Introduction
A water pocket TDS meter is a pocket-sized instrument used to measure the total dissolved solids (TDS) of the water, which indicates the concentration of the dissolved salts and the minerals, and it is used in the water treatment, the drinking water, the hydroponics, the aquaculture, and the many other applications. The water pocket TDS meter measures the TDS by the measurement of the electrical conductivity of the water, which is related to the concentration of the dissolved ions, and it converts the conductivity to the TDS value, expressed in parts per million (ppm), with the temperature compensation; the water pocket TDS meter consists of a pocket meter with the display, a conductivity sensor or the probe, a temperature sensor, and the battery, and it is compact and portable, with features such as the calibration and the automatic temperature compensation; the water pocket TDS meter is used for the measurement of the TDS of the drinking water, the well water, the reverse osmosis water, the hydroponic solutions, and the aquarium water, for the quality control, for the monitoring, and for many other applications, and it is an essential instrument for the on-site TDS measurement. Water pocket TDS meters are used in the water treatment, in the drinking water, in the hydroponics, in the aquaculture, and for many other applications. With their pocket size, water pocket TDS meters are essential for the convenient TDS measurement.

FAQ
Q1: What testing scenarios is this instrument mainly applied to?
A: The pocket TDS meter is used in drinking water testing, aquaculture, hydroponics, aquarium maintenance, water treatment and field monitoring to quickly measure the total dissolved solids concentration in water. It supports drinking water quality assessment, reverse osmosis system performance verification, hydroponic nutrient solution management, aquarium water quality monitoring and field water quality survey. TDS measurement indicates the total concentration of dissolved inorganic salts and minerals in water, which is a simple indicator of water purity, mineral content and filtration system performance. The pocket-sized design allows convenient on-site testing for homeowners, aquarium enthusiasts, hydroponic growers, water treatment technicians and field inspectors requiring immediate TDS readings.
Q2: What standards does the instrument comply with?
A: The meter complies with relevant IEC 61010 laboratory safety standards and water quality measurement standards. TDS measurement references ISO 7888 for conductivity and applicable GB/T standards. Calibration should use certified TDS or conductivity reference solutions with a specified conversion factor.
Q3: What is the warranty period for the whole machine and key components?
A: The whole meter is covered by a 12-month warranty. The probe and meter circuit are covered, while calibration solution and batteries are consumables excluded from warranty. Probe damage from improper storage, dropping or corrosive samples is also excluded.
Q4: Is this device difficult to operate? Is professional training required?
A: Operation is simple: power on, immerse the probe and read the display. No professional training is required, but users should follow calibration procedures and proper probe handling. We provide an operation manual and remote guidance. Users should be aware that TDS meters measure conductivity and convert to TDS using a factor that may vary with water composition.
Q5: What is the typical lead-time for order delivery?
A: Standard models require 7-30 working days. In-stock units can ship within 3-7 working days. Custom configurations or large built-to-order systems may require additional time, and we confirm the exact schedule before order confirmation.
Q6: Is regular calibration required? What is the recommended calibration cycle?
A: Calibration with certified TDS or conductivity reference solution should be performed periodically, typically monthly or when readings become inaccurate. Full meter calibration is recommended every 6-12 months. Probe condition should be monitored and cleaned regularly.
Q7: Are supporting consumables universal?
A: Calibration solutions are available from chemical suppliers. TDS probes may be model-specific for some designs. Long-term consumable cost is very low for a pocket meter.
Q8: Can I customize parameters or supporting accessories?
A: Customization includes measurement range, TDS conversion factor and display units. Additional probes and calibration solutions can be ordered separately. Custom orders extend delivery lead-time.
Q9: Does the purchase include on-site installation and commissioning service?
A: No installation is required. The package includes the meter, calibration solution and instruction manual. On-site service is not included for this type of pocket instrument.
Q10: What types of samples are compatible with this equipment?
A: The meter measures TDS of aqueous solutions within the measurement range and temperature specification. Highly corrosive samples may damage the probe. Very high TDS samples may exceed the range and require dilution. Users should be aware that the TDS conversion factor is typically calibrated for sodium chloride or a specific water type, and may not be accurate for waters with significantly different mineral composition. For precise work, a conductivity meter with adjustable conversion factor is recommended.
