Upgraded TDS Meter Digital Water Tester One Alone Overview A compact professional handheld digital water tester that combines multiple measurements in one unit. Designed to provide fast, clear readings for pH, TDS, temperature, specific gravity S.G, ORP, and resistivity for routine water analysis and process checks. Key benefits Multiparameter testing in one device: eliminates the need for multiple tools by measuring pH TDS TEMP S.G ORP and resistivity with a single handheld meter. Faster decisions: instant digital readout helps you detect changes and adjust treatment or dosing without delay. Practical for field and bench use: compact portable design for onsite checks and routine monitoring. Professional grade convenience: simplifies workflows for hobbyists and technicians who need reliable, repeatable measurements. What it does pH measurement: monitors acidity and alkalinity for water treatment and process control. TDS measurement: estimates total dissolved solids to evaluate water purity and filtration performance. Temperature measurement: compensates readings and documents conditions during testing. Specific gravity S.G measurement: aids applications where density tracking is required. ORP measurement: indicates oxidation reduction potential for disinfection and process monitoring. Resistivity/fertile resistivity testing: assesses electrical resistance of water or nutrient solutions for process control. Features and attributes Functions: PH, TDS, TEMP, S.G, ORP, Resistivity. User interface: digital display provides direct numeric readings for each parameter. Form factor: compact handheld meter suitable for portable and bench use. Construction: designed for regular use in workshop greenhouse and lab environments. Compatibility: suitable for a range of water types and applications including tap water well water filtered water nutrient solutions and process water. Performance notes Designed for quick readouts to support frequent spot checks and troubleshooting. Multiparameter capability reduces the time and expense of using separate instruments. Compact size and straightforward operation make it well suited for operators with basic technical training. Use scenarios Hydroponics and greenhouse nutrient management: monitor pH TDS and resistivity to track nutrient solution strength and maintain consistent delivery to crops. Aquarium and aquaculture maintenance: measure pH TDS temperature and ORP to monitor water quality and support stable conditions for aquatic life. Water filtration and equipment checks: verify TDS and resistivity before and after filtration systems or when commissioning pumps and treatment units. What you get A single upgraded digital water tester One Alone that combines essential water quality measurements in one portable instrument for routine testing and process monitoring. Notes Intended for measurement and monitoring purposes in hobby commercial and light industrial settings. Follow standard calibration and maintenance procedures to maintain accuracy.
