HI-729113 pH electrode for Boiler and Cooling Towers with quick connect din connector and titanium body.
The HI-729113 pH electrode for Boiling and Cooling Towers testing is a rugged double junction pH electrode with flat pH sensor and titanium body.
The electrode has a peripheral Teflon junction for maximum surface contact and flat pH tip is easy to clean and prevents solids from collecting on the sensor.
Chemicals used to minimise scale, corrosion and foaming require an optimum pH, measuring and controlling water quality helps minimise these effects.
Ideal for pH measurement of treated boiler, feed water, and steam condensate.
