Rated 4 out of 5 by from Value and practical Value 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: AnhT
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.

How often does it require a calibration according to the manufacturer? Does it last for one year or more?

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; HH520 Accuracy is specified for ambient temperatures between 18&deg;C (64&deg;F) and 28&deg;C (82&deg;F). The specifications do not include thermocouple sensor error. &plusmn; (0.1% of reading+0.7&deg;C) OM-HL-EH-TC &plusmn; ( 0.8 C + 0.2 % Reading ) Best regards RS
