GENERAL INTRODUCTION   

 

 

Thank  you  for  selecting  the  pH6175  meter.  The  pH6175  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 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 

in 

precise, 

repeatable 

and 

error-free 

measurements. The pH6175 can also be used in non-AUTOLOCK 
mode.     
 
The model pH6175 is available with pH, ORP and ATC (Automatic 
Temperature  Compensation)  probes.  Other  features  include  single 
or  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 

Jenco

 

representative  immediately.  All  packing  materials  should  be  saved 
until satisfactory operation is confirmed. 
 

POWER INPUT                                                                   

       

 

 

The model pH6175 can be powered by an 115V or 230VAC adaptor 
as well as 6 

“AAA” alkaline batteries. Check the label on the AC
