Precision Measurement for Water Quality

The TDS-3 Digital TDS Meter instantly determines the concentration of total dissolved solids in drinking water, laboratory samples, hydroponics, pools, and aquariums. Its stainless steel electrode ensures accurate readings up to 9990 ppm, making it reliable for a range of applications where water purity indicates safety or system performance. The splash-resistant design and digital LCD display provide both durability and ease of use.

Simple Calibration and Fast Response

Factory-calibrated for convenience, the Digital TDS Meter also allows user calibration to maintain measurement accuracy over time. With a lightning-fast response time of less than 2 seconds, users can quickly check water quality and make critical decisions on the spot. Its auto-off and hold functions help save battery and optimize field usage.

Robust and Versatile Construction

Crafted from durable ABS plastic, this handheld meter can withstand frequent use in diverse humidity (80% RH) and temperature (050C) conditions. The smart storage guidancekeep dry and out of sunlightensures longevity. Lightweight and portable, it fits into any toolkit for distributors, exporters, suppliers, and traders managing water treatment in India and internationally.

FAQs of Digital TDS Meter:

Q: How does the Digital TDS Meter measure total dissolved solids in water?

A: The Digital TDS Meter uses a stainless steel sensor to assess the electrical conductivity of water, which is then translated into a TDS reading (in ppm) displayed on the LCD screen. This process indicates the concentration of dissolved substances such as minerals and salts.

Q: What types of water samples can I test with this TDS Meter?

A: You can use this meter for a wide range of water samples, including drinking water, aquarium water, hydroponic systems, swimming pools, and laboratory samples. Its broad measurement range ensures suitability for various water quality applications.

Q: When should I perform user calibration, and how is it done?

A: User calibration is recommended if you suspect measurement drift or after extended use. To calibrate, use a standard solution with a known TDS value, follow the meters instructions to adjust settings until your readings match the standard. Factory calibration is set for general use out of the box.

Q: Where should I store the Digital TDS Meter to ensure longevity?

A: Store the meter in a dry place away from direct sunlight and moisture. Proper storage maintains the accuracy and durability of both the ABS plastic body and internal sensor components.

Q: What is the process for measuring water TDS levels with this device?

A: Rinse and dip the stainless steel electrode into the sample water (within 0.20.6 MPa pressure and 050C temperature range). Wait for the reading to stabilize (under 2 seconds), then observe the digital LCD result. Use the hold function to keep the reading displayed, if needed.

Q: What are the benefits of using the TDS-3 Digital TDS Meter?

A: This device provides rapid and accurate TDS measurements, can be calibrated for specific needs, and includes features like auto-off and low battery indicator. Its handheld design, splash resistance, and broad sample compatibility make it ideal for professionals and enthusiasts monitoring water quality.

Q: How can I maximize battery life and ensure accurate readings?

A: Utilize the auto-off function, avoid prolonged exposure to water, and replace the 2 x 1.5V LR44 button cells when the low battery indicator activates. Regular storage in a dry place and timely calibration also help maintain optimal meter performance.
