Electrochemical Measurements
The CA 10101 portable pH-meter from CHAUVIN ARNOUX is ideal for mobile applications: in the field, in the laboratory or in production. It can be used for quick, accurate, professional measurements of pH, Redox potential and temperature.

Earth and resistivity clamps
The C.A 6416 earth clamps, delivered in a carrying case, are ideal for quick earth-loop resistance measurements. 600V CAT IV, they display the earth voltage with a dangerous voltage alarm and provide additional safety during measurement.
They are particularly easy to use thanks to ergonomic innovations such as a force compensation system to keep the clamp open without any effort and an OLED display, offering visibility over an angle of 180° whatever the lighting conditions.
The automatic PRE-HOLD function when the clamp is opened and the automatic jaw calibration function at power-up help to optimize processing of the measurements provided by the clamps.

Power, energy and disturbance analysers
Designed for test and maintenance departments working in industrial or administrative buildings, the Qualistar+ C.A 8331 can be used to obtain a snapshot of the main features characterizing the quality of the electrical network.
Easy to handle and particularly compact, this instrument also offers a large number of calculated values and several processing functions. The C.A 8331 is equipped with 3 voltage measurement channels and 3 current measurement channels.
When the current sensors are connected to the C.A 8331, it recognizes them automatically. It also offers the possibility of mixing different types of current sensors and configuration of the ratios allows direct reading of the measurements.
It is ergonomic, lightweight and compact.Its wide LCD screen comprising 2 digital displays is particularly easy to read. It includes indications intended to facilitate implementation and interpretation of the measurements. The automatic measurement mode allows measurement to be triggered without pressing a button.
An automatic recording mode is also available.
