The versatile analyzer PCE-PHD 1 is ideally suited for the quick determination of different chemical parameters of water and materials containing water. The device is equipped with many interfaces and is operated with external electrodes and standard batteries. It is therefore suitable for tests in the laboratory as well as for measurements directly in industrial production plants or in outdoor water.
With different electrodes, the compact handheld measuring instrument from PCE Instruments allows the measurement of the pH value, redox potential, conductivity, TDS value, salinity, and dissolved oxygen as well as the temperature of the sample.
On the large display with backlight, the readings are very clear even under poor lighting conditions. For later evaluation, the readings can be saved to an SD card, along with date and time. For continuous measurements, sampling rates of a second up to nearly nine hours can be selected. The saved XLS files can be opened and edited with the common PC programs.
All measurement settings can be made via the keys below the display of the handheld device. All connections at the sides of the meter are easy to access and clearly marked. The SD card slot can be found at the bottom and on the right-hand side, you can find a power connection, a reset key, and an RS232 interface. The four sockets for the different electrodes are located at the top, in one row.
The probes with the BNC connection can very easily be replaced by new ones or probes with different specifications. For pH measurements, there are special pH electrodes for lots of certain sample materials. For instance, PCE Instruments offers the following probes as optional accessories:
- pH glass probe for low-conductivity liquids such as beer or wine,
- pH glass probe for low measured volumes of blood, beer, or dairy products,
- pH glass probe with stainless steel blade for food such as cheese or meat
- pH plastic probe for waste water, shampoo, pastes, paints, and
- pH glass probe for soil and sludge.
The simple multipoint calibration ensures a high accuracy of the measurements. Furthermore, the PCE-PHD 1 has functions for manual and automatic compensation of the temperature.
The multi-parameter measuring instrument is therefore a very practical, reliable, and easy-to-use measuring device for the analysis of liquids. It is suitable for the commercial, agricultural, and industrial sector as well as for hobby applications such as aquaristics.
The PCE-PHD 1 can be ordered with a single electrode or as a set with several electrodes. The PCE-PHD-1-KIT1 with electrodes for pH, oxygen, conductivity, and temperature with calibration solutions and a carrying case is especially practical for use at different measuring sites.
