Overview
The AWQ-pH sensor has been designed to perform under hard conditions, from pure mountain water with conductivity as low as 20 μS/cm, lakes and rivers (100 – 2000 μS/cm), seawater with conductivities of 50 mS/cm, to wastewater with conductivity higher than 200 mS/cm.
- pH : 0 to 14
- Redox: -1000 to +1000 mV
- T°C : -10°C to +50°C
- Combination pH/Redox/Temp sensor
- Digital Sensor: Modbus RS 485/SDI-12
- Internal Calibration Data Storage
- pH/ORP Cartridge
Features
Details
This sensor features long-life Plastogel® reference technology, increasing the lifetime of the probe and reducing the need to refill.
The AWQ-pH sensor has been designed for handheld and in-situ applications in some of the most difficult situations for a pH/ORP sensor in term of sensor resistance, quick response, minimal flow dependence and low power consumption.
