The Fluke Calibration 1529T156 Chub-E4 Thermometer Readout with 4 Thermocouple Inputs features four channels, three major sensor types, lab-quality accuracy, battery power, the ability to read many different sensor types, and much, much more. The 1529-T-156 has four inputs for reading four different sensors simultaneously. With the 1529-T-156, reading thermocouples, PRTs, and thermistors accurately from the same device is no problem. The memory and communications capabilities of the 1529-T-156 make it perfect for lab calibration work, but it is also great for on-site measurements and remote data logging (storing up to 8,000 measurements, including date and time stamps).
