Description
Introduction | VERITY®1810 Conductivity and pH Monitor
Description
The VERITY® 1810 Conductivity and pH Monitor is a state-of-the-art detection instrument for biological
purifications with a large dynamic range and fast response time for real-time gradient monitoring. It is a
compact, integral component for systems performing oligonucleotide, monoclonal antibody (mAb), and
other biological separations.
The VERITY® 1810 Conductivity and pH Monitor is a USB powered instrument with an integrated conductivity
sensor, an external connection for an optional pH sensor, and analog output connections for conductivity
and pH. Real-time conductivity and pH data can be viewed on an LCD display or monitored either through
the USB connection or analog outputs.

This chapter explains the steps for setting up the instrument, which includes:
●Plumbing Connections on page 18
●Rear Panel Connections on page 19

Plumbing Connections
Installation | VERITY®1810 Conductivity and pH Monitor
Plumbing Connections
Inlet and outlet tubing are ordered separately so as to be appropriate for the application flow rate. Refer to
the Replacement Parts and Accessories appendix for part numbers. Fittings are supplied.
To make the plumbing connections:
1. On each end of the tubing, slide the nut,
then the steel compression ring, and then
the ferrule. The attened end of the ring
should face towards the nut with the narrow
end of the ferrule towards the ring.
2. Insert the nut at each end into its port. (Ports
are not labeled as the direction of the liquid
flow is not specific.) Hold the tubing to the
bottom of the fitting while tightening the
nut to fingertight.
NOTE
If the system includes a pH ow cell, one connection goes to the pH ow cell inlet. Refer to the
pH Flow Cell appendix for instructions and more information.

USB Device port
pH Sensor
The pH sensor cable has a BNC connector.
After assembling the optional pH flow cell, connect the pH sensor
cable to the pH Sensor input, and then twist clockwise 1/4 turn to
lock. For pH flow cell assembly instructions, refer to the pH Flow Cell
appendix.
Output Channels
NOTE
If the VERITY® 1810 Conductivity and pH Monitor is part of a Gilson system, it is not necessary
to make analog output connections. In a Gilson system, make the USB connection between the
VERITY® 1810 Conductivity and pH Monitor and the PC.
The monitor has two output channels: Analog pH and Analog Conductivity. Optionally, direct output from
the monitor to an external device.
To connect an output channel, use one of the supplied cables (part number 11000023). Connect the cable to
the corresponding output port and then twist the nut to secure the connection.
To set the analog output range, refer to Conductivity Analog Endpoint on page 27.
USB Device
The monitor communicates with a standard PC and is powered via
USB.
To make the USB connection between the
VERITY® 1810 Conductivity and pH Monitor and the controlling
device (PC) or power source (USBhub), use the USB cable
(partnumber 32000012) supplied in the accessory kit. Use the
end with the “A-type” (flat) connector to connect to the controlling
device or power source and use the end with the “B-type”(square)
connector to connect to the monitor.
