KWS700B Digital pH Sensor for Water
1.Introduction
KACISE KWS700B Digital pH Sensor for Water is specifically designed
for water - related applications. This digital sensor outputs via
RS485 and follows the standard MODBUS protocol, enabling seamless
networking. It doesn't require electrolyte, reducing maintenance
and interference issues. The built - in temperature sensor adjusts
for temperature changes automatically. With a measuring range of 0
- 14pH and high accuracy of ±0.02pH, it can accurately monitor the
pH of water in water treatment plants, swimming pools, and more.
Its durable POM + Titanium wetted part material ensures long -
lasting use.
