Temperature and relative humidity data logger

A new data logger that offers a cost-effective solution for recording temperature and relative humidity has been introduced by ACR Systems of Canada

The low priced TRH-1000 Temperature and relative humidity data logger includes software and an interface cable.

The TRH-1000 is a self-contained electronic recording device that measure and records changes in temperature and relative humidity.

When the logger is connected to a Windows-based computer, readings can be viewed as raw data or as graphs.

Its small size, 25mm x 58mm x 81mm, and low weight of only 74 grams (2.6 ounces) make the TRH-1000 ideal for use in confined spaces.

The specification is that the data logger has a temperature range of -40deg C to 70deg C (-40deg F to 158deg F), a temperature accuracy of 0.5 deg C at 25deg C (+/- 0.9deg F at 77deg F).

The Relative Humidity range is 0-100% from -40deg C to 70deg C (-40deg F to 158deg F) with an accuracy of +/- 4% from 20% to 80%.

Memory is 64KB (32,000 data points per channel), with an 8 bit Resolution (1 part in 256): software is TrendReader Express.

The TRH-1000 also offers a wide variety of software selectable options.

Samples can be made at intervals ranging from 8 seconds to 34 minutes.

Sampling method is user selectable, first in first out, stop when full, and delay start, spot and average sampling.

Data can also be easily exported to most spreadsheets.

In addition to being cost effective, the TRH-1000 is built to the exacting standards of all ACR data loggers.

Housed in a Cycoloy (GE Plastics) C120 ABS and polycarbonate case, the TRH-1000 runs off its own 3.6 volt lithium battery.

The battery comes with a five year warranty, and the data logger itself has a one year warranty.

The TRH-1000 represents a breakthrough in Relative Humidity and Temperature data logging, with accuracy, and sampling options that often sell for two or three times as much.

This combination of features and pricing makes it ideal for the price-conscious customer.

The TRH-1000 could be used in areas that include food process verification, pharmaceutical storage, laboratories, transportation, and HVAC.

ACR Systems Inc Information management is the key to a modern successful business.

Albert C Rock realised this when he founded ACR Systems way back in 1982.

Rock could be called a high-tech explorer, always looking for new and better ways to do things.

ACR data loggers grew out of his search for a better way to record temperature and relative humidity in the heating, ventilation, air-conditioning (HVAC) systems he commissioned.

The chart recorders of the day were expensive, unreliable, and prone to messy ink spills and paper jams.

Albert Rock developed a temperature-recording instrument that fitted inside the only small container he could put his hands on at the time - a plastic crayon box.

The rest is history.

ACR data loggers now measure, record, and download to a PC not only temperature, but also relative humidity, AC and DC current, pulse frequency, voltage, air and water pressure, flow, wind speed, RPM, and more.

Most of them are capable of running for 10 years on a single battery.

For added user convenience, each product line uses user-friendly software to download stored information to a PC for on the spot graphing and exporting to spreadsheet and other presentations.

Used in industries ranging from HVAC, transportation, and medical research to manufacturing and aerospace, new applications for ACR data loggers are found every day.

Although ACR Systems is proud of developing a market-driven company that responds to applications in over 100 countries on all continents of the world, it is also dedicated to research and development in order to ensure that the company remains on the leading edge in the field of data logging.

ACR data loggers have so far found many uses flown with airline pilots, raced with Indy car drivers, watched the environmental conditions in Art Galleries and Museums and driven with truckers - and have even been into outer space.

ACR data loggers sit on top, under, and in buildings; they operate in tropical and sub-zero temperatures, in and out of water, and in just about any other place imaginable.
