ACR DATA LOGGERS

ACR Data Loggers out-perform and out-last competitors products due to the construction techniques and materials chosen to guarantee that data is available at the end of the recording session.

ACR is committed to providing superior products and service as demanded by leaders in industry. Not all data loggers are equal and the axiom “You get what you pay for” still holds true. All of ACR’s products are designed and manufactured under a rigorous quality control scheme that allows us to back up our claims with the best warranties in the business.

What are the differences between ACR Data Loggers and others?

  • ACR has the longest proven Battery Life: 5, 10 and 15* years depending on model / application
  • All our Data Loggers are protected from harsh environments
  • Convenient interfaces between workstation computers and device networks
  • Built under ISO9001:2008 processes focused on customer satisfaction
  • *15 years expected battery life when connected to external power supply

SmartReader

Multi-channel Configurable Data Loggers

ACR SmartReader data loggers are multi-channel, user configurable data loggers that monitor a variety of parameters. Durability is assured with a 3-year logger warranty and 10-year battery life. It is important to note that on competitive products if the replaceable battery comes loose or dies you will not get data – lost time and effort far outweighs any price difference. The SR has more available memory as a result of using a 8-bit converter which is sampled 4 times every 8 seconds for extra stable readings. When the logging interval is set longer than 8 seconds, the readings are further averaged giving a quantitative result (with the exception of the SR7 when Battery Switch is enabled). Software Packages are purchased separately as they can support more than one device.
