Product Description 

The ShopwithSIA Health & Home Series presents the Digital TDS Meter—the most reliable way to monitor water safety in Pakistan.

Key Features & Benefits:

• 3-in-1 Professional Testing: Why buy three different tools? This pen measures TDS (purity), EC (conductivity for plants/industrial use), and Temperature simultaneously, giving you a complete profile of your water.

• Extreme Accuracy (±2%): Don't rely on cheap strips. This digital sensor provides highly accurate readings from 0 to 9990 ppm, making it ideal for checking if your RO membranes need replacing or if your tap water is safe for infants.

• "Hold" & Auto-Off Features: Stuck in a tight spot under the sink? Press the Hold button to lock the reading on the screen so you can read it after removing the pen from the water. The auto-off feature ensures your battery stays fresh.  

• Temperature Compensation: Water temperature affects purity readings. This device automatically adjusts its calculations based on the water's temperature (0°C – 99°C) to provide the most precise PPM data.  

• Compact & Portable Design: Roughly the size of a highlighter, it fits easily in your pocket or tool kit. Perfect for field inspections, traveling to areas with questionable water, or monitoring your office dispenser.

• Broad Application: Essential for Hydroponics (nutrient levels), Aquariums (fish health), Swimming Pools (chemical balance), and Food Preparation (fruit/vegetable washing).
