Product Overview: TDSTestr 11+ Waterproof TDS Tester:
The Eutech TDSTestr 11+ is an advanced, waterproof, multi-range Total Dissolved Solids (TDS) pocket tester engineered to deliver high accuracy and maximum value. This instrument is designed to reliably measure a wide spectrum of dissolved solids, making it suitable for applications ranging from pure water testing to wastewater analysis. The TDSTestr 11+ retains essential Eutech features like Automatic Temperature Compensation (ATC) and an adjustable TDS factor, ensuring accurate and reliable readings across a broad TDS range.
Key Features and Enhanced Performance:
Multi-Range Measurement Capability:
The TDSTestr 11+ offers multi-range testing capabilities, measuring up to three ranges: 0 to 200.0 ppm, 0 to 2000 ppm, and 0 to 10.00 ppt. All models are equipped with selectable or auto-ranging options, providing direct readouts for easy, on-the-go testing.
Innovative Sensor Design:
This model features a unique cup-style sensor, which is perfect for micro sample measurements. The innovative sensor housing design allows it to be used in both dip-style and cup-style configurations for holding small volumes of samples. The sensor is built for superior chemical durability, featuring a VALOX® sensor casing and an industrial grade SS316 stainless steel sensor element that protects against harsh samples.
User-Friendly Operation and Display:
The tester boasts a large, easy-to-read custom dual display screen, which provides clear readouts of the measurement mode, ATC status, battery level, temperature, and other diagnostics. The user-friendly 'hold' function allows measurements to be frozen for delayed recording purposes.
Durability and Cost Efficiency:
Built with a rugged, anti-roll ribbed design for a firm grip, the TDSTestr 11+ features an IP67 waterproof housing that keeps the tester functional even under wet conditions. If accidentally dropped into water, the unit floats for easy retrieval. The tester body is reusable, and sensors are user-replaceable via a convenient screw cap design, contributing to lower operating costs in the long run.
Advanced Power Management:
The instrument is designed with advanced power management, ensuring the micro alkaline batteries last for more than 150 hours. An automatic shut-off feature further conserves battery life, engaging 8.5 minutes after the last key press.
Calibration and Accuracy:
The TDSTestr 11+ achieves a high accuracy of ±1% Full Scale. It features:
• Adjustable TDS Factor: Users can select the appropriate TDS factor from 0.40 to 1.00, which helps distinguish various salt measurements and provides more accurate results.
• Multi-Point Calibration: The TDSTestr 11+ supports 3 manual calibration points (one per range), allowing users to customize settings according to specific measurement needs. Single-point calibration is also available for basic testing requirements.
• Automatic Temperature Compensation (ATC): ATC operates across a range of 0 to 50 °C.
Applications:
The TDSTestr 11+ is suitable for a diverse range of water quality monitoring and analysis applications, including:
• Water and wastewater treatment
• Boiler blow-down
• Electroplating rinse tanks
• Drinking water analysis
• Hydroponics
• Printing industry
• Aquaculture, aquariums, and fish farms
• Swimming pools and spas
