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/m V/ORP/TEM P M eter
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 = -log
10
[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 /O
2
/Air/TEM P M eter
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, O
2
, air and ATC(
C).
DO
indicates concentration of oxygen presents in the water. (unit mg/L)
