USB-500 Series

Hello redrock - Unfortunately, the USB-500 Series, which includes the USB-501-LT are not designed to be submerged in water. They are IP67 compliant which means that they are dust proof and can be immersed in water up to 1 meter for a short length of time. Please contact Sales Engineering at 508-946-5100 to discuss alternative products.

Hello - The USB-501-LT utilizes a CR1620 replaceable lithium button cell battery and the average battery life is 1 month. If a rechargeable battery is desired, please use our USB-501-RCG. For a longer life/replaceable battery, you can always use our USB-501. The USB-501 uses a replaceable lithium ½ AA battery (TEKCELL SB-AA02) and the average battery life is 1 year. The USB-500 series dataloggers are not designed for continuous connection via the USB port. The USB connection is only to be used for configuration and off loading of your data. Continuous connection to a USB port will prematurely drain your battery.

The supplied thermocouple probe (removable) is itself only rated to + 400 deg C. You can connect a different thermocouple (that you procure elsewhere) and with that the logger can read up to +1300 deg C.

There are three configurable options for starting the USB-501-TC-LCD logger.

• 1 – Start Immediately
• 2 – Start when logger button is pushed
• 3 – Start on selected time and date

Dear ARH, The short answer is yes, the USB-501-TC can be used to measure negative temperature readings. To do so you will need to use a different thermocouple that supports your temperature requirements. To explain, thermocouples come with various types of insulation based on how they are going to be utilized. The problem here is that the insulation used on the K type thermocouple (that is included with your order) will not support temperatures below 0 or above 400 degrees C. You will need to locate a manufacturer that offers a thermocouple that supports your requirements. You can review the specifications for the USB-501-TC here: http://www.mccdaq.com/PDFs/specs/usb-500-600-series-data.pdf

Hello Julicorn - The Wifi-500 series data loggers are another solution to accessing data from a different location. With the Wifi-500, users can activate a cloud account (2 devices for free) with remote access. With this set-up, users can view the data from anywhere in the world and receive emails when alarm conditions are met. For more information, please visit http://www.mccdaq.com/wireless-data-acquisition/WiFi-500-Sensor-Series.aspx

Hello Julicorn, thank you for your inquiry. The USB-502 is not designed for real time data access therefore; Web access would NOT be possible. However, our WEB-TC has a built in WEB server so accessing real time data via the internet would be possible using the WEB-TC. You can review the specifications here: http://www.mccdaq.com/ethernet-data-acquisition/WEB-TC.aspx

Yes, the limit for RH and Temperature samples is 16,382 samples. The data logger stops logging data once the 16,382 limit has been attained. You must then off load your data and start up a new logging session. The USB-502-Plus and the USB-502-LCD Series support a” Roll over” feature which allows for continuous data collection by overwriting the data file in a first in, first out set-up.

Hello - The input impedance for the USB-503 is rated at 60 Kohms.

The USB-503 covers a wide input range (0-30V) and has a resolution of 50 mV, so for sure it won’t meet your needs. We also offer the USB-5106, which when paired with the CABLE-ADAP5, results in a 0-5V input range with measurement resolution of 80 uV. The LCD display shows 3 digits to the right of the decimal point, while the log file values have 5 digits to the right of the decimal point.

The LED status description is somewhat lengthy for this response so I recommend that you review the LED status table which is located in the USB-500/600 Help file and can be located here: http://www.mccdaq.com/pdfs/manuals/USB500600Help.zip Under the “Contents” folder double click on the LEDs topic and then scroll down until you get to the USB-503/504 LED status table. As stated above the LEDs are used for notifications other than alarm conditions so I am afraid that a phototransistor would not work in this case.

The USB-503 is a stand-alone voltage data logger that can be connected to any compatible voltage source that needs to be monitored. It is capable of storing up to 32,000 samples of voltage data within a 0-30 volt range. The data is then stored to on-board memory which can then be downloaded to your PC for further analysis.
