EC TEST 11 PLS / ECTestr 11+ Multi-Range Pocket Conductivity Meter
Product Overview
The Eutech EC TEST 11 PLS, also widely known as the ECTestr 11+, is a robust and highly portable conductivity meter engineered for precise water quality testing across a broad range of applications. This pen-type meter offers a multi-range capability, allowing it to accurately measure solutions spanning from pure water to highly conductive wastewater. The "PLS" (Plus) model designation signifies enhanced features, including exceptional durability and a user-friendly design. It is specifically designed to measure conductivity, resolution, and temperature.
Key Product Features
Multi-Range Measurement Capability
This single instrument provides accurate measurements across three distinct conductivity ranges, supporting selectable or auto-ranging options. This flexibility ensures reliable readings, whether testing drinking water or industrial rinse tanks. The overall measurement range extends up to 20.00 mS/cm.
Superior Durability and Water Resistance
The meter features an IP67 rated housing, ensuring it is completely waterproof and dustproof, maintaining its integrity even in wet operating environments. For enhanced handling, the design includes a unique anti-roll ribbed grip.
Innovative Sensor Design
The sensor is designed for durability and ease of maintenance. It features a user-replaceable, cup-style sensor housing, which permits both traditional dip-style measurements and measurements using the cup-style method. The sensor elements are constructed from industrial-grade SS316 stainless steel and feature a VALOX® casing, providing excellent chemical resistance and longevity. The meter utilizes a sensor cup design.
Comprehensive Display and Data Management
The large screen display provides a comprehensive view of critical measurement parameters simultaneously, including conductivity readings, temperature readings, operational mode, ATC status, and current battery level. The meter includes non-volatile memory and an Auto Power-Off function that activates 8.5 minutes after the last key press to preserve battery life.
Flexible Calibration and Compensation
The ECTestr 11+ supports both single and multi-point calibrations, offering up to 3 calibration points (selectable as automatic or manual). It is equipped with Automatic Temperature Compensation (ATC), which functions across a temperature range of 0 to 50 °C (32 to 122 ºF), using a fixed temperature coefficient of 2% per °C.
General Applications
The ECTestr 11+ is an ideal solution for general water quality testing and process control, including:
• Water and wastewater treatment
• Industrial tasks such as boiler blow-down and electroplating rinse tanks
• Agricultural applications like hydroponics
• Monitoring drinking water quality
• Aquaculture, including fish farms and aquariums
• Printing industry applications
• Checking chemical levels in swimming pools and spas
