Hanna Instruments has pioneered the development of portable meters. We introduced the first portable conductivity meter in 1980, which featured a four-electrode design for conducting various measurements. The first microprocessor-based portable was launched in 1984, which improved calibration. In 1990, we introduced the industry standard waterproof portable meter. Our commitment to advancing technology remains unwavering as we continue to enhance measurement accuracy.
Our company offers a wide range of professional-grade portable meters that is durable, rugged, and is designed to deliver accurate pH and ORP readings. Our selection includes waterproof meters that have an ergonomic, one-handed design, making them perfect for use on the go. We offer models with compact sizes that save space while maintaining top-quality performance. Our meters are user-friendly, equipped with integrated help features, ensuring ease of use for all. Moreover, our extended battery life will always make sure that your portable meter is ready whenever you need it. Trust our brand for reliable and precise pH and ORP measurements, wherever your work takes you.
Portable pH/ISE meters are available in multiple designs and features. The portables include versions with BNC connectors for ISEs and are available with direct concentration readout or those that use the mV scale. The portable with direct ion concentration readout features:
Portable EC/TDS/Salinity meters are available in multiple designs and features.
The following portable meters use the potentiometric (four ring) version of probes. This technology allows for a wide range of measurement using a single probe. Portable meters available include versions with manual calibration and manual selection of ranges and versions with automatic calibration and automatic range selection. Portables are available with multiple measuring modes including EC, TDS, salinity, and resistivity. Meters include both those with automatic calibration and others with manual calibration using trimmers.
Dissolved oxygen portable meters are available with either Clark-Type Polarograhic, Galvanic and Optical technologies. Each has their benefits with regards to measurement and maintenance. Portable DO meters are available with automatic or manual calibration, automatic or manual input altitude (barometric pressure) compensation and manual input of salinity for compensation. Meters are available with built-in BOD algorithm for calculating the BOD after two measurements, taken 5 days apart, are made.
Multiparameter portable meters have the ability to measure multiple parameters including pH, ORP, dissolved oxygen, conductivity, turbidity, temperature, pressure, and specific ions with the use of either chloride, ammonium or nitrate ISE.
The multiparameter meters can be broken down into three main categories.
Many meters that measure conductivity allow other units to be displayed including Total Dissolved Solids (TDS), resistivity, and salinity.
The following portable meters use an amperometric (two-electrode) technology to measure conductivity. With this technology the ranges are limited to either a low or high range version. A variety of pH/EC portable meters are available including application specific versions for water treatment, agriculture, and hydroponics. Also included in this category is a portable with a pH/ORP probe.
