Panel-Mounted
ORP Indicators &
Controllers
BL932700-0 and BL932700-1 are panel-mounted ORP
indicators and controllers designed for simplicity of use in a
wide range of industrial applications.
Connections and wiring to electrode, power supply, contacts
and external recorders are made via the terminal blocks on
the rear panel. The meters are equipped with a BNC socket
and accept input from conventional ORP electrodes.
Other features include: 4-20 mA output, overtime control
system, selection of dosing direction (Rdx/Oxd), contact for
external control and disabling of dosing action, multi-colour
LED for indicating if the meter is in measurement/dosing/
alarm condition, possibility to set (Off-Auto-On switch) dosing
action mode.
Two models are available:
• BL 932700-0 powered at 12 Vdc
• BL 932700-1 powered at 115 or 230 Vac

Recommendations for Users
Before using these products, make sure that they are entirely suitable for the environment
in which they are used. Operation of these instruments in residential areas could cause
unacceptable interferences to radio and TV equipment. Avoid touching the electrode sensor at
all times. During operation, ESD wrist straps should be worn to avoid possible damage to
the electrode by electrostatic discharges. Any variation introduced by the user to the supplied
equipment may degrade the instrument’s EMC performance. To avoid electrical shock, do
not use these instruments when voltages at the measurement surface exceed 24 Vac or 60
Vdc. To avoid damages or burns, do not perform any measurement in microwave ovens.
ASSEMBLING VIEW

manship and materials when used for their intended purpose and
maintained according to instructions. Probes are warranted for six months.
This warranty is limited to repair or replacement free of charge.
Damages due to accident, misuse, tampering or lack of prescribed main-
