Ultimate Discount Aquatics pH Meters & Calibration Fluids

Trans Instruments pH Meter
Superb hand held pH meter designed for hydroponic plant growing. This means that the unit operates superbly in our "dirty" aquarium water and will tolerate high levels of dissolved salts which can confuse units designed for clean/laboratory water.

Measures from 0 to 14.0 pH in 0.1 pH unit steps

Easy push-button calibration (no screw driver required) at pH 7, 4, or 10 (pH7 buffer supplied)

Auto lock function detects when a steady reading is obtained

Auto shut down after 15 minutes if you forget to turn it off

pH Calibration Fluid pH 7.01

Comes in single-use plastic envelope packets, and they are extremely accurate and field portable. Each packet contains enough fluid for a complete calibration (about 20 ml) and is intended to be discarded after use.
