Typically Ships Within 21 - 28 Days
Restockable Yes

The "Typically Ships Within" value is an estimate of the number of calendar days within which this product is ready to ship from Campbell Scientific. Orders with more than 10 built-to-order products will likely increase the time needed to prepare the order for shipping.

To estimate how long it will take to receive an order that contains multiple products, combine the longest Ships Within value with the transit time of the shipping method you select.

Some specialized products have long Ships Within values. Because of this, you might consider submitting a separate order for these products so your other products won't be delayed.

Replacement Parts

Desiccant 1/6 unit bag may be purchased to replace saturated desiccant. This desiccant resides inside the canister.
3V Lithium battery 24 mm cell may be purchased to replace a dead or dying battery. This battery powers the clock and RAM when the primary 12 Vdc power supply is not connected.


The 21852 is offered for customers who order a new data logger and require calibration validation from an accredited calibration laboratory. When the 21852 is ordered, Campbell Scientific builds and calibrates the data logger, and then sends it to Simco Electronics in Salt Lake City, UT. After Simco receives the data logger, they perform a calibration validation under the A2LA accreditation. Simco also provides a calibration certificate.
