Replacement Parts

This type T thermocouple was attached to a differential channel when the CR23X was shipped. The programming examples in the Overview Section of the data logger manual use the 3315.
The 905 Single 0.5-Unit Desiccant Bag is used to desiccate the inside of the CR23X. It is often replaced when the lithium battery is replaced.
This green, plug-in power connector is shipped attached to the CR23X dataloggers. The 3768 provides screw terminals for connecting the 12 V and GND wires of the data loggger's power supply.
The 10645 is the screw used in the ground lug.
The 10273 lithium battery maintains power to volatile areas of CR23X memory (e.g., clock) when the main power supply is disconnected or turned off.
The 10695 low profile base can be ordered to replace a damaged base or to retrofit the data logger with a different base. This base is intended for applications where user-supplied batteries are used.
The 10518 rechargeable base can be ordered to replace a damaged base or to retrofit the data logger with a different base. This base includes two 6-V, 7-Ahr sealed rechargeable batteries (see below).
The 8219 is a 6-Vdc, 7-Ahr sealed rechargeable battery used in the 10518 rechargeable base. To provide 12 Vdc, two of these batteries are wired in series. Customers can generally replace the batteries.
The 7843 is the 2-pin, detachable, power supply connector (green) supplied with the rechargeable base. It is easily replaced by the user.
The DCDC18R Boost Regulator accepts an 11 to 16 Vdc input and boosts it to 18 Vdc, which allows automotive supply voltages to recharge the CR23X's sealed rechargeable batteries.
The 8125 is a small, flat-bladed screwdriver that is extremely useful for opening the guillotine terminals on our data loggers and measurement control devices.
The 10871 provides a 9-pin male connector on one end and a 25-pin female connector on the other end. Typically, this serial adapter is used to connect the data logger's 9-pin RS-232 port to a PC's 25-pin RS-232 port.
The 10873 is a serial cable that is useful for connecting the RS-232 port of the data logger to the 9-pin RS-232 port of a computer. The cable is six feet long.


The 15846 is available only for individual CR23X dataloggers that have previously passed extended temperature testing. Retesting also requires concurrent purchase of recalibration (16543).
The 16543 requires an RMA (Returned Material Authorization) from Campbell Scientific. When ordered, the CR23X is recalibrated to meet original specifications. Recalibration includes standard temperature testing (-25° to +50°C). Before and after calibration sheets are supplied with the Micrologger. The calibration price assumes return of a fully functional data logger; charges for all repairs will be added to the invoice.
This service increases delivery time by approximately one week. The 21852 is offered for customers who order a new data logger and, in addition to the Campbell Scientific calibration over the selected temperature range, require calibration verification from a certifying body that is A2LA accredited to the ISO 17025 standards. A paper certificate of the A2LA ISO/IEC 17025 accredited calibration is provided.
The 16157 provides extended temperature testing for the CR23X datalogger; requires a Returned Materials Authorization. Analog accuracies are derated approximately two times over published specifications. Extended temperature testing is typically specified at the time of data logger purchase and performed before the data logger leaves the factory.
The 17155 provides the CR23X Operator's Manual in paper form (bound in a 3-ring binder). This manual was included with all CR23X orders. The CR23X Operator's Manual should only be ordered if you wish to purchase a bound paper copy of the manual as a replacement item.
