HBM-100A
HBM-102A

Compact DIN size (96 x 96 mm) panel mount pH/ORP
controllers.
2-point alarm contact output and 4~20mA DC
transmission output are equipped as standard.
The controller is equipped with an automatic, single-action
stability judgment function, which allows for accurate
calibration using standard solutions and helps to eliminate
operator errors. During calibration, the controller determines
the status of the electrode by monitoring its characteristics
and displays diagnostic information in the form of
messages.
Output (measurement) range that can be freely set.
Measurement and display of sample temperature
(0~100ºC).
When the controller enters maintenance (ST-BY) mode, the
previous output value is held and the alarm output is
disabled. This helps to prevent disruptions to the control
system, such as chemical feeds.

The controller automatically switches back to measurement
mode if it is left in maintenance (ST-BY) mode for more
than two hours.
Crack detection function for pH electrode.
Temperature compensation for sample pH value and
pH/ORP value shift functions.

Cleaning signal input: The controller can receive a “cleaning” signal from the chemical and brush cleaners to hold output during the cleaning process.
Temperature compensation for sample pH value: Coefficient setting range…±0.100/ºC Standard conversion temperature…25ºC

Other functions

Manual temperature compensation for glass electrode: Manual temperature compensation is carried out by specifying the sample water temperature.
pH/ORP value shift: Measured value can be shifted within the range of ±1.00 pH/±100 mV. (Temperature shift range: ±5ºC)
Burnout: Output signal can be shifted to the upper or lower limit when there is an abnormality, such as a cracked glass membrane or temperature sensor failure.
Alarm contact output: 2 extra contacts (a-contacts, upper/lower limits can be set freely, no bandwidth limit) (4 contacts in total)

Optional features

Cleaner control output: The internal timer delivers 100V AC power to the chemical cleaner, brush cleaner, and other cleaners.
RS-232 output: A digital communication cable can be used to send the measured pH/ORP and temperature values to a computer.
