GENERAL INTRODUCTION

Thank you for selecting the pH6175/6175-3C meter. The

pH6175/6175-3C is a precision tool that measures pH, mV and

temperature. A built-in microprocessor stores, calculates and

compensates for all parameters related to pH determinations

including pH electrode temperature characteristics, electrode slope

deviations and buffer solutions.

This meter has a waterproof IP54 case. The mechanical keys are

highly reliable with tactile and audio feedback. It is powered by six

AAA-size alkaline batteries or with a UL approved AC adapter

(OUTPUT:DC9V). The meter also displays a “BAT” message when

the batteries are in need of replacement. Re-calibration is not

required when power is restored.

The front of the meter has a large LCD with backlight that displays

pH or mV and temperature simultaneously along with user prompts

and mode indicators. The unit prompts the user through calibration

and measurement procedures.

An AUTOLOCK feature for both pH and mV measurements enables

the unit to automatically sense the end point and “LOCK” the display

to indicate the end point value of a measurement. AUTOLOCK and

user prompts help eliminate most errors in determining pH and mV

values,

resulting

precise,

repeatable

and

error-free

measurements. The pH6175 can also be used in non-AUTOLOCK

mode.

The model pH6175/6175-3C is available with pH, ORP and ATC

(Automatic Temperature Compensation) probes. Other features

include single or dual or three point calibration (6175-3C include

dual or three point calibration), electrode offset recognition,

electrode slope recognition, electrode efficiency display, built-in

buffer coefficients, automatic or manual temperature compensation,

long battery life, and 50/60Hz AC noise rejection. This meter is

user-friendly for laboratory application.

INITIAL INSPECTION

Carefully unpack the unit and accessories. Inspect for damages

made in shipment. If any damage is found, notify your Drawell

representative immediately. All packing materials should be saved

until satisfactory operation is confirmed.

POWER INPUT

The model pH6175/6175-3C can be powered by an 115V or
