Campbell Scientific
Older Campbell Scientific loggers
Certified Campbell Scientific partnerMany stations have loggers that have been measuring for many years. We look after them – programs, troubleshooting and data – and help you replace them when the time comes, so that the data series continues.
Loggers we look after
A selection of older models. Get in touch even if your logger is not listed.
EDLOG
CR10X
A classic measurement and control logger that is still found in many stations.
- 12 single-ended or 6 differential analog inputs.
- Its successor today is the CR1000Xe.
EDLOG
CR23X
A logger with a built-in display and keypad.
- 24 single-ended or 12 differential analog inputs.
- Often replaced by a CR6 or CR1000Xe with an extra analog module.
EDLOG
CR510
A small logger for simpler stations.
- 4 single-ended or 2 differential analog inputs.
- Often replaced by a CR350 or CR310.
EDLOG
21X
An early logger with a built-in keyboard and display.
- 16 single-ended or 8 differential analog inputs.
CRBasic
CR1000
For a long time the standard logger in many stations.
- 16 single-ended or 8 differential analog inputs.
- Replaced by the CR1000Xe.
CRBasic
CR1000X
The predecessor of the CR1000Xe.
- The programs run the same way on the CR1000Xe.
CRBasic
CR800 and CR850
Compact loggers. The CR850 has a built-in display and keypad.
- 6 single-ended or 3 differential analog inputs.
- Replaced by the CR350, or the CR310 when more inputs are needed.
CRBasic
CR3000
A logger with many channels, built-in keyboard and display.
- 28 single-ended or 14 differential analog inputs.
- Often replaced by a CR6 or CR1000Xe with an extra analog module.
CRBasic
CR300 and CR200X
Small loggers for a few sensors.
- Replaced by the CR350 or CR310.
How a replacement works
Survey
We go through the sensors, wiring, program and how data is collected today.
New program
We write the program in CRBasic for the new logger, with the same measurements and tables as before.
Test
The program is tested before the switch, and the values are compared with the old logger’s.
Switch on site
The logger is replaced, the sensors are connected and we check that data comes in as before.
Follow-up
We follow the data for the first days and check that the data series is consistent before and after the switch.
From EDLOG to CRBasic
EDLOG and CRBasic are different programming languages, so an EDLOG program has to be rewritten for a new logger. Campbell Scientific has a tool that helps, but not every instruction can be converted automatically. We rewrite the program and make sure the measurements, calculations and data tables stay the same.
Campbell Scientific no longer offers free support for EDLOG loggers and recommends replacing them with newer models. We keep helping with them until it is time to switch.
Sensors, wiring and enclosure can often stay in place. Sometimes it pays to replace an old sensor at the same time, and then we will tell you.
Frequently asked questions about older loggers
Does an old CR10X still work?
Often, yes. But it is no longer made, so it is wise to plan a replacement before the logger fails.
Do we have to replace the sensors when we replace the logger?
Usually not. Most sensors can be connected to a new logger. We go through the sensors before the switch and tell you if any should be replaced.
Can you retrieve data from an old logger?
Yes. We retrieve data from older loggers and help get it into your system.
How long is the station down during a replacement?
As short a time as possible. We write and test the program in advance, so that only the switch itself is done on site.

Do you have an older logger?
Tell us which model you have and what the station measures, and we will suggest the next step.
