The HH520 is a 4 channel handheld data logger/thermometer that accepts Types J, K, T and E thermocouples. Measurement settings and results are shown on the backlit LCD display. Data can be stored in the data logger and then downloaded to the computer or directly saved on the computer through the USB interface in real time. With the exclusive software, recording/ recalling of data and programming of logging parameters can be done directly through a PC. There is a save dialog window in the software where the data file name and file type to save can be selected. There are three types of file format that can be selected: binary file (*.ghf), text file(*.txt) and Excel® format file (*.csv). The .txt file format can be opened by the HH520 software and any other word processor program like Microsoft® Word or Notepad. The .csv file format can be opened by the HH520 software and also by Microsoft Excel.
The *.ghf file uses much less disk space to save the data than the other two file formats, but it can only be used in the HH520 software.

Value and practicalValue and practical. In stock and prompt delivery. Software may need one more option on grid layout: such as smaller checker board squares on the background to identify data point location. A longer USB cable would be better. On Windows XP, each time the logger is manually powered off and on again and then the hardware driver is automatically installed while USB was plugged in, but need to uninstall and install it again one more time to avoid installation issue. This would need to state in the manual.
Would the rated sampling rate (Sample Rate: 2 samples/sec = 2Hz) applied to all 4 channel at the same time? if less than all 4 is used, can I increase the sampling rate?
Asked by: shredlock
The channels would measure sequentially so using 1 channel will achieve the 2 Hz rate and if the other channels are measuring it would need to have all used channels completed before the next measurement is made on the first channel. There isn't any way to adjust the sampling rate.

What is the resolution of this wireless data logger when connected to SC-GG-T-30-36-PP thermocouple?
My need is 0.1 degree C measurement.
Asked by: Atul
The software displays exact numbers (ex. 73, it would not display decimal points).

What advantage does this new 4-channel unit have over the older OM-HL-EH-TC 8-channel ?? What makes it worth $50 more ??
Asked by: Silver Wizard
Thank you for your inquiry. Biggest advantage of the HH520 is the accuracy spec;
Accuracy is specified for ambient temperatures between 18°C (64°F) and 28°C (82°F). The specifications do not include thermocouple sensor error.

What are the physical dimensions of the unit (length)?
I would need to add the length of the thermocouple plug to find the overall length of the assembly.
I need to verify if it will fit in our enclosure.
Asked by: ScottG
The dimensions of the device are 82.5 L x 25.4 W x 15.2 H mm (3.25 x 1 x 0.6")
A mini-thermocouple connector's dimensions when connected to the transmitter are 20.6 (0.81") by 7.9 (0.31") and the width being 16.8 (0.66)

What is the fastest sampling rate?
Asked by: Simon
Thank you for connecting with Omega. 1 sample per 2 secs is the fastest sampling rate which is depend on the RF reader.
