Cable and terminals :
The PH202 is equipped with terminals
suitable for the connection of finished
cables in the size: 0.13 to 2.5 mm (26 to
14 AWG)
Cable entry: 2 cable glands 1/2NPT. The cable
glands will form a tight seal on cables with
an outside diameter in the range of 6 to 12
mm (0.24 to 0.47 inches).
Construction : Weather resistant to IP65 and
NEMA 4X standards
Mounting : Pipe, wall or panel mounting, using
optional hardware
Weight : Approx. 1.6 kg
G. Shipping details
: Package size w x h x d
290 x 300 x 290 mm.
11.5 x 11.8 x 11.5 in.
Packed weight approx. 2.5 kg (5lb)
H. Data protection
: EEPROM for configuration and logbook, and
lithium cell for clock.
I. Watchdog timer
: Checks microprocessor
J. Automatic safeguard
: Return to measuring mode when no keystroke
is made for 10 min.
K. Operation protection
: 3-digit programmable password.
L. Sensor impedance checking
: Independent impedance check on measuring
and reference sensor elements, with
temperature compensation. Display of sensor
impedance on message line of display. FAIL
flag in event of “out of limits” impedance, and
the possibility of 21 mA or (3.6 mA or 3.9 mA)
error signal.
M. Signal processing (pH/ORP)
: The PH202 can measure pH or ORP. Using
the FU20 allows simultaneous measurement
and display of pH and ORP. It also allows
display and out put of pH.
N. EMC Conformity standards ,
EN 61326-1 Class A, Table 2
(For use in industrial locations)
EN 61326-2-3
EN 61326-2-5 (pending)
