RKI Replacement SO2 Sensor ESR-A13D-SO2

$273.21

Ships in 3 - 4 days

Description

The RKI ESR-A13D-SO2 is a replacement sulfur dioxide (SO2) electrochemical sensor for the GX-3R Pro 5-gas confined space monitor and the SC-04 Series SO2 single-gas monitor. The SO2 sensor detects sulfur dioxide in the range of 0 to 100 ppm.

Important: When replacing the sensor on a GX-3R Pro, the instrument firmware must be updated to recognize the new sensor configuration. Use the USB/IrDA downloading cable and follow RKI's IrDA Reprogramming instructions at rkiinstruments.com/download/gx3r-reprograming/.

Compatible Instruments:

Sensor Specifications:

  • Target Gas: Sulfur Dioxide (SO2)
  • Detection Principle: Electrochemical
  • Detection Range: 0 ~ 100 ppm

Frequently Asked Questions

Which monitors is the ESR-A13D-SO2 sensor compatible with?

The ESR-A13D-SO2 replacement sensor is compatible with the RKI GX-3R Pro and the SC-04 Series SO2 single-gas monitor. The sensor detects sulfur dioxide in the range of 0 to 100 ppm using an electrochemical detection principle.

Is a firmware update required when installing the ESR-A13D-SO2?

Yes, when replacing the sensor on a GX-3R Pro. The GX-3R Pro firmware must be updated to recognize the new sensor channel configuration. This is done using the USB/IrDA downloading cable and following RKI's IrDA Reprogramming instructions. The SC-04 Series monitor does not require a firmware update for sensor replacement.

How do I install the ESR-A13D-SO2 replacement sensor?

Remove the rubber boot and open the sensor access cover on the GX-3R Pro or SC-04. Align the replacement sensor module and seat it firmly. If installing on a GX-3R Pro, update the firmware using the IrDA cable before returning the instrument to service. Perform a fresh two-point calibration after installation and confirm alarm setpoints.

How often should the SO2 sensor be replaced?

Electrochemical SO2 sensors typically have a service life of 2 to 3 years under normal operating conditions. Frequent exposure to high SO2 concentrations can shorten sensor life. Calibrate your instrument every 90 days to detect sensor drift before it affects alarm accuracy.
