APERA INSTRUMENTS / 2310-C · 2310T-F / AI1306 / AI1307
Apera’s 2310 series conductivity electrodes have K=10 cell constants for high-range measurement from 20 to 2,000 mS/cm, including concentrated electrolytes and strongly conductive solutions. Both use a platinum-black-coated ring sensor. The 2310-C has BNC connectivity; the 2310T-F adds a 30 kΩ temperature sensor with BNC/RCA plugs. The connected meter must support K=10 and your required measurement range.
Choose the version from the menu above. Apera’s warranty: six months from delivery.
Pick the measurement, then the connector your meter uses (BNC, BNC/RCA with temperature, or 8-pin) on that page. For application-specific pH electrodes, see the LabSen range.

2310-C requires a compatible conductivity BNC input, K=10 support and a suitable measurement range. 2310T-F additionally requires a compatible RCA input for its 30 kΩ thermistor. The electrode’s 2,000 mS/cm upper rating does not extend a lower-range meter.
Built for high-concentration electrolytes and saltwater, up to 2,000 mS/cm.
A proprietary ring sensor coated with platinum black.
Set the host to K=10 and calibrate with appropriate standards. Overall accuracy depends on the host meter, calibration, temperature and sample; do not treat an electrode rating as a complete measurement-system accuracy specification.
Both 2310 models have a 20–2,000 mS/cm electrode range, K=10, a platinum-black-coated ring sensor, POM body, Ø12 × 145 mm dimensions and 3 ft cable. Host range and system accuracy must be checked separately.
The full specification table, version by version, is in the Product Specifications tab.
Rinse with distilled or deionized water before and after use, and store the sensor in its cap filled with fresh distilled or deionized water. Do not rub the sensing ring. Keep the connector clean and dry.
Use a suitable high-range standard, such as 111.8 mS/cm where supported by the host meter. Follow the exact meter’s calibration procedure rather than assuming a lower-range standard is suitable for K=10.
Choose 2310-C or 2310T-F for high-conductivity samples such as concentrated electrolytes and brines. The probe manuals specify 20–2,000 mS/cm, so this is not the low-conductivity pure-water option.
2310-C has a conductivity BNC connector and no temperature sensor. 2310T-F has BNC/RCA connectors and a built-in 30 kΩ thermistor for a compatible temperature channel.
Not necessarily. The meter must support K=10, the selected probe connection and the required high range. The electrode's 2,000 mS/cm rating does not override a lower meter limit.
Both 2310 versions use a platinum-black-coated ring sensor in a POM body. This is a conductivity sensor, not a pH glass membrane.
The 2310-C and 2310T-F manuals specify 12 × 145 mm bodies and 3 ft cables.
Connect to the conductivity input, connect the RCA temperature lead on 2310T-F if the meter supports it, set the cell constant to K=10 and calibrate according to the meter and electrode manuals.
Use a high-range standard supported by your meter and suitable for the working range. A 111.8 mS/cm standard lies within the 2310 probe's stated 20–2,000 mS/cm range; do not assume every lower-range standard is suitable.
Rinse with distilled or deionized water and keep the sensor in its cap with fresh distilled or deionized water, as the 2310 manuals direct. Do not rub the sensing ring, and keep the connector dry.
