Chapter I. Introduction
This meter is operated by battery(DC 9V) and is controlled by microprocessor for all
measurement needs.
This meter features a custom LCD that simultaneously displays various functions along
with measurement results. istek's instrument is high-performance for accurate
measurement of wastewater and use at laboratory and its operation is simply designed
in the position of user.
This model is capable of storing up to 50 points in memory at once for each items.
pH/ISE/mV/ORP/TEMP Meter
If pH reading is stable, ¡S(Stable)¡ is displayed in the left field, therefore measure
accurately since user can easily know a stable value.
This model is a pH meter which features auto calibration and manual calibration
simultaneously(3 points).
This model displays pH, ISE, mV, ORP(relative millivolt) and ATC(C).
pH indicates power of hydrogen(H+). (unit pH)
pH = -log10[H+]
ISE indicates concentration of any given ion.(unit mg/L) To measure an ion must
use electrodes which according to the type of ion, selectively response to only
any given ion.
mV indicates electromotive force of each ion. (unit mV)
ORP indicates a relative potential. (unit mV)
ATC For automatic temperature compensation, a temperature probe supplied by
istek must be used.
Temperature Compensation is automatically performed while measuring.
DO/O2/Air/TEMP Meter
This model features to obtain a reliable data since its program is treated by setting in
detail about compensation factor(altitude and salinity) for an accurate measurement.
This model displays DO, O2, air and ATC(C).
DO indicates concentration of oxygen presents in the water. (unit mg/L)

O2indicates percentage of oxygen as compared to the amount of oxygen
presents in the air. (unit %)
Air indicates percentage of DO or O2 concentration. (unit %)
ATC For automatic Temperature Compensation, a temperature probe supplied by
istek must be used. Temperature Compensation is automatically performed
while measuring.
Conductivity/TDS/Salinity/TEMP Meter
This model features to obtain a reliable data since its program is treated by setting in
detail about compensation factor(Temperature Compensation Coefficient, Cell
Constant, etc) for an accurate measurement.
This model displays Conductivity(S, mS), TDS(mg/L), Salinity(ppt) and ATC(C).
Conductivity indicates conductivity of solution. (unit S/cm and mS/cm)
TDS indicates by converting the measured conductivity into concentration of the
total dissolved solid present solution from. (unit mg/L)
Salinity indicates by converting the measured conductivity into salinity of solution.
(unit ppt)
ATC For automatic temperature compensation, a temperature probe supplied by
istek must be used.
Temperature is automatically compensated on the base of Tref adjusted in
Setup. Tref indicates compensation temperature. Tref can be set with 25.0℃
or 20.0℃for a basis.
815PDC
This meter features to measure pH, ISE, mV, ORP, DO, O2, Air, Conductivity, TDS,
Salinity and Temp, and automatically select a measuring mode by connection electrode.
If connecting pH electrode, the displays is shown as follows.

Top Panel
Electrode and ATC probe connection
Attach the electrode probe with ATC probe to the DIN jack by sliding the connector
straight on until firmly in place.
RS232C Interface Cable Connection
Insert RS232C interface cable into the RS232C jack. Use interface cable supplied by
istek.
Power Source
Use 1.2V rechargeable battery / DC power adapter
If the message as ¡BAT¡ is displayed, replace battery.
