## Description

Measurement Computing's USB-502-LCD data logger measures and stores up to 16,379 relative humidity and 16,379 temperature readings over 0 to 100% RH and -35 to +80 °C (-31 to +176 °F) temperature range. The user can easily set up the logging rate and start-time, download the stored data by plugging the module straight into a PC's USB port. The easy-to-install and use USB-500/600 Series software runs in Windows. It allows the user to configure the logger and download and display the data graphically in a powerful strip chart. The software also provides an easy export to Excel. The high-contrast LCD can show a variety of temperature and humidity information. At the touch of a button, the user can cycle between the current temperature and humidity, along with the maximum and minimum stored values for temperature and humidity. The data logger is supplied complete with a long-life lithium battery, which can typically allow logging for up to one year.

## Features

- Stores 16,379 temperature readings and 16,379 relative humidity measurements     Easy to use - no training required     Battery-operated     LCD display shows high/low and last readings     Accuracy: ±0.5 °C (±1.0 °F) ; ±3.0 % RH

    Accurate, easy to use logger... wish it were rechargeable.
  

*by A***D on Reviewed in the United States on March 17, 2018*

This device is relatively easy to use and seems to log accurate measurements. I took it my workplace and compared its measurements with ones taken on calibrated lab instruments. The software it comes with works well, and is easy and intuitive to use.I'd given this five stars except for a few things:When I first got the logger, there were no instructions provided on how/where to install the Li ion battery provided. I incorrectly tried at first by taking a screw out that holds the housing together. I had noticed a small panel that did not easily open but did when I inserted a small wire paper clip into the catch. It would be nice if the battrry panel were marked or better yet, short instruction slip were included in the packaging.Also, the device is not rechargeable (which I knew) but it used more power than I had expected. I initially tested the unit with a fast sampling rate (twice a minute). I left unit in standby for a week before I actually ran my three day test. Then I neglected to remove the data for over a week. This completely drained the battery to the point where I needed a new battery to remove the stored data. I would like this product better if it were rechargeable or could use some battery that is rechargeable. Also, it will not use the USB power when plugged into the computer. It still relies on the battery to be set up and to dump measurements. I now always remove the battery immediately after use.I found that while accurate, the dynamical response of the logger is relatively slow compared to the thermocouple and thermistor probes I used as a reference. The readings lagged during fast temperature changes. This is not really a big deal for monitoring room temperature but I mention this because this is good justification for avoiding rapid sampling rates that tax your battery life. I have yet to see how the batteries last when the sampling rate is slowed.Note that the temperatures are recorded with "integer precision". In other words, no decimal place. This is not surprising since the specified accuracy is a half degree, but I thought the device still may report more precisely, despite its half degree accuracy. Still, this should be acceptable if you just want to track room air temperatures in your house or apartment.

    This thing is amazing.
  

*by M***R on Reviewed in the United States on August 17, 2009*

If you have need for a device to track temperature and Relative Humidity, this is the device. It is small and can easily be placed where needed. I need this to track the outside temperature and humidity for a project I'm working on. The output of the device can be imported directly into an Excel file. I wanted to see what it could do. I live in Phoenix so the top end of the temperature scale is easy to test. I put it first in the refrigerator. It showed me the slight temperature variations as the frig cycled on and off. It showed the dramatic rise in humidity as the door was opened and the cold air in the refrigerator hit the warm air in the kitchen and caused the water vapor to condense. I then put it in the freezer for an hour and after I was done I downloaded the file and was able to see all the amazing data. I look forward to leaving it in my car while the car is parked to see how hot it actually gets in there. The software installed easily and the device is easy to program. The only thing not mentioned in the directions is that the PC doesn't see it as an ejectable drive so... the first time... you just pull it out of the USB drive. There is no Dee Dum sound from the PC so I guess it really doesn't care. The instructions warn you not to remove it while it is doing file transfers. I love mine.

    Software is not that great
  

*by A***R on Reviewed in the United States on April 14, 2012*

I bought a number of these units as well as the Lascar. They are essentially the same.  I have also bought a number of "PYLE PTHDL150" meters.  Overal, the software for the Pyle meters in much better.  I found the readings from meter to meter on the PYLE quite consistent, but a little low (<1 degree).  Unless you really need to have the LCD display I would recomment the PYLE over the Lascar or Measurement computing logger anyday.
