Product Description

• Slim Pen Design – Pocket‑size (186 × 40 × 32 mm, 131 g) for one‑hand operation in tight spaces—ideal at tanks, beakers, or field sites.

• Dual LCD Read‑out – Simultaneously shows pH and temperature* for instant cross‑checking (*temp shown via internal thermistor for ATC).

• Auto Temperature Compensation (ATC) – Built‑in sensor automatically corrects readings from 0 – 50 °C, guaranteeing reliability as ambient changes.

• One‑Touch Auto Calibration – Quick three‑point calibration (pH 7, 4, 10) eliminates manual trimming; perfect for non‑technical staff.

• Laboratory‑Level Precision – 0.01 pH resolution, ±0.02 pH intrinsic accuracy, 10¹² Ω input impedance—stable, noise‑free data.

• Low‑Power Consumption – Runs up to 200 hours on four AAA batteries; auto‑off circuitry extends battery life.

• Ready‑to‑Use Kit – Supplied with PE‑12 glass electrode, pH 7.00 & 4.00 buffer sachets, and manual—all in one box.
