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.

CAUTION ! :
The s ecified erformance of the P260 is entirely de endent on correct
installation. For this reason, the installer should thoroughly read the
instructions before attem ting to make any electrical connections to the
unit.
