Hand-held Data Loggers

The YCT YC-717UD and YC-747UD are hand-held digital thermometers which have thermcouple inputs, via miniature connectors, and can measure seven thermocouple types; E, J, K, N, S, R, T (all channels will measure the set type). The YC-717UD has a single input, where as the YC-747UD has four input channels, all of which are shown on the screen at once, with your chosen channel showing largest in the center of the LCD display.

The instruments can record measurements from all channels, logging up to 10,000 measurements per channel with full time and date recorded, which can be downloaded to a computer and viewed using the supplied Windows software. The data can be saved directly into Microsoft Excel (.xls) file format for further analysis. The software can also be used to log data from the instrument in real time.

The units can be configured with high and low limit alarm and gives out an audiable alarm if any of the channels go outside this limit.

The Data Logger comes with PC based Windows software on CD and an optically isolated USB download lead, and can download its data at up to 50 records per second.

Input	Range	Accuracy	0.1°C Resolution Range
Type J	-100 - 1000°C	±0.1% of reading +0.7°C	-100 - 150°C
Type K	-100 - 1300°C	±0.1% of reading +0.7°C	-100 - 200°C
Type N	-100 - 1300°C	±0.1% of reading +1.5°C	-100 - 150°C
Type R & S	0 - 1700°C	±0.1% of reading +2°C
Type T	-100 - 400°C	±0.1% of reading +0.7°C	-100 - 150°C

Note: The YC-747UD's channels are not isolated from each other, so, to maintain reading accuracy, it should only be used with thermocouples whos junctions are isolated from each other, i.e. not in contact with each other, either directly of via a electrically conductive body.

Rotroinc Part No: HP22

The HygroPalm 22 is a hand-held instrument with interchangeable probe for the measurement of humidity and temperature featuring an integral 2000 point memory and USB interface. The HP22 interfaces with the standard HygroClip2 (HC2-S) probe for environmental measurements, and with the HK25/HK40 probes for measurement in ducts or high temperature applications.

Thanks to the digital interface between the HygroPalm hand-helds and the HygroClip probes, the instrument can be easily applied to a wide variety of other applications such as paper, food, powders and granules. Measurements can also be displayed on the backlit LCD in terms of dew/frost point, with other parameters and functions available, including the transfer of probe log data, when connected to a PC running HW4 software.
