A new standalone USB data logger can provide users with more real-time information than any comparable data logger range on the market says Lascar Electronics. The EL-GFX-TC has an on-board dot-matrix display, and it is capable of measuring and storing up to 252,000 temperature readings. The information is resolved to the nearest 0.1 digit, processing data from a single J, K or T-type thermocouple input.
