MultiSensor water analysis handheld meter for pH, oxygen and conductivity

G 7500

MultiSensor water analysis handheld meter for pH/Redox, conductivity, salinity, dissolved oxygen and temperature, with simultaneous two-channel measurement, IP67 housing, graphic display and USB data logger.

Introduction

Field water analysis often depends on seeing several parameters at the same time. With simultaneous measurement of pH/Redox plus conductivity, salinity or dissolved oxygen, this handheld meter gives you a compact view of water quality directly at the measuring point.
 
The galvanically isolated inputs support reliable parallel measurement with standard sensors, helping keep system costs manageable while preserving flexibility. Applications include surface water monitoring, neutralisation processes, sewage treatment plants, aquaculture, agriculture and vertical or urban farming.
 
Daily work stays practical in the field: the waterproof IP67 housing protects the instrument, the backlit 180 x 128 pixel graphic LCD shows values or measurement curves clearly, and the 8 GB data logger can be read via Micro USB as a USB 2.0 mass storage device. Rechargeable AAA batteries are charged through the same USB connection.

Flexible sensors
Standard BNC and 7-pole connectors support pH, ORP, O2 and conductivity sensors

Features

pH and ORP input

The waterproof BNC input measures -2.00...+16.00 pH or -1500...+1500 mV Redox voltage with Pt1000 temperature input.

Conductivity channel

The second input connects conductivity cells and supports conductivity, salinity and PSU measurement with selectable temperature compensation.

Dissolved oxygen channel

The oxygen channel measures oxygen saturation, concentration and partial pressure with automatic temperature compensation via the connected sensor.

Graphic display views

The monochrome LCD offers large value display, table view and diagram display, with adjustable backlighting and red visual alarm indication.

Calibration functions

The device supports pH 1...5 point calibration with PHL or DIN buffers, conductivity cell constant adjustment and oxygen calibration in water-saturated air.

USB operation

The Micro USB interface provides charging, mass storage access for logger files and COM port communication.

Power and handling

Three interchangeable NiMH AAA batteries power the meter, while the integrated stand and hanging bracket support table, belt or suspended use.
