pH and temperature.
A double-junction water-sample electrode.

The Apera 201DJ-F is a double-junction pH/temperature electrode for general and complex water samples, including wastewater and environmental monitoring. Separate BNC and RCA connections carry the pH and temperature signals.

Verify both meter connections and temperature-sensor support. Calibrate with fresh pH buffers, rinse between samples and use the manufacturer’s electrode-care procedure.

Know what you are ordering.

One 201DJ-F pH/temperature electrode. Meter, buffers and storage solution are separate.

Two connections.
Two measurement signals.

The BNC connection carries the pH signal; the RCA connection carries the temperature signal. The 201DJ-F adds temperature sensing to the double-junction electrode format, unlike the BNC-only 201DJ-C.

Confirm thermistor compatibility with the meter as well as the plugs. Apera describes the electrode for general and complex water samples, including wastewater and environmental monitoring.

A double junction
for aqueous work.

The double-junction reference design is intended for general and complex water-sample workflows. Choose an application-specific electrode if the sample chemistry, temperature or physical form falls outside the published operating window.

Apera specifies 0–14 pH and 0–80°C for the 201DJ-F. The catalog excerpt also identifies the Ø12 × 160 mm body and BNC/RCA format.

Calibrate, measure
and store with care.

Use fresh pH buffers appropriate to your method, rinse between samples and allow the reading to stabilize. Follow the electrode instructions for cleaning and storage.

For a host example, review PH700 with BNC/RCA inputs. Confirm the exact replacement-electrode and temperature specifications for your meter before ordering.

Check the specifications.

Use the complete Product Specifications tab to verify the measurement range, temperature limit, connector and order details against your application.

201DJ-F buyer questions

What is the 201DJ-F used for?

pH and temperature measurement in general and complex aqueous samples, including wastewater and environmental monitoring.

Which connectors does it use?

BNC for pH and RCA for temperature. Confirm the meter supports both connections and the sensor specification.

How does 201DJ-F differ from 201DJ-C?

201DJ-F includes temperature sensing and BNC/RCA connections. 201DJ-C is the BNC pH-electrode version.

What is its pH range?

Apera specifies 0–14 pH.

What sample temperature can it handle?

The catalog specifies 0–80°C (32–176°F).

Is a meter included?

No. This listing is for one replacement electrode.

Is it intended for every non-aqueous solvent?

Apera describes this electrode for water solutions. Select an application-specific electrode when testing solvents or other demanding samples.

What else do I need?

A compatible meter, suitable fresh pH buffers and the manufacturer-recommended care and storage supplies.

Confirm the exact configuration before ordering.
