5-in-1 Digital Water Tester TDS Meter Auto Calibration for Pool & Aquarium | Portable Water Quality Testing Pen with EC pH Salinity Temperature and TDS Meter for Drinking Water, Fish Tank, Hydroponics

Features

• High-Precision Multi-Parameter Testing: Equipped with an advanced RAM-integrated chipset, this water tester accurately measures pH, TDS, EC, salinity, and temperature. It detects subtle H+ ion changes for reliable pH readings and offers accuracy as fine as 0.05pH, 2%F.S (TDS), and 0.1.
• Durable & Reliable Probe: Features a corrosion-resistant aluminum alloy probe that ensures fast response within 3 seconds, high conductivity, and long-term reliability, with a wide measurement range: salinity (0.01%-25.00%), pH (0.01-14.00pH), TDS (0-9999ppm/10.1-200.0ppt), EC (0-9999S/cm), and temp (0-60 )
• Automatic Temperature Compensation (ATC): Minimizes measurement errors caused by ambient temperature fluctuations with built-in ATC technology, delivering consistently accurate readings across a range of environments from 0.160.0C.
• User-Friendly Operation & Auto Power-Off: Choose from PPM, PPT, or percentage readings to easily measure salt content. The meter is capable of testing salt levels in swimming pools (0-9999 ppm), seawater (10-200 ppt), and food (0.01-25%), eliminating complex calculations for users. The pen can remember your last used mode and automatically shuts off after 5 minutes of inactivity to save battery. The backlit screen clearly displays data, temperature, and battery status.
• Versatile Applications & Portable Design: Ideal for drinking water quality testing, swimming pool monitoring, aquarium maintenance, spa and hot tub management, hydroponics, and even brewing and more. Compact, lightweight, and it comes with batteries and a clear manualperfect for lab, field, or home use.
