Introduction
HACH HQ1140 Portable Conductivity/TDS Meter, w/o electrode
Experience hassle-free conductivity and TDS water testing with the HQ1140 Portable Meter. Accurate results, wherever you are
Durable and portable, this single probe electrochemistry meter for conductivity and TDS measurement kit is designed for field use with USB data transfer capabilities.
The HQ1140 Portable Conductivity and TDS electrochemisty meter is designed to perform conductivity and total dissolved solids (TDS) analysis in both field and lab environments. This portable meter allows you to collect accurate measurements, manage data, and easily review results. With its IP67-rated ruggedness, it can withstand field use.
The HQ portable line of electrochemistry meters provides a truly rugged, field-ready solution with on-screen step-by-step operating, calibration and troubleshooting instructions that give users confidence in their results. Unlike other field meters with basic user interfaces and less accessible data management, HQ meters secure, simplify, and accelerate the entire measurement process from calibration to data entry for field users.
The HQ Series of meters offers varying features to meet different needs. The HQ4000 Series offers three multiparameter probe inputs and larger, color displays. The HQ2000 Series offers two multiparameter probe inputs, and the HQ1000 Series offers a single probe input. These meters provide a range of measurement versatility, eliminating the need for multiple instruments.
Applications:
Groundwater | Influent for Wastewater | Municipal Water | Primary Treatment | Secondary Treatment | Surface Water
Benefits
Performing a successful calibration has never been so simple
Most measuring issues are due to incorrect calibration procedures. With our illustrated, step-by-step on-screen calibration and troubleshooting procedures, water quality professionals can succeed every time.
Deliver your daily activity in just a few clicks
Whether you are at your facility or working in the field, the Hach® HQ Series portable meter ensures your data will be safely transferred via USB.
Sensors designed for every application
We offer standard laboratory and rugged field IntelliCALⓇ smart sensors available with the HQ Series to measure a wide variety of parameters including Total Dissolved Solids (TDS), Optical Dissolved Oxygen (DO), Biochemical Oxygen Demand (BOD), Temperature, Conductivity, and pH. IntelliCAL smart probes are automatically recognized by HQ meters, retain calibration history and method settings to minimize errors and setup time. They incorporate proven technology to deliver superior accuracy and response times – even when measuring challenging samples or challenging operating environments.
