The Hanna water proof pH meters measure pH and temperature and is ideal for plating baths, wastewater, swimming pool and spa water quality and environmental applications.
The HI-991001 pH meter is supplied with an HI-1296D pH/temperature probe which has an easy to clean recessed tip that prevents solids in solutions from collecting on the sensor. The stainless steel and titanium body of these probes function as a potential matching pin for increased stability of readings and extended sensor life.
the HI-991002 pH meter features a probe which can also measure Redox/ORP HI-1297D and incldues all the features of the HI1296D
This compact instrument fits in the palm of your hand and the bottom probe connection ensures the electrode cable doesn't get in your way.

Making sure you have the right electrode and meter for your application can be confusing, not to mention correct maintenance and what to do if you are having issues. You can find links to our support guides below to help you through the process.
If you are after an electrode selector guide for some of our most popular electrodes and what applications they are recommended for you can find that below.
An introduction to pH
pH, put simply is a measure of how acidic or basic a solution is. It is a measure of H+ions present.
pH can be measured in a number of ways including test strips, indicator solution or with a pH meter and electrode. If you want to read more about the pH and the pros and cons of these methods, you can check out our introduction guide here.
How to take a pH reading and care for your electrode
pH electrodes require the correct storage and regular calibration.
If you have a pH meter or are looking to purchase and need to find out more about the care and maintenance process then you can read our guide here. We also include a troubleshoot sections with the most reported issues and possible solutions.
Selecting the right electrode and meter for your application
So you have decided you need to purchase a pH meter with electrode, but with such a wide selection out there, how do you know which is right for you?
You can read our guide on the differences between electrodes and what applications different features are good for. We also have an electrode selection guide for some of our most popular electrodes.
If you require any further assistance, or extra information you can request that here and one of our trained technical specialists will be in contact. Please provide as much detail as possible so that we can get back to you with the right information.
Have you considered your servicing requirements? Much like a car, scientific instruments may need a bit of care to keep them working reliably and at their most accurate.
The Camlab Service Department have over 60 years experience in scientific instrumentation. We have a number of highly qualified internal and field-based service engineers able to perform a variety of jobs including preventative maintenance servicing and calibration.
Camlab can offer yearly service contracts which include two main types of preventative maintenance/calibration services – the back to base service and an engineer visit to your site. These options are can be offered with differing turn around times depending on the instrument type and your requirements along with loan instruments if available.
A typical preventative maintenance service includes the following:
Inspection and testing of the unit
Dismantling, cleaning and inspection of the key parts
Correction of minor defects including adjustments if necessary
Reassembly and testing
Take post adjustment / cleaning readings
Supply of calibration certificate
Return of the item to you (back to base services)
