Temperature Chart Recorders

Yes, Dickson chart recorders are designed to record both temperature and humidity on the same chart. These dual-function recorders have two separate (red and blue) pens, each tracking a different variable, and are often used in environments like cold storage or laboratories where both temperature and humidity control are critical.

Calibration typically involves:

1. Comparing the recorder’s readings with a known, accurate reference thermometer.
2. Adjusting the chart recorder’s sensor until its readings match the reference.

Dickson offers calibration on all of our sensors to ensure ongoing accuracy. Sensors can be swapped at pre-defined intervals so there is no downtime.

Regular calibration is key to maintaining accuracy. Chart recorders should be recalibrated at intervals in alignment with your standard operating procedures (usually yearly or bi-yearly). It’s also important to place the recorder in an area free from interference like direct sunlight, heat sources, or drafts, as these can impact readings.

Chart recorder size: Choose between smaller 4” models that can accomodate physical space requirements and utilize replaceable batteries and the larger 8” models with AC power and higher reading resolution.

Recording range: Ensure the recorder covers the necessary temperature range for your application.

Accuracy: Verify the device’s precision, especially for sensitive environments.

Durability: Look for models built for the specific conditions of your use, such as humidity or dust resistance. Look for features such as polycarbonate casings to ensure durability.

Calibration: Temperature and humidity sensors will drift over time. Consider a chart recorder that offers ongoing OEM calibration.

Chart recorders offer a simple, tangible way to record data without requiring software, batteries, or network connectivity. They’re ideal in situations where reliability and simplicity are more critical than advanced analytics. For regulated environments, chart recorders are often compliant with standards that mandate hard-copy documentation. Additionally, chart recorders work well in settings where digital access is limited or where electronic data loggers may be challenging to deploy.

A temperature chart recorder is a device used to monitor and document temperature changes over time. It has a temperature and/or humidity sensor connected to a mechanical arm with a pen, which moves across a circular chart paper. As the temperature and humidity fluctuates, the pen records these changes on the paper, creating a visual timeline of temperature data. This physical chart serves as a direct record, often used for regulatory or quality control purposes in settings like laboratories, cold storage, or pharmaceuticals. The used charts are often dated and signed to create a representative snapshot for the time period indicated.

A temperature chart recorder is a device used to monitor, measure, and record temperature data over time. It typically consists of a temperature sensor, a recording mechanism, and a chart or digital display for visualizing the temperature data. These devices are commonly used in industries where precise temperature monitoring is critical, such as healthcare, food storage, manufacturing, and environmental monitoring.
