Model CP-411 -Water Proof pH-Meter

• Simple field and laboratory meter.
• Measures pH, redox potential (ORP) and temperature.
• The display enables simultaneous readout of the measured function and temperature.
• pH electrode calibration in 1 to 3 constant points (4.00, 7.00, 9.00 pH).
• Memory of 50 results.
• No PC connection.

• Large easy to read LCD display enables simultaneous readout of the measuring function and temperature value.
• Waterproof housing (IP-66) enables work in difficult conditions.
• Small size and low weight make working in the field easier.
• Two kinds of power source, battery or optional power adapter, enable working in the field or long lasting work in laboratory.
• Calibration of the pH electrode: 1, 2 or 3 points.
• Automatic buffer detection 4.00; 7.00; 9.00 pH. (optionally 4.00; 7.00; 10.00 pH).
• Automatic temperature compensation.
• Depending on the kind of connected pH electrode may be used for measurements of clean water, waste water, meat, cheese, pastes, soil etc.
• Readout of the electrode`s slope and offset.
• Possibility of automatic calculation of the redox potential result, received with the chloride/silver electrode, to the hydrogen electrode.
• Wide range of the temperature measurement.
• Easy-in-use.
• Memory of 50 results.
• Equipped with separate stainless steel temperature sensor (Pt-1000B).
• Powered by 9V battery or power adapter (12 V / 100 mA) option.
• Long-lasting work on 1 battery.
• Automatic switch off function to protect the battery.
• 24 months of warranty for the meter.

The standard set includes CT2B-121 temperature sensor with Pt-1000B resistor, EPS-1 pH electrode for measurements in clean water. It should not be used in other types of liquid. Measurements in liquids with sediments should be made with use of IJ-44A pH electrode, which enables measurements in various samples of both clean and contaminated liquids and semi-solids. Its unusual construction (”intermediate junction”) protects the real junction (diaphragma) of the electrode against clogging, ensures stable measurements in these types of liquids or semi-liquid masses, in which other electrodes stop working quickly. When properly handled and maintained, the electrode`s lifetime is longer than the standard electrodes.
