Ships with pH 4.00, 7.00 and 10.01 buffers, 3M KCL storage solution and three calibration vials
- Hydroponic Meter PRO Kit — adds EC, TDS and salinity to pH and temperature, at ±0.01. Ships with pH 4.00 and 7.00, 12.88 mS and 1413 µS conductivity solutions, 3M KCL and four calibration vials
Key Benefits
- IP67 rated — a dropped meter is a wet meter, not a dead one
- Replaceable probe on both PRO models, so the meter outlives its sensor
- Calibration solutions in the box on all three, not sold separately
- Backlit LCD for reading in a dark room
- High and low alarms with auto-hold on the PRO models

- Body: 4.2 × 17.8cm on all three
- pH accuracy: ±0.1 on the pH Meter Kit, ±0.01 on both PRO models
- Probe: lithium glass membrane; fixed on the pH Meter Kit, replaceable on the PRO models
- Hydroponic PRO TDS factor: adjustable 0.40–1.00, default 0.71
- Rating: IP67
- Supplied with: travel lanyard on all three, plus the solutions and vials listed above
