Product Details
KWS700B Auto - Compensating pH Probe
1.Introduction
The KACISE KWS700B Auto - Compensating pH Probe is a top - notch
tool for precise pH measurement. Thanks to its built - in
temperature sensor, it offers automatic temperature compensation,
which is crucial for accurate readings in different temperature
conditions. It operates within a 0 - 14pH range with an accuracy of
±0.02pH. This probe uses high - performance industrial online
electrodes, allowing for stable long - term work. With RS485 output
and MODBUS protocol, it can be easily incorporated into existing
setups, making it ideal for industries such as hydrology and
wastewater treatment.
2.Feature
- Digital sensor, RS-485 output, standard MODBUS protocol;
- No electrolyte required, strong anti-interference, no need for
frequent calibration;
- Built-in temperature sensor, automatic temperature compensation;
- Adopt high-performance industrial online electrode, can work stably
for a long time;
- Built-in calibration parameters, accurately calibrated at factory,
can be directly installed and used.
