Panel-Mounted
pH Indicators &
Controllers
BL981411-0
and
BL981411-1
are panel-mounted pH indi-
cators and controllers designed for simplicity of use in a wide
range of industrial applications.
Connections and wiring to electrode, power supply and
contacts are made via the terminal blocks on the rear panel.
The meters are equipped with a BNC socket and accept input
from conventional pH electrodes.
Other features include: overtime control system, selection of
dosing direction (Acid/Alk), one dosing contact, 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 981411-0
powered at 12 Vdc
• BL 981411-1
powered at 115 or 230 Vac

ASSEMBLING VIEW
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. The glass bulb at the end of the
electrode is sensitive to electrostatic discharges. Avoid touching this glass bulb 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.
These instruments are warranted for two years against defects in work-
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-
tenance are not covered. If service is required, contact the dealer from
whom you purchased the instrument. If under warranty, report the model
number, date of purchase, serial number and the nature of the failure. If
the repair is not covered by the warranty, you will be notified of the
charges incurred. If the instrument is to be returned to Hanna Instruments,
first obtain a Returned Goods Authorization Number from the Customer
Service department and then send it with shipment costs prepaid. When
shipping any instrument, make sure it is properly packaged for complete
protection.
