Product Description

• Purpose‑Built for Soil Testing – Measures soil pH on the spot with a rugged epoxy‑coated spear‑tip electrode that penetrates compact media without damage.

• Accurate, Repeatable Readings – 0 – 14 pH range, 0.01 pH resolution, and ±0.07 pH accuracy in the critical pH 5‑9 band safeguard fertiliser efficiency and crop health.

• External Two‑Point Calibration – Manual slope (pH 4) and zero (pH 7) adjustments let you fine‑tune accuracy for varying field conditions.

• Large, Splash‑Proof LCD – 13 mm digits on a sealed front panel stay legible and protected during outdoor work.

• Fast Response, Low Power – 0.4 s sampling and only 2 mA current draw; one 9 V battery powers long field campaigns.

• Portable & Lightweight – Pocket‑sized (135 × 60 × 33 mm) and just 196 g, including battery—easy to carry between test plots or greenhouses.

• Ready‑to‑Go Kit – Supplied with soil pH electrode, pH 4.0 & 7.0 buffers, hard case, and manual—no extra accessories required to start measuring.
