Refrigerator Thermometer
A simple thermometer that hangs or stands inside a fridge.
Why we picked it
The fridge dial is a setting; this shows the temperature your items actually sit at.
Measuring & Tracking
Digital pH Meter
A handheld probe meter that shows pH as a number.
What it is
A handheld meter with a probe that shows pH as a number on a screen.
What it solves
Strips give you a colour band. A calibrated meter gives you a value you can write down and repeat.
What this kind of product gives you
- A numeric reading instead of a colour match
- Calibrates against buffer solutions
- Many models correct automatically for temperature
Who it is for
Anyone who needs a recorded, repeatable number.
Why we picked it
When a strip is not precise enough, a calibrated meter gives a value you can record.
What to check before you buy
- Whether calibration buffers are included or bought separately
- Whether the probe can be replaced when it wears out
- Automatic temperature compensation, if your samples are not at room temperature
- The probe must be stored moist in storage solution, never dry
