Chemistry Sensor
(PS-2170)
Specifications
The Chemistry Sensor comes with a Stainless Steel Temperature Probe, pH Electrode, Syringe and
Voltage leads. Any electrode with a BNC connector can be used with the Amplifier. In addition, any
temperature probe with a 3.5 mm stereo plug can be used with the temperature sensor included on the unit.

Calibration
The Amplifier does not require calibration. Refer to the pages on the pH, ORP and ISE electrodes and to the
pages on the Temperature Sensors for specific calibration instructions.
Common Equipment Setup
The PASPORT Chemistry Sensor is designed to operate with any ion-selective electrode, pH and oxidation
reduction potential electrodes. In addition, the PASPORT Chemistry Sensor works with the PASPORT FastResponse, Stainless Steel, and Skin/Surface Temperature probes.
To connect the pH, ORP, or ISE electrode to the amplifier, use the BNC port.
To connect the temperature probes, use the 3.5mm stereo connector.
Tubing setup
Put a drop of glycerin on the barb end of a quick-release coupler. Put the end of the coupler into one end of
a short piece (about 15 cm) of plastic tubing that comes with the PASPORT Chemistry Sensor.
Put a drop of glycerin on the barb end of the other type of plastic connector that comes with the sensor.
Push the barb end of the connector into the other end of the tubing. Fit the end of the connector into the onehole rubber stopper.
Push the rubber stopper firmly into the air chamber (flask, test tube, etc.).
Align the quick-release connector on one end of the plastic tubing with the pressure port of the Pressure
Sensor. Push the connector onto the port, and then turn the connector clockwise until it clicks (about oneeighth turn).
Typical Applications
Titrations (acid-base, potentiometric)
• pH and temperature studies
