Introduction

HI1131B is a glass body, double junction, refillable pH electrode with an indicating sensor made of High Temperature (HT) glass. The double junction reference and HT glass design allow the HI1131B to be used in a wide variety of applications including samples with metals and elevated temperatures. The probe connection to the unit is secured through a galvanically isolated BNC connection.

The HI7662-TW stainless steel temperature probe allows the meter to automatically temperature compensate (ATC) pH measurements. This system responds to a complex range of measurement and monitoring requirements, providing accuracy, reproducibility, and reliability.

User Interface

7-inch capacitive touch screen with multi-touch support

Capacitive touch back, home and system menu keys

User-friendly icons and symbols allow users to easily navigate and interpret the instrument functions

The user can select between five different views:

Basic measurement configuration

Simple GLP with calibration information

Full GLP with electrode status and calibration point details

Live updated, interactive graph

Tabulated data with date, time, and notes

Measurement

Measure pH/mV (pH) or mV/Rel.mV (ORP) with temperature

Application-specific profiles allow quick and direct measurement without the need to update the sensor and system settings

Active log during measurement

Measurement stability indicator (using the Stability Criteria setting)

Reading modes: direct and direct/autohold

Temperature compensation can be Automatic (using temperature probe) or set manually

Audible and/or alarm messages for measurements outside of predefined limits

Galvanic isolation for pH/ORP measurement

Calibration

The HI6221 features 5-point pH calibration capacity with automatic recognition for standard buffers (Hanna and NIST buffers). In addition, a choice of standard or custom buffers for calibration along with non-volatile memory, which saves data and settings
