Lab2Go - no matter if environmental monitoring, service labs or aquaculture With its unique multi-parameter function of photometry and full electro-chemical pH- and ORP-measurement, pHotoFlex pH shows its strength with more complex tasks in like environmental monitoring e.g. for water framework guidelines, process monitoring in changing sites and for fish hatcheries and aquaculture by determining NH3 and CO2:
more than 180 programs for standard parameters
Smart adapter for wide range of test kits, vias and measurement concentrations
Versatile with special methods NH3, CO2, color
Electro-chemical pH and ORP measurement with automatic temperature compensation (ATC)
The energy-efficient LED optics with 6 wavelengths and a captive adapter for versatile applications with 16 and 28 cuvettes allows the measurement of the smallest concentrations with more than 180 programs for standard parameters and color.
With a multitude of available test kits - from lot-certified cuvettes to economic powder reagents, it is suitable for monitoring by health offices via environmental monitoring all the way to service labs. A list of favorites for the most commonly used tests, sample ID numbers and more than 3,000 measurements per battery set facilitate field measurements.
The integrated pH function is a complete electro-chemical pH measurement of pH 0-16 with automatic buffer recognition (TEC/NIST) by using the comprehensive WTW selection of pH electrodes. The temperature compensation automatically takes place in the admissible measuring ranges from -5 €¦ 100 °C. The WTW MultiCal routine allows the automatic calibration with up to 3 calibration points. For field use the maintenance-free SenTix 41 is recommended, for precision measurements in the lab, the glass electrode SenTix 81 is frequently used.
The optional PC software LSdata offers GLP-compliant data evaluation with data filter and allows the input of up to 100 user-defined programs, automatically calculate these as methods and save them to the pHotoFlex. For the convenient use in the field, there is a case set available, including the pH probe SenTix 41 as a mobile lab with work surface and storage compartment as well as a lot of accessories, such as pH standards, tripod, pipettes and replacement batteries. For lab use, the photometer can be used in conjunction with a LabStation (optional) with site-supplied power and fitted with an external barcode reader.
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.
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.
