Apera EC20 Pocket Conductivity Tester Kit | BPB Sensor, ATC, IP67
Apera Instruments EC20 — Value Series Pocket Conductivity Tester Kit
The Apera EC20 is the most reliable entry-level conductivity (EC) tester for everyday water quality testing. Powered by a proprietary BPB (Brush-Resistant Platinum Black) sensor , it delivers wider range, higher accuracy, and easier cleaning than traditional stainless steel electrodes — at an unbeatable value. Perfect for hydroponics, pools & spas, tap water, drinking water, and water treatment .
Key Features
BPB Platinum Black Sensor — Minimizes electrode polarization, expands measuring range, and increases electrode firmness for superior accuracy vs. stainless steel; easy to clean
Wide EC Range — 0–20.00 mS/cm across three auto-switching sub-ranges (0–199.9 µS/cm, 200–1999 µS/cm, 2.00–19.99 mS/cm)
2-Point Auto Calibration — Auto buffer recognition; calibration confirmation displayed on screen
Auto Temperature Compensation (ATC) — 0–50°C (32–122°F) for consistent accuracy across environments
180° Viewing Angle LCD — Dual display of EC + temperature; smiley face stable reading indicator
IP67 Waterproof & Floatable — Dustproof and drop-safe in water
1000-Hour Battery Life — 4× AAA batteries with low-battery warning and 8-min auto power-off
Self-Diagnosis — Out-of-range, low battery, and incorrect calibration alerts
Complete Kit — Calibration solutions, AAA batteries, lanyard, and portable carrying case included
