Chart Recorders

How to buy a suitable chart recorder for tracking different input variables
By Howard Robertson A chart recorder is a data acquisition tool used for plotting an input variable versus time in different visual formats such as strip or continuous charts. Traditional chart recorders use paper for storing and displaying the data, whereas modern chart recorders use an electronic setup.
 

You can use chart recorders for temperature and humidity measurements, chromatography and research works in laboratories.

Some of the important parameters you must consider before purchasing a chart recorder are:

1. Types of input signal for the chart recorder
2. Type of recording: continuous or periodic
3. Range and accuracy of the chart recorder
4. Type of chart: strip, circular, X-Y or hybrid
5. Chart storage methods: paper charts or a memory storage device

Buy a chart recorder from a reputable chart recorder manufacturer

Once you know your requirements, look around for different chart recorders available in the market.
Try: You can find a strip or a circular chart recorder from a broad array of chart recorders from leading manufacturers such as Honeywell and ABB. Opt for paperless chart recorders by CAS Dataloggers to avoid a huge storage of chart recorder paper. You can also select a fluke chart recorder, which is a data acquisition device by Fluke. CoBex Recorders and MicroDAQ.com provide chart recorders for tracking environmental parameters such as temperature and humidity.

Buy specialty or customized chart recorders

For non-standard applications, buy specialty or customized chart recorders that have the capability to record different input variables.
Try: Enercorp Instruments, a digital chart recorder manufacturer, provides customized chart recorders to monitor humidity, temperature and pressure changes. LDS Test & Measurement manufactures specialty chart recorders suitable for vibration test systems. Additionally, Tempco Electric Heater offers customized data acquisition equipment including chart recorders.

Buy a chart recorder from a distributor or a retailer

You can compare chart recorders from different manufacturers at retailers, distributors or associations of manufacturers. These resources are very useful if you are searching for a particular category of chart recorders such as a temperature chart recorder or a humidity chart recorder.
Try: You can get chart recorders by different manufacturers at Test Equipment Connection, a distributor of new and refurbished electronic test and measurement equipment including data acquisition tools. GSAMart is a scientific and technical equipment retailer that offers different instruments including chart recorders.

• As chart recorders are important equipment for testing and analysis systems, consult an expert for chart recorder calibration.
• Use genuine chart recorder parts such as a chart recorder pen and a chart recorder cable.
• For a paperless chart recorder, inquire about details of the memory storage unit.
