Description

It is a general requirement to record temperatures, voltages, currents, and many physics quantities during research, product development, productions, and quality assurance processes. The number of recorded channels can range from one to several hundred. Thermal/multi-function data loggers are prefect solutions to serve for these measurement and tracking needs.

There are several measurement products in the market to perform such a largescale and extensive time varying recording. Some are expensive, some are limited in accuracy or resolution, and some have low immunity to interference. Chroma thermal/multi-function data loggers are by far the most cost-effective solutions for versatility, accuracy, stability, and interference immunity among this category.

Chroma thermal/multi-function data loggers measure temperatures, voltages, and currents with high accuracy and resolutions. For example, they support 8 types of thermal couples measurement with ITS-90 defined temperature range at 0.3℃ accuracy and 0.01℃ resolution*, while most data loggers in the market are at 1℃ accuracy and 0.1℃ resolution*. Chroma loggers are with 1000VDC channel to channel isolation, which means they can attach thermal couples to objects with high electricity, such as batteries, solar cells, working PCB, etc., and still get correct data. Many competitors simply malfunction, or are even damaged in those cases. Chroma loggers use a parallel architecture for data retrieval, while most of our competitors use a sequential multiplexing method. This means data rate per channel is quick and constant for Chroma loggers, while others become much slower as more channels are used.

Using Chroma thermal/multi-function data loggers, customers get confidence in measured data and high Performance/Cost ratio. Most of all, we can help in certain cases that our competitors fail, and only Chroma succeeds.

*Thermal couple error excluded. Please see specification list for detail.

1000VDC Channel to Channel Isolation

In developing or qualifying some electronic devices, tracking records of temperatures/voltages/currents is required. In many cases there can be high voltage differences between measured points. A switching power supply, for example, is required to measure the primary side voltage/current, secondary side voltage/current, and key component temperatures. Unfortunately, many data loggers including some leading brands are incapable of handling such a high voltage difference between both sides. A difference of a few hundred volts can mess up their measurement entirely, or even kill their loggers.

Chroma thermal/multifunction data loggers are perfect for the measurements in a situation with charge and high voltage difference. The feature of 1000VDC channel to channel isolation makes them immune to voltage difference between any two channels. One just attaches thermal couples or wires on the device or conducting pads and gets accurate data.

Another case can be battery system tests. One needs to know the voltage and temperature of each cell. For other data loggers, often the voltages cannot be measured properly in the cascade configuration. The thermal couple attachment is another issue needing special care. All these problems are easily solved using Chroma thermal/multifunction data loggers for the high channel to channel isolation.

 

0.3℃ Accuracy and 0.01℃ Resolution

Chroma thermal/multi-function data loggers offer higher accuracy and better resolution than our competitors at a comparable, or lower price point. Most data loggers are at 1℃ accuracy and 0.1℃ resolution. Chroma data loggers are 1 order better. Higher accuracy and more detail is always better for measurements.

In order to achieve such high accuracy and resolution, Chroma implements individual CJC for each channel. High bit-count A-to-D converters and an advanced noise suppression circuit makes for outstanding performance in our data loggers. Our customers get better specifications without paying more.

Precise temperatures can be critical in thermal conductivity measurements, chemical processes, and biologic experiments. Testing a heat pipe, for example, often requires resolving <1℃ temperature difference between evaporation and condensing zones. Some liquid crystals can change their properties drastically with a very small temperature variation at critical temperatures.

 

Constant Data Rate Per Channel

Most of data loggers in the market use a multiplexing circuit structure. All channels share a bandwidth which means the more active channels, the slower data rate per channel will be. Chroma data loggers use a parallel data retrieving circuit structure. No matter how many channels are active, the data rate can be as fast as 5 samples per second per channel.

The benefit of constant data rate can be profound for recording large number of channels. For tens of channels, total data bandwidth of Chroma data logger can be several times larger than that of other data loggers. Some other data loggers can become too slow and lose details. They can miss recording critical changes happen in a short time. Chroma data loggers greatly reduce this possibility.
