| CR850 | Measurement & Control Datalogger w/Built-In Keyboard & Display | |||
| Temperature Ranges (hide details) | ||||
| -ST | -ST Tested -25 to +50C | |||
|
Every CR850 is tested and guaranteed to perform within published specifications over the standard temperature range. Units are tested and shipped to standard operating range unless extended testing is specified.
|
||||
| -XT | -XT Tested -30 to +80C | |||
|
For extended temperature range testing, analog accuracies are derated approximately two times over published specifications. Extended testing covers the -30° to +80°C range. Batteries are not temperature tested.
|
||||
| Warranty Lengths (hide details) | ||||
| -SW | -SW Standard 3yr Warranty | |||
|
At the time of purchase, the CR850 includes a standard warranty of 36 months. See our full warranty policy in the CR800/CR850 manual for the terms and conditions of this warranty.
|
||||
| -XW | -XW 4yr Warr Extension | |||
|
Our Extended Warranty adds 48 months to the standard 36 month warranty, bringing the total warranty period to 84 months. The extended warranty may be purchased only at the time of original product purchase. It may NOT be "added later." Except for the increased coverage length, the same terms and conditions apply to the extended warranty as apply to the standard warranty.
|
||||
| Calibration Certificate (hide details) | ||||
| -NC | -NC No Calibration Cert | |||
|
The CR850 is shipped without a calibration certificate.
|
||||
| -CC | -CC Calibration Cert | |||
|
When this option is chosen, a two-page calibration certificate is shipped with the datalogger. If you are using the 21852 A2LA/NVLAP Calibration Service, you do not need to order this option because Simco will send you a calibration certificate (see below for a description of the 21852 service).

| Common Accessories | |
| 17565 | CR1000 or CR800 Stack Mounting Kit |
|
The 17565 Stack Bracket allows a small peripheral to be placed under the mounting bracket, thus conserving space. The 17565 Stack Bracket is required to mount a CR850 horizontally in an ENC10/12 enclosure (i.e., the long axis of the CR850 spanning the short axis of the enclosure). Without this bracket, the CR850 can be mounted vertically in the ENC10/12 enclosure, but it will use most of the vertical space.
|
|
| SC32B | Optically Isolated RS-232 Interface |
|
This Optically Isolated Interface is used to attach an AC-powered PC with the CR850. The SC32B includes a cable for connecting with the datalogger's CS I/O port, and includes another cable for connecting with the PC's 9-pin serial port. Customers who want to connect with the PC's USB port instead of the 9-pin serial port should use the SC-USB interface (see below).
|
|
| SC-USB | CSL Optically Isolated USB Interface, 4.9ft Cable |
|
The SC-USB Optically Isolated Interface provides similar functionality as the SC32B, except it connects with the PC's USB port instead of the PC's 9-pin serial port.
|
|
| 17394 | USB to RS-232 Converter DB9 Male, 6ft |
|
The 17394 interface cable provides a USB connector on one end and a 9-pin male RS-232 connector on the other end. The USB connector attaches to the USB port on a PC, and the RS-232 connector attaches to the RS-232 port on the CR850. The cable length is 6 ft (2 m).
|
|
| SC110 | Two RS-232 to Datalogger Control Port Cables, 2ft |
|
The SC110 consists of two cables, each 2 feet (0.6 m) in length. By having two cables, connection of either an RS-232 DCE or DTE device is supported, depending on the cable used.
|
|
| 21852 | A2LA/NVLAP Datalogger Calibration Service w/Calibration Certificate |
|
This service increases delivery time by approximately one week. The 21852 is offered for customers who require calibration validation from an accredited calibration laboratory. When the 21852 is ordered, Campbell Scientific calibrates the datalogger, and then sends the datalogger to Simco Electronics in Salt Lake City, Utah. After Simco receives the datalogger, they perform a calibration validation under the A2LA/NVLAP accreditation. Simco also provides a calibration certificate.

|
| Replacement Parts | |
| 3768 | 2-Pin Screw Terminal Plug Connector .2 inch pitch Straight Wire Entry 12-24 AWG Green Marked G 12V |
|
The 3768 is shipped attached to the CR850. This green, plug-in power connector provides screw terminals for connecting the 12 V and GND wires of the datalogger's power supply. The 3768 may be purchased to replace a lost or damaged power connector.
|
|
| 13519 | 3.6V 1.2Ah Lithium Battery 1/2AA |
|
The 13519 lithium battery powers the clock and SRAM when the primary 12 Vdc power supply is not connected.
|
|
| 10645 | Screw #10-32 x .312 Pan Slot Brass |
|
This ground lug is on the faceplate of the CR850 datalogger just below the green power connector. The 10645 may be purchased to replace a lost or damaged ground lug.
|
|
| 18797 | CR850 Certificate of Calibration for S/N ??? |
|
The datalogger is calibrated to meet ISO/IEC Guide 17025 Requirements and a two-page calibration certificate is shipped.
|
|
| 6554 | Desiccant 1/6 Unit Bag |
|
The 6554 Single 0.16-Unit Silica Desiccant Pack is a very small package used to desiccate the inside of the CR850. Campbell Scientific suggests replacing this desiccant when the lithium battery is replaced.
|
|
| 18634 | CR800 Operators Manual |
|
The 18634 is offered for customers who want a paper CR800/CR850 Operators Manual. This manual comes in a 3-ring binder. The price listed above is for paper manuals ordered without the datalogger. Paper manuals ordered on the same purchase order as the datalogger are available at no extra charge. However, the customer must indicate that they want a paper manual. Otherwise, they will receive a ResourceDVD containing a PDF version of the manual.
|
|
| Services | |
| 18635 | CR800 or CR850 Recalibration w/ Documentation,-25 to +50C |
|
The 18635 requires an RMA (Returned Material Authorization) from Campbell Scientific. When it is ordered, we will recalibrate a CR800 or CR850 to meet original specifications. Recalibration includes standard temperature testing (-25° to +50°C). Before and after calibration sheets are supplied with the datalogger.
|
|
| 18797 | CR850 Certificate of Calibration for S/N ??? |
|
If specified, a two-page calibration certificate is shipped with the CR850. If you are using the 21852 A2LA/NVLAP Calibration Service, you do not need to order this certificate because Simco will send you a calibration certificate (see above for a description of the 21852 service).
|
|
| 18636 | CR800 or CR850 Retested to Extended Temp,-55 to +85C |
|
Retesting is available only for individual units that have previously passed Extended Temperature Testing. Retesting also requires concurrent purchase of recalibration. An RMA (Returned Material Authorization) from Campbell Scientific is required.
|
|
| 18798 | CR850 Tested to Extended Temp (-30 to +80C) |
|
Every CR850 is tested and guaranteed to perform within published specifications over the standard temperature range. Units are tested to standard operating range unless extended testing (-55° to +85°C) is specified. For extended temperature range testing, analog accuracies are derated approximately two times over published specifications. Extended testing covers the -55° to +85°C range. Batteries are not temperature tested.
