P260 Intelligent On-line PH / REDOX(ORP) M nit r
1. INTRODUCTION
The P260 is a micro rocessor controlled H and Redox measurement
instrument. The unit utilizes a multifunction LCD to dis lay readings and
rovide feedback to the user. It is available with different o tion to
rovide fully configurable control, alarm and feedback with u to two
relays and 0/4-20mA current out ut sources. It can be used to detect the
H, ORP value of the solution in chemical, etroleum, rubber, a er,
tobacco, alcohol, sugar, food, mining, smelting, iron and steel, ower
generation, harmaceuticals, water treatment and other industries.
