PH 0 to 14 pH; 0 to 100°C pH controller with temperature compensation
ORP ±2 Vdc ORP controller
The MDS30 Series is a high
performance microprocessor-based
benchtop single or dual input controller
which offers the flexibility to customize
control options. Each unit features
automatic temperature compensation,
two 6 Amp mechanical relays per
controller, and independent
programmable 4 to 20/0 to 20 mA or
0 to 10 V recorder outputs. For ease
of operation all calibration and
parameter setpoints are programmable
through the front keypad. The MDS38
also features two large easy-to-read
13.7 mm (0.54") displays, and can be
interfaced with a large variety of
Industrial or laboratory pH/ORP
electrodes and in-line or submersible
conductivity sensors.
The MDS37 series features single input
and output for pH or ORP. The MDS38
series features a choice of two
independent inputs for controlling pH,
or ORP. Mix and match the controller
inputs to match your specific
parameters. The recorder output
feature for both series allows
the user to interface the controller
directly into a wide variety of process
recorders and Data Acquisition systems
for permanent recording of process
parameters.
