8" (203mm) Pressure Chart Recorder
Pressure recording with a full 8" (203mm) diameter chart. These 8" (203mm) easy-to-ready pressure charts show 3x as much data as our 4" (101mm) and they are contained in a splashproof enclosure. Create a permanent visual record of your pressure data with the greatest detail.
- 0-100 PSI, 7-Day
- Splashproof case with IP66 rating
- Corrosion resistant case
- Single AA battery operation
Charts are sold separately.

Why should I calibrate?
All instruments lose accuracy over time due to normal usage and the environmental conditions to which they are exposed.
How often should I calibrate?
For most applications, the recommended calibration interval is every twelve months.
What is NIST Calibration?
NIST stands for the National Institute for Standards and Technology. This organization is responsible for maintaining the master for different measurements, such as the standard "foot", standard, "second", or standard "pound". NIST also maintains the standard for temperature, humidity and pressure.
NIST Traceable means that the measuring standard can be traced directly back to the master standard maintained by the NIST organization.
NIST-Traceable does not tell you the measurement accuracy of a metrologty service in any detail. Only metrology services that can document their ISO 17025 standard provided data on their best measurement uncertainty.
Frequently Asked Questions
Make sure the chart is not hung up or restricted.
Make sure the pen does not have too much tension, pinching the chart to the dial plate.
Make sure there is a good battery being used and it's in correctly.
Make sure the center strip of the chart is inserted properly into the black center hub of the recorder, making sure the chart is not ripped or torn.
If the pen does not respond to pressure changes there may be a clog in the capillary. The unit will need to be serviced by Dickson.
What is the tolerance of the unit it is being compared to?
It's ok if the unit is within the sum of the two tolerances
Remember that the unit's tolerance speaks to the Chart Recorder only, there is any additional that applies to the probe
Has an outside calibration house attempted calibration? It may not have been adjusted properly
When was the last time the unit was sent to the Dickson Calibration Lab for a recalibration?
Walk through zero adjustment, found in the manual
For units with Pen Adjustment - rotate screw to adjust the unit to match another unit of greater accuracy after both units have stablized in the same environment.
Chart Recorders - make sure the correct chart is being used.
K-Thermocouple capable units are capable of using any K-type thermocouple probe or extension but keep in mind that long extensions to extend the distance may require a Zero adjustment. (Refer to manual)
As a general rule: If the unit is not responding properly, and you have more than one thermocouple, swap probes to see if it is the probe or the unit that is defective.
Make sure the output signal of the transmitter is calibrated to its full measuring range.
Make sure the range selected on the recorder matches the transmitter exactly and that the proper chart is being used.
Is Pen Arm screw secure?
Is the Chart Recorder sitting on or mounted to a surface prone to vibration?
For Temperature units try removing the unit from the application and placing it in an isolated, low air flow environment like a zip lock freezer bag or desk drawer. If the pen traces straighten out, the traces may have actually been caused by the changes in your application.
