Hanna Instruments has a long history of producing innovative instrumentation. We continue to use the best available technology to introduce enhancements to the measurement system to help ensure the accurate and reliable readings.
The benchtop meters are broken down into the following series:
- HI5000 with Large Color LCD and Advance Features
- edge Tablet Style Meters
- HI2000 Basic Benchtops
- Specialty Meters with Unique Features
Below are the most common portable meters.
The HI5000 Series of benchtops are the most advanced meters we offer for the electrochemistry market. These meters utilize an ARM processor to accomplish many tasks that would require additional electronics. The use of an ARM processor allows for Hanna to provide our customers with one of the most advanced meters on the market at an affordable price.
The HI5000 family has a large color LCD that can be customized to user preferences for viewing. Having a dot matrix display allows an infinite amount of information to be displayed. A contextual help button provides instant access to a help library based on the screen being viewed. The LCD is capable of showing up to two channels simultaneously. It is also possible to view real-time graphing of measurements.
The electrochemistry measurements made by the HI5000 family can be customized including stability criteria, iso potential points, custom buffer/standard groups, reference temperatures, and many other options.
Additional algorithms are built-in the meter and include USP <645> for pharmaceutical water quality analysis, BOD/OUR/SOUR calculations from dissolved oxygen measurements, and incremental methods when using an ISE.
edge Tablet Style Meters
The edge family are tablet-style meters that can be used as a benchtop, wall-mount, or portable meter. The edge meters offer many advanced features including automatic calibration and automatic temperature compensation of readings. All edge meters have a Good Laboratory Practice (GLP) mode to review calibration information include the data and time of the last calibration. The edge meters can log data and transfer data through either a USB port for a flash drive or a micro-USB port when connected to a computer.
For pH measurement, the edge meters offer CAL Check. The CAL Check feature identifies potential problems during the calibration process, such as clean the electrode, check the buffer for contamination, and the overall “health” condition of the electrode. For pH the edge meters are available as a dedicated and Bluetooth version for pH only and a multiparameter version that can accept either a EC or DO probe.
For EC measurement, the edge meters offer automatic temperature compensation and range selection. The edge meters are also able to measure TDS and salinity. The edge user can set the EC to TDS conversion factor, temperature coefficient, and type of salinity to be measured. For EC, the edge meters are available in a dedicated version for EC/TDS only or a multiparameter version that can accept either a pH or DO probe.
For DO measurement, the edge meters offer automatic temperature compensation and manual selection for altitude and salinity compensation. For dissolved oxygen, the edge meters are available as a dedicated version for measuring only DO or a multiparameter version that can accept either a pH or EC probe.
The HI2000 Series are basic benchtop meters that have many routinely used features, including automatic calibration and automatic temperature compensation.
For pH measurement the HI2000 meters include a version with CAL Check. The CAL Check feature identifies potential problems during the calibration process. Problems include electrode cleanliness, buffer contamination, and the overall “health” condition of the electrode.
For EC measurement the HI2000 meters include a meter available that has automatic temperature compensation and range selection. The meter is also able to measure TDS and salinity
Specialty Benchtop Meters
This category includes some meters with unique features for pH measurement, including benchtops with a built-in printer, analog output to connect a recorder, and a meter specifically designed for the education market. The meters for the educational market include those with manual calibration through trimmers and a version that has a built-in stirrer.
