The CMA wireless ORP sensor W30 measures the ability of a solution to act as an oxidising or reducing agent. ORP stands for oxidation-reduction potential, also known as redox potential. The sensor is equipped with an OLED colour display that shows sensor information and measured values. This makes the sensor suitable for use as a stand-alone measuring instrument.
This wireless ORP sensor can be used wirelessly via Bluetooth or wired via USB with the Coach 7 or Coach 7 lite programmes/apps on computers (Windows and Mac), Chromebooks and mobile devices (Android and iOS).
The ORP sensor consists of an amplifier and an ORP electrode that is attached to the amplifier via a BNC connector. The electrode is housed in a long plastic tube with an opening at the bottom and comes with a storage bottle containing a protective solution. When not in use, the electrode must be stored in this bottle. During measurements, the electrode must be immersed approximately 1 cm deep in the test solution.
The ORP sensor is supplied with a factory calibration in mV. When using the Coach programme, the predefined calibration can be shifted using the “Set Value” option.
Technical specifications:
-Measuring range: -450 mV .. 1100 mV
-Resolution: 0.1 mV
-Warranty: 36 months
-OLED display: 0.96" 128 x 64px
-Storage solution pH 4 KCl solution (10 g KCl in 100 ml buffer pH-4 solution)
-Maximum sample frequency: 2 Hz (Wireless, 1000 Hz with USB cable)
-ORP element: 99% pure platinum band on a glass rod
-Battery life: 8 hours when fully charged (rechargeable)
-Connection: Bluetooth 5, Low Energy (Mac, Android, iOS) Bluetooth 2.1, Classic (Windows) or USB-C 2.0
-All sensor specifications can be found in the Manual, see Downloads.
Suggestions for biology and chemistry practicals:
-Measuring water quality: Redox reactions determine the behaviour of many chemical components in drinking water, waste water and aquatic environments. -The reactivity and solubility of critical elements in living systems are highly dependent on redox conditions.
-Measuring the ORP value of a solution
-Investigating differences in ORP value between swimming pool water and water from a ditch
-Measuring redox titrations to determine the equivalence point in an oxidation-reduction reaction
